Are you looking for a Content Delivery Network (CDN) for images to speed up your WordPress website?

However, converting and compressing images can only achieve so much. To improve your website’s loading speed to an optimal level, it is equally important to serve the images on your website through a CDN network to reduce the loading time of your website.

Most website owners and SEO experts spend a lot of time researching and choosing a reliable Content Delivery Network (CDN). To save valuable time, we will list 5 reliable CDN plugins available in the WordPress ecosystem. 

Finally, we will wrap up by discussing how using RabbitLoader instead of just a CDN plugin would benefit your website’s overall performance.  

What Is A Content Delivery Network (CDN)?

A CDN (Content Delivery Network) is a group of proxy servers distributed worldwide, also known as PoPs (Point of Presence). 

The main purpose of using a CDN is to reduce the physical or geographical distance of the users from the servers and reduce the network latency. 

CDN

When a visitor loads a web page, in the absence of a CDN cache the browser usually generates an HTTP request and sends it to the origin server. If the physical distance between the users and the server is high, it will take more time to load the resource files for rendering the web page. This delay is known as network latency. 

A CDN network distributes the website’s resource files among its PoPs (point of presence). In the case of a CDN-integrated WordPress website, the browser sends the request to the nearest proxy server instead of the origin server (hosting). 

Thus, it will minimize the distance between users and servers, reducing network latency and improving the WordPress website’s loading time and PageSpeed performance. 

Which Resource Files Can Be Cached In A CDN? 

There are 4 types of resource files which can be cached in a CDN. 

  1. Images
  2. HTML file
  3. CSS files
  4. JavaScript files

There are many CDN providers available on the internet, but integrating them with your website might not be everyone’s cup of tea. Hence, we will mainly focus on the WordPress CDN plugins as they are by far the most convenient option for most WordPress admins

Why Is CDN needed for Image optimization? 

There are three main reasons for using a Content Delivery Network for image optimization. It is more like a domino effect, where adding CDN causes subsequent outcomes. 

  • Using CDN improves the website’s performance 
  • A fast-loading website enhances the user experience 
  • A fast-loading website is good for organic Rankings

Using CDN Improves Website’s Performance 

A proxy server acts as an intermediator between the user and the origin server. Hence, it would reduce the network latency which improves the response time of your WordPress website by improving the PageSpeed performance, a CDN also improves the website’s security protecting you from DDoS and other cyber attacks by not exposing your server address

A Fast-Loading Website Enhances The User Experience 

Regardless of the physical location of the users, they expect a fast-loading website. 

Using a CDN service would reduce the physical distance between users and the resource files a visitor is trying to load, thus reducing the response time so the visitor does not experience any delays when loading the web page. 

Since loading time creates the user’s first impression of your WordPress website, providing a fast-loading website can present a high-quality user experience and increase the average on-page time by allowing users to engage with your website’s content without any obstructions or delays. This leads to reducing the bounce rate and improving the conversion rate.

A fast-loading website is good for organic Rankings 

Since PageSpeed is considered a major ranking single, improving it gives you a leg up in today’s very competitive organic ranking race. 

Using a Content Delivery Network (CDN) improves the PageSpeed performance of a WordPress website to an optimal level, which leads to improving the page’s ranking in the Search Engine Result Pages (SERPs). This, in turn, can increase the organic traffic of your WordPress website.

Can You Optimize Images Without a CDN?

As a WordPress website owner, you may be wondering: Is it possible to optimize images on a WordPress website without using a Content Delivery Network? 

The answer is “Yes.” There are several ways to optimize your WordPress images: converting them into next-gen formats, compressing them, resizing them, and implementing lazy loading

Note: The above image optimization techniques require a fair amount of time, patience, and effort if you want to Do It yourself without using any image optimization plugin. The best way to install RabbitLoader which can improve the PageSpeed performance within a few clicks.  

The above image optimization techniques are effective when the user’s location is closer to the origin server. However, they can’t reduce the physical distance between the user and the origin server. If the distance between the user and the server is high, it will take more time to load the file regardless if the images are optimized or not. 

You must use an image CDN to quickly load the images on the WordPress website from the user’s browser for the best result even if you are optimizing your images in other ways.
