Core Web Vitals Assessment Failed: How Can You Fix It?

To fix the core web vitals assessment: failed issue, you need to identify the core web vitals issues. According to that, this can be achieved by optimizing your LCP, INP, and CLS performances.

Optimization techniques such as Image optimization, lazy loading, browser caching, CSS, and JavaScript optimization can be used to fix the core web vitals assessment: failed issue.

Google clarified that Core Web Vitals is one of the factor that will be used to determine Search Engine Optimization (SEO) rankings. Thus, it is crucial for website owners or developers to ensure that their websites pass this assessment.

If you are a solo-premier or running a small team and do not always have access to a developer, here we will show you how you can solve the issue for your WordPress website using RabbitLoader. Also available for….other platforms

What Are Core Web Vitals?

Let’s understand the core web vitals. Google developed a set of metrics to determine a website’s performance based on the following factors:

• The initial page loading time: how long it takes it to initially load the webpage.
• The user interaction: how fast it responds to the user’s request.
• The web page’s visual stability: how stable the web page is.

Based on the above factor, Google introduced the three main pillars of the core web vital which include: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). 

Largest Contentful Paint (LCP)

The Largest Contentful Paint (LCP) determines how quickly a website loads. This user metric calculates how long it takes for the biggest element on a page, such as a hero image or a large text block, to display on the user’s browser. 

A good LCP performance can improve the website’s loading time as well as the user experience, increasing the conversion rate.

First Input Delay (FID)

First Input Delay (FID) is a metric that determines a web page’s interactivity. It is defined as the span of time between the first user interaction with a web page and the browser’s response to that user interaction.

This user interaction could be tapping on a link, pressing the keyboard, or clicking a button.

Note: Google has introduced a new performance metric, Interaction to Next Paint (INP) to replace the FID.

Cumulative Layout Shift (CLS)

Cumulative Layout Shift (CLS) is a performance metric that determines a web page’s visual stability. It quantifies the amount of unexpected layout shift that occurs during the page’s loading phase.

Unlike the above two performance metrics, Cumulative Layout Shifts (CLS) is not any amount of time, therefore can’t measure CLS in seconds or milliseconds. 

What Is The Meaning Of Core Web Vitals Assessment: Failed?

If one or more of the three performance metrics, LCP, FID, or CLS, on your website, does not meet the threshold values, it indicates that your site does not pass the Core Web Vitals assessment in Google PageSpeed Insights.

• A failed LCP: It takes a lot of time to render the largest element on the web page.
• A failed FID: A poor performance of user interaction.
• A failed CLS: the page’s content shifts during its lifespan.

The Impact Of Core Web Vitals Assessment: Failed

According to the webFX website, 40% of online users will leave a website if it takes more than 3 seconds to render the content. hence if your website fails the core web vitals assessment, it will negatively impact the average on-page time which is an organic ranking factor

According to a survey, almost 70% of users say that an e-commerce store’s website page speed impacts their willingness to buy from it. Therefore, the poor performance of core web vitals can negatively affect your website’s conversion rate.

Not only the conversion rate but also failed core web vitals harm your Google rankings. According to a case study, redBus, the popular bus ticket platform, optimizes its core web vitals. As a result, the conversion rate has improved by 7%. Therefore, we can conclude that for many businesses, this could be a make-or-break factor. 

How To Measure Core Web Vitals?

It’s essential to understand the core web vitals assessment reports and their issues to fix them. When you audit your website’s page speed performance in Google PageSpeed Insights, the first thing you can see is the core web vitals assessment.

Google PageSpeed insights provide the core web vitals assessment based on lab and field data. While the lab data is collected from the laboratory report in the Google Lighthouse in a controlled environment, field data is collected from the Chrome User Experience Report (CrUX).

In order to determine the core web vitals assessment report, Google set some specific values for the core web vitals. For more details, you visit our core web vitals blog.    

Google PageSpeed Insights also provides suggestions for improving the performance of the core web vitals and passing the core web vitals assessment. 

Implementing these suggestions will help you improve your core web vitals performance and boost your conversion rate by providing a seamless experience to your users. Below are the strategies for implementing these suggestions.

FAQ: what are the helpful tools to identify the core web vitals issues and optimize them?

There are several tools available online to identify your website’s issues that are failing you the core web vitals assessment. While tools like GTmatrix allow you to test individual pages for free, you might have to invest a little bit if you need a detailed assessment for the entire website on tools like GTmatrix, and DebugBear.

To fix the issues, you can either hire a web developer or use a tool like RabbitLoader which helps you optimize your entire website for the best performance.   

How To Pass The Core Web Vitals Assessment?

Here, we will discuss the most common Google PageSpeed Insights warnings and how you can easily mitigate them using RabbitLoader and passing the core web vitals assessment. 

Efficiently Encode Images

The Efficiently Encode Images warning in PSI indicates that you need to optimize your images to reduce their size without harming their quality. This could be done using lossless compression, a technique that reduces an image’s size without sacrificing its original quality.

Any uncompressed image on your page would result in a larger page size for your website since the unoptimized image itself has a higher file size. Learn more with our previous blog.

Let’s see how RabbitLoader mitigates this issue. 

• Losslessly Compressing The Images

Compressing large images can reduce their size. There are two types of image compression: lossless compression, which compresses images without sacrificing quality, and lossy compression, which reduces the image size along with its quality.

RabbitLoader’s in-built lossless compression capability reduces image size without sacrificing quality.

• Optimizing Images By Converting Them Into Next-Gen Formats

Another effective method for resolving this Efficiently Encode Images warning is image optimization. You can resolve this issue by converting your large-sized JPEG and PNG images into next-gen image formats such as AVIF and WebP.

An in-built bulk image optimizer in RabbitLoader can convert your all PNG and JPEG images to WebP and AVIF formats. Converting them to these next-gent formats can save approximately 39% of your image loading times. 

Reduce Initial Server Response Time

The time it takes for a server to respond to a browser request is known as the server response time. If your website takes a long time to respond to the browser request, you will come across this page speed warning “Reduce Initial Server Response Time”.

Let’s see how RabbitLoader can help you to resolve the “reduce initial server response time” warning. 

• Browser Caching 

Using a browser caching technique can significantly reduce the initial server response time by temporarily storing your static resources in the browser cache during the first visit. When the visitor revisits the site, the cached content is rendered from the browser cache, reducing server response time. 

When optimizing your website by using RabbitLoader, it takes care of your browser caching and also adds the cache invalidation to keep your cached control stale-free.  

• Content Delivery Network

Due to the high physical distance between the visitor and the server, network latency can occur, increasing the initial server response time. It would negatively affect your user experience.

By using a premium Content Delivery Network (CDN) with 300+ edge/ proxy servers, RabbitLoader can reduce the initial server response time by minimizing the network latency. 

• Load The Above-The-Fold Images First 

During web page rendering, the browser generally first loads all of the page’s assets, which can increase the initial server loading time. By implementing lazy loading, you can only load the assets essential to render the above-the-fold content first.

RabbitLoader defers your below-the-fold graphics by enabling the lazy load optimization technique. This reduces the server response time and enhances the performance of the core web vitals, particularly LCP, CLS, and INP.

• Generating Critical CSS Files For The Above-The-Fold Content

The CSS rules required to render the above-the-fold content, are known as critical CSS. Therefore, these styles are essential for rendering the above-the-fold content. By generating critical CSS, you can reduce the initial server response time. For more details visit our previous blog.

RabbitLoader identifies the critical resources of your webpage and generates a separate file. This can help you to improve the core web vitals performance especially LCP and INP performance.  

Avoid Enormous Network Payloads

If your website’s page size exceeds the recommended size (less than 1600 KiB), Google PageSpeed Insights triggers the error “Avoid Enormous Network Payloads” for pages that do not adhere to this recommendation. Therefore, to mitigate this warning, you need to optimize the core web vitals by following the below techniques along with the above techniques:

• Minify Stylesheets, Scripts, And HTML Files

Minifying stylesheets, scripts, and HTML files can reduce the total page size by reducing the unnecessary characters from these files. These unnecessary characters can be comments, line breaks, and white press which developers often use to increase the readability.

RabbitLoader minifies these resources to mitigate this Avoid Enormous Network Payloads warning and improve your core web vitals performance.

• Compress All Resources Files

Compression is a technique for reducing the size of CSS and JavaScript files by reducing the redundancy of the code. In simple words, by compressing, you can replace the repeated strings with a single pointer, decreasing the page size.

Resource compression can be of two types: GZIP and brotli. While GZIP is the traditional compression technique, brotli uses the modern compression method. RabbitLoader uses brotli compression and helps you pass the core web vitals assessment by optimizing them.     

• Reduce Unused CSS

Reduced unused CSS is the most common Google PageSpeed Insights warning if you don’t use one or more than one CSS style on your website but define it in the stylesheets. This also increases the page size.

When you are using RabbitLoader for website optimization, in the optimized version, you get a new CSS file where only the required CSS rules will be present. Therefore, your page size will be significantly reduced, which will positively affect your core web vitals performance.

Image Elements Do Not Have Explicit Width And Height

Adding an image without setting the proper width and height can trigger the “image elements do not have explicit width And Height” warning. This is one of the most common reasons for your poor CLS score.

RabbitLoader automatically resizes your images to fit every screen size, preventing shifting and enhancing both the user experience and CLS performance. Therefore, you can easily pass the core web vitals assessment. 

Avoids An Excessive Dom Size

The browser creates a DOM tree during web page loading. A large DOM size often increases memory usage, and so does the webpage loading time, affecting your core web vitals assessment. To solve this warning, you can follow the techniques:

• Avoid Using Third Party Script

When you use a third-party script, like Google ads, the DOM size can be increased, slowing your website’s page speed. So, in order to pass core web vitals, you need to avoid using third party scripts.  

• Don’t Use Too Many Optimization Plugins

Plugins can optimize your website’s page speed performance, but sometimes, using too many plugins can decrease your website’s performance. They also have stylesheets and scripts. During a page, these files need to be executed, slowing your website by increasing the DOM size.

RabbitLoader is an all-in-one optimization tool with 10+ optimization features that prevent the use of too many optimization plugins, mitigating this “avoid an excessive DOM size”. Therefore you don’t need to invest your money in using different optimization plugins.    

RabbitLoader is able to reduce the DOM size by compressing your HTML file. Also when you are using RabbitLoader, you don’t need to use too many plugins. As you can see, RabbitLoader can optimize almost all resources, thus, you don’t need to use too many plugins.

Minimizes Main-Thread Work 

Google PageSpeed Insights triggered the “Minimize main-thread work” warning if the main thread is blocked by the other tasks. This is one reason your core web vitals assessment might fail,

Minimizing the main thread work can speed up your website and improve the performance of Interaction to Next Paint (INP). The best practice is to optimize your JavaScript files to minimize the main thread work.

• JavaScript Optimization 

JavaScript file is used to make an interactive web page and increase the average on-page time. However, JavaScript blocks the main thread and increases the INP time. 

Some JavaScript functions are needed during the initial loading time like any warning or alerting pop-up. Apart from these functions, RabbitLoader defers the rest of the non-priority JavaScript functions, improving the initial loading time.

In addition, RabbitLoader supports multithreading, so we can use other threads simultaneously if the main thread becomes busy.

Eliminate Render-Blocking Resources

An unoptimized image, unused CSS, and JavaScript files block the main thread and act as render-blocking resources. Because of them, you can see the warnings “eliminate render-blocking resources”.

Therefore by optimizing the image, CSS, and JavaScript file, you can easily eliminate the render-blocking resources and pass the core web vitals assessment. We have already discussed the optimization techniques.

A quick recap of the core features of RabbitLoader:

Conclusion 

Is your Core Web Vitals assessment: Failed in Google PageSpeed insights? As discussed, it directly affects your user experience, conversion rate, and Google rankings. By optimizing your core web vitals you can easily pass the core web vitals assessment.

Here we have mentioned a non-coding solution, RabbitLoader which can help you pass the core web vitals assessment and increase the overall score in Google PageSpeed Insights.

Optimizing Your Largest Contentful Paint Score: A Comprehensive Guide

In today’s digital age, speed is everything. With millions of websites vying for attention, it’s essential to ensure your website is not only attractive but also fast. Slow-loading websites often result in visitors bouncing off the site, leading to a loss of potential customers. This is where the concept of web performance optimization comes in. Web performance optimization (WPO) is the process of making websites faster and more efficient, making it easier for users to access the content they need. In this blog post, we will discuss one of the most important aspects of WPO – the Largest Contentful Paint (LCP).

What is the Largest Contentful Paint (LCP):

Largest Contentful Paint (LCP) is one of the Core Web Vitals that measure the loading time of a website’s largest content element. In simpler terms, the Largest Contentful Paint measures the time taken by the website to load the largest image or text block visible on the screen. This is important because users tend to focus on the most prominent content when they first land on a website. Therefore, if the largest element of your web page takes a long time to load, it can negatively impact the user experience.

FAQs:

What are Core Web Vitals?

Core Web Vitals is a set of metrics that measure key aspects of a website’s user experience. Google introduced them as part of its effort to improve the quality of the web and help website owners create websites that are fast, user-friendly, and engaging.

The three Core Web Vitals are:

1. Largest Contentful Paint (LCP) – measures the loading speed of the largest image or block of text visible in the viewport.
2. First Input Delay (FID) – measures the time it takes for a web page to become interactive, meaning the time between when a user clicks on a button or link and when the page responds to that action.
3. Total Blocking Time (TBT) – measures the amount of time a web page is unresponsive to user input during loading. This can happen when the page is loading a large number of resources, or if the page’s main thread is busy executing JavaScript code or rendering the page’s layout.

What is FCP?

First Contentful Paint (FCP) is a performance metric used to measure the loading performance of a website. It refers to the time it takes for the browser to render and display the first meaningful content, such as text or images, on the page after a user navigates to it.

Why is the Largest Contentful Paint important?

As mentioned earlier, the Largest Contentful Paint metric is crucial because it determines the loading time of the most prominent content on a web page. The faster the Largest Contentful Paint, the better the user experience, and the higher the chances of retaining visitors on the site. On the other hand, a slow Largest Contentful Paint can lead to visitors abandoning the site, resulting in lost business opportunities.

 A good Largest Contentful Paint score is a key component of a positive page experience, which is a significant ranking factor for Google’s search engine algorithm.

FCP

LCP

There are several reasons why Largest Contentful Paint is important:

1. User Experience:

 The Largest Contentful Paint metric is closely related to user experience. If a web page takes too long to load, users may become frustrated and leave the page. By optimizing for LCP, web developers can create a better user experience, which can lead to higher engagement, more time spent on the site, and increased conversions.

2. Search Engine Rankings:

 Google has indicated that Largest Contentful Paint is a key metric for its Page Experience algorithm, which is used to rank websites in search results. Websites that have a fast LCP are more likely to rank higher in search results, which can lead to increased traffic and visibility.

3. Mobile Performance:

 LCP is particularly important for mobile devices, as they often have slower internet connections and less processing power than desktop computers. By optimizing for LCP, web developers can ensure that their site loads quickly on mobile devices, which can lead to higher engagement and conversions.

How to improve LCP score?

Improving the LCP score can be challenging, but it is necessary to provide a better user experience. Here are some tips to improve the LCP score:

1. Optimize Images: 

Images are often the largest content element on a web page, and optimizing them can significantly improve the LCP score. Use the appropriate image size and format to reduce the file size and load time.

2. Minimize JavaScript and CSS: 

Large JavaScript and CSS files can cause a delay in the loading time of the largest content element. Minimizing them can significantly improve the LCP score.

3. Use a Content Delivery Network (CDN):

 A CDN can reduce the distance between the server and the user, reducing the loading time of the largest content element.

4. Implement Lazy Loading:

 Lazy loading is a technique that only loads images or other content as the user scrolls down the page. This can improve the LCP score as it prioritizes the loading of the most important content.

5. Use Critical CSS: 

Critical CSS is a technique that only loads the CSS required for above-the-fold content. This can help the largest content element load faster, leading to a better LCP score.

6. Reduce Server Response Time: 

Slow server response time can cause a delay in the loading time of the largest content element. Optimize the server response time to improve the LCP score.

FAQs:

What is a Good LCP Score?

A good LCP score is typically below 2.5 seconds.

How is the Largest Contentful Paint score measured?

There are several tools available to measure the Largest Contentful Paint score, including PageSpeed Insights, Chrome User Experience Report, and Google Lighthouse. These tools provide insights into the loading time of the page.

Measuring the Largest Contentful Paint (LCP) score is essential to assess how fast a web page loads its largest contentful element.

Largest Contentful Paint is a critical Core Web Vitals metric that measures the loading speed of a web page, specifically how fast the largest image, video or text block is rendered on the screen.

Improving the Largest Contentful Paint (LCP) score of a website is essential to ensure a fast and seamless user experience, reduce bounce rates, and improve search engine optimization (SEO) ranking. In this section, we will discuss various techniques and tools to improve the LCP score of a website.

1. Optimize Images and Videos:

Images and videos are essential elements of modern websites. They attract users and keep them engaged. However, they can also be a significant factor in slowing down the Largest Contentful Paint score of a website. Hence, it is crucial to optimize images and videos for fast loading. Here are some ways to do that:

• Compress Images and Videos: Images and videos that are large in size can significantly slow down the Largest Contentful Paint score. Therefore, it is essential to compress images and videos to reduce their file size. This can be done using various online tools or image optimization software. Compressing images and videos can also reduce the bandwidth required to load them.

• Use Appropriate Image and Video Format: Using the appropriate image and video format can also help in improving the Largest Contentful Paint score. For example, JPEG and PNG formats are commonly used for images, and MP4 and WebM formats are used for videos. Using the appropriate format can reduce the file size and, in turn, improve the Largest Contentful Paint score.

• Lazy-Load Images and Videos: Lazy-loading images and videos means that they will only load when the user scrolls down to them. This can improve the Largest Contentful Paint score as only the visible images and videos will load initially.

2. Minimize Server Response Time:

Server response time is the time taken by the server to respond to a user’s request. Slow server response time can significantly slow down the LCP score. Here are some ways to minimize server response time:

• Use Content Delivery Network (CDN): A CDN is a network of servers that can help reduce the distance between the user and the server. This can improve server response time and, in turn, improve the LCP score.

• Enable Caching: Caching can help reduce the server response time by storing frequently accessed data on the user’s browser. This means that the server doesn’t have to generate the same data repeatedly, thus improving the LCP score.

• Optimize Server-side Code: Optimizing the server-side code can also help reduce server response time. This can be done by minimizing database queries, reducing the number of HTTP requests, and optimizing the code.

3. Prioritize Critical Resources:

Loading critical resources, such as the largest contentful element, first can significantly improve the LCP score. Here are some ways to prioritize critical resources:

• Load the Largest Contentful Element First: The largest contentful element should load first, followed by the other resources. This will ensure that the user sees the most critical content first.

• Defer Non-critical Resources: Third-party scripts, tracking codes, and other non-critical resources should be deferred to improve the LCP score.

4. Reduce Client-side Rendering Time:

Client-side rendering is the amount of time it takes for the browser to render the HTML, CSS, and JavaScript. Slow client-side rendering can significantly slow down the LCP score. Here are some ways to reduce client-side rendering time:

• Minimize JavaScript and CSS: Minimizing the amount of JavaScript and CSS used can significantly reduce client-side rendering time. This can be done by using minified versions of JavaScript and CSS and removing unnecessary code.

• Optimize Code: Optimizing the code can also help reduce client-side rendering time. This can be done by avoiding unnecessary loops, reducing the number of HTTP requests, and optimizing the code.

• Use Browser Caching: Using browser caching can help reduce client-side rendering time by storing frequently accessed data on the user’s browser.

All these optimizations can be done manually in a time and money-consuming process or it can be done by optimization tools like RabbitLoader that will do all these optimizations for you and help improve your websites speed which in turn will have you improve the ranking of your webpage on search engines.

Total Blocking Time: 5 Best Ways of Improving User Experience

Total Blocking Time (TBT) is a key metric that measures the time between the user’s input and the moment when the page becomes responsive. It is an essential metric that affects the user experience, especially page loading times.

The speed and performance of a website can have a significant impact on its success. A fast-loading, responsive site can keep visitors engaged and improve user experience, while a slow or unresponsive site can cause frustration and drive visitors away.

As a result, website owners and developers are constantly looking for ways to optimize their sites for performance.

In this blog post, we will discuss Total Blocking Time and how it affects web performance. We will also provide insights on how to improve Total Blocking Time and boost the overall user experience. By the end of this post, you will have a comprehensive understanding of Total Blocking Time and the role it plays in website performance, and be better equipped to optimize your own site for success.

Understanding Total Blocking Time:

Total Blocking Time is a web performance metric that measures the time between the user’s input and the point when the web page becomes interactive. It is a critical metric because it affects the user’s experience, especially when it comes to the website’s responsiveness.

The Core Web Vitals initiative introduced Total Blocking Time as one of the essential metrics for measuring page loading speed. Total Blocking Time measures the duration between the first interaction and the time when the web page’s main thread becomes idle.

Main thread idle time is a time when the browser has finished loading the page’s critical resources, and the browser is no longer busy with any other tasks.

The Total Blocking Time score is measured in milliseconds, and it should not exceed 300 ms for a good user experience. When Total Blocking Time exceeds 300ms, the user will perceive the page as unresponsive, which will lead to frustration and abandonment.

FAQs:

What is the difference between Total Blocking Time and other web vitals?

Total Blocking Time is one of three Core Web Vitals, which also include the Largest Contentful Paint (LCP) and First Input Delay (FID). LCP measures how quickly a page’s main content is loaded, while FID measures how quickly a page responds to user input.

Importance of TBT in Core Web Vitals:

Total Blocking Time (TBT) is one of the three Core Web Vitals that Google has identified as critical for providing a good user experience on the web. The other two Core Web Vitals are Largest Contentful Paint (LCP) and First Input Delay (FID).

Total Blocking Time measures the amount of time a web page is unresponsive to user input during loading. This can happen when the page is loading a large number of resources, or if the page’s main thread is busy executing JavaScript code or rendering the page’s layout.

Total Blocking Time is an important performance metric because it directly impacts user experience. If a web page takes too long to become responsive to user input, users may become frustrated and abandon the page. This can lead to lower engagement and revenue for your website.

In contrast, websites that provide a good user experience are more likely to see higher engagement and conversion rates.

By monitoring and optimizing Total Blocking Time, website owners can ensure that their site is providing the best possible user experience, which can lead to improved rankings and increased revenue.

Google has set a threshold of 300ms for Total Blocking Time, meaning that pages with a Total Blocking Time score of more than 300 ms are considered to have a poor user experience. As such, website owners should aim to keep their Total Blocking Time score as low as possible, ideally below 300ms, in order to provide a good user experience.

By optimizing for Total Blocking Time, website owners can not only improve their user experience but also boost their search engine rankings. This is because Google’s page experience algorithm takes Core Web Vitals, including Total Blocking Time, into account when ranking websites in search results.

In summary, Total Blocking Time is a critical component of Core Web Vitals and an important performance metric that website owners should monitor and optimize. By keeping their Total Blocking Time score low, website owners can provide a good user experience, improve their search engine rankings, and increase engagement and revenue for their websites.

FAQs:

What are core web vitals?

Core Web Vitals is a set of metrics that measure key aspects of a website’s user experience. They were introduced by Google as part of its effort to improve the quality of the web and help website owners create websites that are fast, user-friendly, and engaging.

The three Core Web Vitals are:

1. Largest Contentful Paint (LCP) – measures the loading speed of the largest image or block of text visible in the viewport.
2. First Input Delay (FID) – measures the time it takes for a web page to become interactive, meaning the time between when a user clicks on a button or link and when the page responds to that action.
3. Total Blocking Time (TBT) – measures the amount of time a web page is unresponsive to user input during loading. This can happen when the page is loading a large number of resources, or if the page’s main thread is busy executing JavaScript code or rendering the page’s layout.

TBT Score and User Experience:

Total Blocking Time is a crucial metric for user experience. A high Total Blocking Time score indicates that the website is taking too long to respond to the user’s input, making the website feel slow and unresponsive. This leads to a poor user experience, which can have a significant impact on the website’s success.

Google Pagespeed Insights and Lighthouse scores use Total Blocking Time as a key metric for evaluating a website’s performance. A high Total Blocking Time score can affect the website’s performance score and negatively impact the user’s experience.

The Total Blocking Time score is directly related to the website’s loading time, which is why website owners should always aim to reduce it. A low Total Blocking Time score indicates that the website is fast and responsive, leading to an excellent user experience and higher engagement rates.

Improving Total Blocking Time:

Improving TBT involves optimizing several key areas of website performance. Below are some strategies to reduce TBT and improve the overall user experience.

1. Optimize Server Response Time:

Server Response Time (SRT) is the time it takes for the server to respond to a user’s request. A slow SRT can significantly increase TBT, leading to a poor user experience. Website owners can optimize SRT by using a Content Delivery Network (CDN) and optimizing server-side scripts.

2. Optimize JavaScript Execution:

JavaScript is a crucial component of modern websites. However, large JavaScript files can significantly increase TBT. Website owners can optimize JavaScript execution by minimizing the size of the JavaScript files, removing unused JavaScript code, and deferring non-critical JavaScript files.

3. Optimize Web Page Performance:

A poorly optimized web page can significantly increase TBT. Website owners can optimize their web pages by reducing the number of HTTP requests, compressing images, using lazy loading techniques, and optimizing CSS and HTML code.

A Guide to Resource Loading and its Importance in Web Development

Resource Loading is a crucial aspect of web development that plays a significant role in the user experience, search engine optimizations, and cross-device compatibility of a website. It refers to the process of fetching and downloading the various elements and resources of a website, such as images, videos, stylesheets, and scripts, from a server to the user’s browser. 

In this blog post, we will delve into the world of Resource Loading and its significance in web development. From explaining what Resource Loading is and how it works to exploring the importance of Resource Loading for user experience, SEO, and cross-device compatibility, this post will provide you with an overview of everything you need to know about Resource Loading. Additionally, we will cover best practices for Resource Loading, common challenges, and solutions to ensure that your website is optimized and runs smoothly.

What is Resource Loading? 

Resource Loading refers to the process of fetching and downloading resources from a server to the user’s browser. The resources loaded on a website can include images, videos, stylesheets, and scripts, among others. These resources are then used to render the website for the user. 

There are two types of resources that can be loaded on a website: blocking and Non-blocking resources. Blocking resources are resources that must be loaded before the page can be displayed, such as stylesheets. Non-blocking resources are resources that can be loaded asynchronously, in parallel with the main page, such as images and scripts. 

The loading process begins when the user requests a page by entering its URL in the browser. The browser then sends a request to the server, which sends back the HTML file, along with any other resources that the HTML file calls for. The browser then parses the HTML file and requests any additional resources that the HTML file calls for, such as images, stylesheets, and scripts. 

Once the resources are fetched and loaded, the browser can display the complete webpage to the user. The loading process can take anywhere from a few milliseconds to several seconds, depending on the style and complexity of the website, as well as the user’s internet connection speed. 

Importance of Resource Loading: 

Resource Loading is an important aspect of web development for several reasons, including: 

1. User Experience and Page Speed: 

The speed at which a website load is crucial for user experience. If a website takes too long to load, users may become frustrated and leave the site, leading to a high bounce rate. This can negatively impact the website’s search engine rankings and overall user engagement.

2. Search Engine Optimization: 

Search engine optimization (SEO) is the process of optimizing a website to rank higher in search engine results pages (SERPs). One of the factors that search engines use to rank websites is page speed, and this includes the speed at which resources load, a fast-loading website is more likely to rank higher in SERPs than a slow-loading website.

3. Responsive Web Designs and Cross-Device Compatibility: 

In today’s world, it is important for websites to be accessible on a variety of devices, including desktops, laptops, tablets, and smartphones. Resource Loading plays a crucial role in responsive web design and cross-device compatibility, as the resources must be loaded quickly and efficiently, regardless of the device or connection speed being used.

4. Performance and Scalability: 

Optimizing Resource Loading can also improve the overall performance and scalability of a website. A slow-loading website can result in high bounce rates, low engagement, and poor user experience, which can have a negative impact on the performance and scalability of the site. 

On the other hand, a fast and efficiently loaded site can ensure that the site is able to handle increasing traffic and provide a positive experience for users.

Resource Loading is an essential aspect of web development that plays a key role in the user experience, SEO, cross-device compatibility, and performance and scalability of a website. By optimizing Resource Loading, you can ensure that your website provides a fast and seamless experience for users and that it is able to perform well and scale as your traffic grows.

Measuring Resource Loading: 

Resource Loading can be measured in several ways: 

1. Page Load Time: 

Page load time is one of the most common metrics used to measure Resource Loading. This metric measures the time it takes for a page to fully load, including all of its resources, such as images, stylesheets, scripts, and fonts. 

Page load time is an important metric as it provides a direct measure of the user experience, as users expect pages to load quickly and efficiently.

2. Time to First Byte(TTFB): 

Time to first byte (TTFB) is another metric that measures Resource Loading. TTFB measures the time it takes for the first byte of data to be received from the server after a request has been made. 

This metric provides insight into the performance of the server and the efficiency of the resource-loading process.

3. Page Weight: 

Page weight is a metric that measures the total size of a page, including all of its resources. Page weight is an important metric as it directly affects the page load time, with larger pages taking longer to load.

 By optimizing the page weight, you can reduce the page load time and improve the user experience.

4. Resource Load Time:

Resource load time is a metric that measures the time it takes for individual resources to load. This metric provides insight into the performance of specific resources that help identify any resource that may be slowing down the page.

5. Performance Tools:

There are various performance tools available, such as google page speed insights, google lighthouse and GTmetrix, that can be used to measure Resource Loading. These tools provide a comprehensive analysis of Resource Loading, including metrics such as page load time, TTFB, page weight, and resource load time, as well as recommendations for optimizing Resource Loading.

Resource Loading can be measured in several ways, including page load time, TTFB, page weight, resource load time, and using performance tools. By measuring Resource Loading, you can gain insight into the performance of your website and identity any areas that need optimization to improve the user experience.

FAQs:

What is a Good Resource Loading Time?

There is no one-size-fits-all answer to what constitutes a “good” Resource Loading score, as this can depend on a variety of factors, including the type of website, its content, and the target audience. 

However, here are some general guidelines to consider when evaluating Resource Loading performance for each of the optimization methods:

Page load time: a page load time of 2-3 seconds is a considered fast 

The number of requests: a lower number of requests can lead to faster page load times.

Page size: a good Resource Loading score would be to keep the page size under 2 MB 

Core web vitals: in addition to the above metric you should also monitor your websites performance against the core web vitals which are the 

First Input Delay 

Cumulative Layout Shift 

Largest Contentful Paint

Best practices for Resource Loading:

To ensure that your website is optimized for Resource Loading, it is important to follow best practices. Some of the best practices include:

1. Minimizing HTTP Requests:

One of the most effective ways to optimize Resource Loading is to minimize the number of HTTP requests that are made. Each HTTP request adds to the loading time of a page, so reducing the number of requests can significantly improve page speed. To minimize HTTP requests, you can use CSS sprites, combine multiple stylesheets into one, and optimize images by reducing their size and using the appropriate format.

2. Compression and Minification:

Compression and minification are techniques used to reduce the size of resources, such as stylesheets and scripts, which can result in faster loading times. Compression involves reducing the size of files by removing redundant information, while minification involves removing unnecessary whitespace, comments, and other elements from the code.

3. Caching and Preloading:

Caching involves storing frequently used resources on the user’s device so that they do not have to be reloaded every time the page is visited. Preloading involves loading resources in the background before they are actually needed so that they are available instantly when required. Both caching and preloading can significantly improve the speed of Resource Loading.

4. Async and Defer Attributes:

The async and defer attributes can be used to control the loading of resources on a page. The async attribute specifies that a resource should be loaded asynchronously, allowing the browser to continue rendering the page while the resources are being loaded. The defer attribute specifies that a resource should be loaded only after the page has finished parsing, ensuring that the resource does not block the rendering of the page. 

5. Lazy Loading:

Lazy loading is a technique in which resources are loaded only when they are needed, rather than loading all resources at once. This can significantly improve the loading speed of a page, especially for large and complex websites. Lazy loading can be implemented using JavaScript, allowing resources to be loaded only when they come into view, or as they are requested by the user.

6. Image Optimization:

Image optimization is another important aspect of Resource Loading. Large and unoptimized images can significantly slow down the loading speed of a page, so it is important to optimize images by reducing their size, using the appropriate format for example JPEG for photos, PNG for graphics, and compressing them if necessary.

Implementing best practices for Resource Loading is essential for optimizing the performance of your website and providing a better user experience. By reducing the number of requests, reducing the number of requests, minification, compression, etc.

While these optimizations can be done manually, they can be time-consuming and challenging to implement and maintain. Fortunately, there are tools like RabbitLoader available that can automate many of these optimizations for you, saving you time and effort while ensuring that your website is optimized for performance and provides the best possible user experience.

FAQs:

What are async and defer?

Async and defer are attributes that can be added to script tags in HTML to control the loading and execution of JavaScript files.

Async allows the script to be loaded and executed asynchronously, meaning that it does not block the loading of other resources or the rendering of the page. This can result in faster load times.

Defer is similar to async in that it allows the script to be loaded and executed asynchronously however unlike async, the defer attribute guarantees that the scripts marked as defer will be executed in the order in which they appear in the HTML.

Common Challenges and Solutions:

Despite following best practices for Resource Loading, there are still some common challenges that can arise, some of these challenges include:

1. High HTTP Request Count:

One of the most common challenges in Resource Loading is having a high number of HTTP requests. This can result in a slow-loading website and poor user experience, so it is important to minimize the number of requests by combining resources and optimizing images.

2. Blocking Resources:

Blocking resources, such as stylesheets, can slow down the loading of a page, as they must be loaded before the page can be displayed, to avoid this, it is important to optimize blocking resources by compressing and minifying them, as well as using the async or defer attributes to control their loading.

3. Large Resource Size:

Large resource sizes can also slow down the loading speed of a page, so it is important to optimize resources by compressing and minifying them, as well as using lazy loading and image optimization techniques.

Conclusion: 

In conclusion, Resource Loading is a crucial aspect of web development that plays a significant role in the user experience, SEO., and cross-device compatibility of a website. By following best practices for Resource Loading, and optimizing images, you can ensure that your website is optimized for fast and efficient Resource Loading. Additionally, by being aware of common challenges and solutions, you can troubleshoot any issues that may arise and ensure that your website runs smoothly and efficiently.

The Impact of First Input Delay on User Experience and How to Improve it

The user experience of a web page is critical to its success. It affects everything from the number of visitors to the conversion rates and overall satisfaction of the users with the site. One key performance metric that measures the user experience is First Input Delay.

What is First Input Delay?

First Input Delay (FID) is a critical performance metric that measures the responsiveness of a website, it is the time between when a user first interacts with a page (such as clicking a link) and when the browser is able to respond to that interaction.

A low First input Delay score is important for providing a good user experience, as it ensures that the website will respond quickly to user interactions. This leads to a higher level of user satisfaction and engagement.

According to WebPageTest’s latest statistics from February 2023, about 32% of websites have a first input delay (FID) of 100ms or more which means it needs serious improvements, these 32% of websites due to high FID scores give a bad user experience and overall bad SEO rankings.

We can get this number using the CrUX (chrome user experience) dataset and the BigQuery tool link to the dataset.

Significance of FID as an SEO (Search Engine Optimization) Keyword

The significance of First Input Delay (FID) as an SEO keyword lies in the fact that it is a crucial aspect of technical SEO and page speed. 

Technical SEO refers to the optimization of a website’s infrastructure and code to make it more easily crawlable and indexable by search engines. One of the key elements of SEO is page speed, which is the amount of time it takes for a page to load in a user’s browser. A slow page speed can lead to a poor user experience and a decrease in the website ranking in search engine results pages (SERPs).

How Does First Input Delay Work?

When a user interacts with a page, the browser must process the event, run any relevant JavaScript execution and update the DOM before it can respond to the interaction. The process can take time and the delay between the user interaction and the browser response is the First Input Delay.

FID is measured in milliseconds and is calculated as the time between the user interaction and when the browser is able to respond to it. The lower the First Input Delay value, the better the user experience.

A good First Input Delay score ensures that the website will respond quickly to user interactions, leading to a higher level of user satisfaction and engagement.

Factors Contributing to High First Input Delay Scores

Large JavaScript Files:

JavaScript code is essential for many dynamic and interactive elements on a website, such as forms, animations, and navigation. However, large JavaScript files can slow down the browser and increase the FID score. There are various ways to minimize the effect of JavaScript to lower the First Input Delay score which will be discussed in further sections.

Slow Server Response Times:

Slow server response times can also contribute to a high First Input Delay score, as the browser must wait for the server to respond before it can process the user interaction.

Complex DOM Updates:

The Document Object Model (DOM) is the structure of a web page and represents how the element on the page interact with each other. Updating the DOM can be slow and complex, especially if the updates are frequent or require more elements to change. This can in turn increase the FID.

Resource-Intensive Images and Videos:

Images and videos can take up a lot of resources and slow down the browser, large images and videos take longer to load adding the time it takes for the browser to respond to user interaction, this can lead to a slow and unresponsive experience to users, leading to a higher FID score. 

Third-Party Scripts:

Third-party scripts such as analytics and advertising, and social media, can also contribute to a high FID score. These scripts can add additional resources that must be loaded, processed, and executed before the browser can respond to user interaction. This can lead to longer response times and poor user experience. 

FAQs:

How is FID Measured?

Measuring First Input Delay is typically done by real-world testing using real users, by logging the time from when a user first interacts with the page to when the browser is able to respond and then testing its interactivity. The measurement tool for measuring the First Input Delay is usually google lighthouse.

What is a Good First Input Delay Score?

A good First Input Delay score is considered to be less than 100 milliseconds. A low FID score indicates that the website is responsive to user input and provides a smooth user experience. 

Optimizing FID 

Optimizing First Input Delay (FID) is crucial for improving user experience and website performance. The following are some of the practices for optimizing FID.

Minimize JavaScript and Other Resources : 

Reduce the amount of JavaScript tasks and other resources required to load a page to improve the time it takes for the browser to respond to user interactions. This can be achieved by combining and minifying JavaScript and CSS files, reducing the number of HTTP requests, and using resource-efficient images and videos, alternatively, tools like RabbitLoader can help minimize the amount of JavaScript required for page load automatically streamlining the process for you.

Reduce the Size of Large Files : 

Large files can significantly slow down a website and increase the FID time, by reducing the size of the files you can reduce the time it takes for the browser to respond to user interactions and improve FID. This can be done manually by compressing them or using more efficient file formats. Or RabbitLoader can help you optimize the size of these files automatically, ensuring that your pages load quickly and efficiently.

Minimize DOM Complexity : 

The more complex the Document Object Model (DOM) of a website, the longer it takes for the browser to process user interactions. To minimize DOM complexity, use techniques such as avoiding excessive nesting, reducing the number of elements on a page, and using CSS instead of JavaScript to manipulate DOM. this can be done manually or by tools like RabbitLoader which can update DOM automatically allowing for a faster and a more responsive experience for your user.

Implement Lazy Loading : 

Lazy loading is a technique that only loads resources such as images and videos when they are needed. This can significantly reduce the amount of data required to load a page and improve the time it takes for the browser to user interaction and reduce the First Input Delay time.

Minimizing Third-Party Scripts : 

Third-party scripts such as advertisements, analytics, and social media widgets can slow down a website and increase its First Input Delay time, To minimize the impact of third-party scripts manual optimization can be done by reducing the scripts used, implementing lazy loading, and using resource-efficient scripts. This can either be done manually or tools like RabbitLoader can automatically do this for you improving your website’s First Input Delay score.

Using Fast Hosting Solutions : 

A slow hosting solution can significantly impact the time it takes for a website to load and increase the time it takes for a website to load and increase the time it takes to respond to user interactions. To optimize FID, use a fast hosting solution with low latency and high bandwidth. 

Use a Content Delivery Network (CDN) : 

A Content Delivery Network (CDN) can improve the time it takes for a website to load by caching and serving content from multiple locations around the world. By using a CDN you can reduce the time it takes for the browser to respond to user interactions and improve the First input delay.

These optimization techniques can help you improve the performance of your website and reduce the First Input Delay (FID) to provide a better user experience. However, it is important to note that the First Input Delay is just one of several Core Web Vitals and to provide a high-quality user experience, its necessary to optimize all the web vitals including the Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Total Blocking Time (TBT).

Apart from these optimization methods, there are some other methods as well listed below, the below-listed methods revolve around implementing the above-mentioned methods. 

Defer Unused Scripts:

Any unused scripts should be deferred until they are needed. This can be achieved either by splitting large scripts into smaller ones or by using code splitting and loading scripts on demand. 

Minimize Main Thread Work: 

To minimize the main thread work, you can use lazy loading to defer the loading of images and other heavy resources until they are needed. 

Minimize DNS Lookups: 

A DNS lookup is the process of finding the IP address associated with a domain name. By reducing the number of DNS lookups, you can speed up your website’s load time. You can achieve this by reducing the number of third-party scripts and plugins used on your website.

Use Browser Caching: 

Browser caching allows your website to save frequently accessed resources to a cache, reducing the time required to load the resources. You can leverage browser caching by using expires headers, cache control headers, and ETags.  

FAQs:

What is Meant by Deferring?

Defer means the process of delaying the loading of a certain resource, such as a JavaScript file until it is needed. By deferring the loading of non-critical resources, it reduces the amount of JavaScript that needs to be parsed and executed during page load, resulting in faster page load times and a good First Input Delay score.

What is a DNS Lookup?

DNS lookup is the process of resolving a domain name to its corresponding IP address. When a user enters a website’s domain name into their browser, the browser sends a request to a DNS server to resolve the domain name to its IP address. The IP address is then used to access the website’s server, where the website is hosted. This is an essential part of the process of accessing a website as it allows the browser to find and connect to the correct server hosting the website.

What is the Core Web Vital?

Core Web Vitals are a set of metrics defined by Google that measure the quality of user experience on websites. They include 3 main aspects: loading speed, interactivity and visual stability the Core Web Vitals metrics are: 

Largest Contentful Paint (LCP)

First Input Delay (FID)

Cumulative Layout Shift (CLS)

What is the Largest Contentful Paint (LCP)?

Largest Contentful Paint (LCP) is a web performance metric that measures the loading performance of a page. It specifically measures the time taken for the largest element visible within the viewport ( such as an image or text block ) to fully load and become visible to the user. LCP is one of the three core web vital metrics.

What is Cumulative Layout Shift (CLS)?

Cumulative Layout Shift (CLS) is a metric that measures the visual stability of a website. It is one of the three Core Web Vitals.

 CLS measures the amount of unexpected movement of page content, such as images or text, while the page is loading, this movement can cause the users to accidentally click on the wrong element, which can have a negative impact on the overall user experience, the goal should be to have CLS score of 0, indicating no unexpected movement which leads to smoother user experience. 

What is Total Blocking Time (TBT)?

Total Blocking Time (TBT) is a performance metric that measures the total amount of time a page is blocked from responding to user input, such as scrolling or clicking links, TBT is expressed in milliseconds and is calculated as the sum of all periods of time and where the browsers main thread of the page was blocked for more than 50 milliseconds. 

This metric is an important factor in determining the overall user experience of a website, as it measures the interactivity of the page and how quickly it can respond to them. Higher the TBT score the more negative the impact on the user experience and leading to a lower conversion rate and decreased traffic to a website. 

Google’s Core Web Vital is monitored by using various tools and techniques, including google analytics and google page speed insights. 

Google Analytics can track and report on the user experience metrics of a website, including core web vital, this allows website owners and developers to monitor the performance of their site and identify areas for improvement.

PageSpeed insight is a tool that analyzes the performance of a website and provides recommendations for optimization. It also reports on the core web vital for a given page.

In addition to page speed insight and google analytics, developers can use a variety of performance monitoring, real user monitoring, and testing tools to measure the core web vital and identify areas for optimization. By monitoring these key performance metrics, website owners and developers can ensure that their sites provide the best possible user experience.

Conclusion

In conclusion, optimizing First Input Delay (FID) is crucial for providing a great user experience and improving the overall performance of a websites FID, along with other googles Core Web Vitals, are important indicators of a websites page experience and are increasingly being used by google to rank websites in google search results by google page experience.

 Utilizing tools like google page speed insights, google lighthouse, and google analytics, websites can reduce their First Input Delay scores and improve the performance and user experience for real users.

By providing a responsive and fast website, businesses can not only improve user satisfaction and engagement but also boost their visibility on google searches and achieve better conversion rates. Overall paying attention to FID is an important aspect of website optimization and should not be overlooked.
