Cache vs Cookies: Which One Impacts Your Browsing Experience More?

Cache and cookies serve purposes in enhancing websites performance and tailoring user experiences. Cache accelerates page loading times, by storing web content in the browser and on the edge servers. On the other hand, cookies simplify tracking user preferences and interests through the retention of personalized data such as web pages and browsing session specifics.

Cache vs cookie

What is Cache?

A cache is a temporary storage location that is used to store copies of static files like CSS, JavaScript, and images in order to load the website quickly.


This is a one-way relationship. That indicates the files that are already stored in a cache, don’t go back to the server.

What are Cookies?

Cookies are small files of information that are generated in a web server and put on a user’s computer. Cookies are used to store only text-based data like visit histories, IP addresses, session IDs, and so on.


This is a two-way relationship, where a server can read the information from web cookies.

Cache vs Cookies: Why are they used 

Probably you have some idea about the difference between Cache vs Cookies. But, let us cover this topic in more detail for a better understanding of the difference between Cache vs Cookies.

Starting from the beginning, your website has a large number of static resources like CSS, JavaScript, images, videos, and many more that won’t change for a long time. Browser cache is used to store certain static files to speed up your website.

Two types of caching are mostly used to speed up a webpage.

  • Browser Caching:

A browser caching is used to temporarily store the recently used web pages and data in a web browser. It is used to increase the website’s speed by locally downloading the component of the webpage in the browser cache.

  • Proxy Server Caching: 

A proxy server caching is a technique used by the proxy server to store copies of statics resources like CSS stylesheets, JavaScript files, images, and so on. When a user requests web pages or files, the proxy server provides the cache version instead of fetching it from the original server, which may increase the loading time.

Where Cookies are text-based small files that are used to store information that is unique for each visitor. It is also used to identify and track a visitor. Cookies provide a better user experience. 

There are various types of cookies:

  1. Session Cookies:

A session cookie is a simple small-sized text file that a website installs in a user device for use temporarily. session cookies are used to help a website track a user’s session. When users log out of their account or exit the website, Session cookies are automatically deleted.

Cache vs Cookies: Impact on Page Load Times/ PageSpeed

Now, you already have an idea of the difference between cache vs cookies. As there is a huge difference between cache vs cookies, so they play different roles on the website.

 PageSpeed is defined as the length of time taken to render all content of the webpage. Google has over 200 estimated SEO tracking signals, among which a few are confirmed, pagespeed is one of the confirmed ranking signals.

Now you can see the impact of the page loading time of cache vs cookies.

  • The Impact of Caching on Web Page Loading Time

Caching plays a crucial role in increasing the web page loading time. When a user visits a web page, usually, the browser fetches the content including HTML, CSS, JavaScript files, and images from the original server. This is a time-consuming process.

The impact of cache page load time

Caching helps you to reduce this web page loading time by storing the statics resources on the user’s device or any proxy server closer to the user’s location. When the user re-visits the webpage, then the browser fetches the content from the cache instead of downloading it from the original server.

However, it’s important to manage the cache to make sure that cache resources do not become stale and that users receive the most updated content.

  • The Impact of Cookies on Web Page Loading Time

Cookies are mainly used to remember browsing information like login information, user preferences, and many more. Cookies also can impact the web page loading time. It stores the session information. This can help to improve the web pageSpeed by reducing the need for frequent server requests.   

Impact of cookie on page load time

However, cookies can harm web performance as well as Search Engine Optimization (SEO) rankings. When the webpage has a large number of cookies or a cookie contains a huge amount of data, it can increase the number of requests and responses. So, loading time will increase. 

Especially when cookies initiate some external server request, as with tracking cookies, the loading speed of web pages will significantly drop. 

How to reduce cookies and optimize web performance

Now, already you know how cookies can negatively impact the website’s pagespeed. To optimize cookies for better performance we need to follow some strategies.

  1. Use Cookie-Free Domains:

You can reduce cookie usage by using cookie-free domains for serving static resources like CSS stylesheets, JavaScript files, images, and so on from local storage. Also, you can use browser caching and Content Delivery Network (CDN) services to improve pagespeed.

  1. Minimize the Cookie’s Size and Scope:

One way to minimize cookie usage is to reduce the size and scope of the cookie. For example, you can store only essential data, such as Session ID, and authentication token instead of user profiles.

  1. Use HTTP Headers or JavaScript:

Another way you can reduce cookie usage is by using HTTP headers or JavaScript files to send the data to the server instead of using cookies.HTTP headers can be used to transmit information such as content type, authentication, etc.

  1. Use HTTP Cache:

 HTTP is another way to improve load performance. It reduces unnecessary requests. HTTP requests are first checked in the browser cache whether they match or not. If it matches, then the response can be read from the browser cache. This reduces the network latency.
