Do you want to know how to clear your browser cache and why it’s important? Hint: If you have encountered an issue with your WordPress site, one of the easy solutions may be to clear your cache! In this guide, you’ll learn more about browser caching and how to clear each browser’s cache (and cookies). 

Let’s dive in!

What’s Browser Cache?

A browser cache stores files and resources downloaded directly from a website, such as media assets, text, and coding files (HTML, CSS, and JavaScript). Built into your web browser, the cache is a database that “memorizes” web content. 

Why Browser Cache Is Important

Browser cache allows content to be served faster to users that have already visited your website. It saves users time and reduces page loading time and web server bandwidth.

This is crucial for performance and the user experience because cached content loads faster than regular content: your browser doesn’t have to load everything from scratch.

For example, the server could tell the browser to store the payment method images and not download them when a user returns: 

Those images are unlikely to change daily so you could cache them for at least a week.  

Using WP Rocket to Enable Browser Cache

To enable browser caching, you can use WP Rocket – one of the best caching plugins for WordPress. The plugin requests the browser to save the frequently used (but rarely updated) files in its local cache memory, resulting in a faster experience for visitors. 

All you need to do is to install and activate the plugin. WP Rocket will do the heavy lifting and smartly set expiration lengths on the less updated files. 

You’ve learned the meaning of browser caching and how to implement it, let’s explain why it’s important to clear your browser cache as a user. 

Why You Should Clear Your Browser Cache

It’s important to clear your browser cache to avoid seeing outdated content and to solve most of the common problems on the internet – for instance, “issue 403”, nonce issues, and any development made in a local environment (if you don’t clear your cache, you may not see the updated content when you push it from the development environment to production).

We can take the example of a new banner you added but can’t see this change on the front end yet. That’s because your browser is still showing the cached version of the page with the old banner. By clearing your cache, you’ll finally see it when refreshing the page. 

Remember that a browser stores the cached content for a limited time or until it’s full. After that, the cache is cleared, and the browser will serve the updated content on the next visit.

You can also clear your cookies on a computer to protect your privacy and avoid third-party tracking.

The next section shows you how to delete cookies and clear your cache from the major browsers.

How to Clear Cache and Cookies on Your Browser

You can clear your browser cache and cookies manually on every major browser. To help you with this process, we have put together some easy tutorials for the most popular ones.

How to Clear Cache on Google Chrome

To clear the cache on Google Chrome, click the three dots icon in the top right corner of the browser window, then open the More Tools option and select Clear Browsing Data from the submenu. 

You can choose to clear the basic tab with the browsing history, cookies, cached images, and files by clicking on the Clear data button.

If you want to go further, you can open the Advanced tab and check the boxes of your choice. Note that if you decide to clear the cache of the Passwords and other sign-in data categories, then you will lose all your saved password for each website you have an account for. That may hurt your user experience for future purchases and connections.

When clearing your cache, you can also decide if you want to clear what happened in the last hour, 24 hours, 7 days, 4 weeks, and All time. If you want to clear everything since the beginning of your browsing history, click on “All time”. 

To clear cookies and other site data, you can go to Google Chrome Settings > Privacy and Security > Cookies and other site data:

It’s important to clear the cache of your browser but make sure you find the right balance between privacy and user experience. Having your sign-in and password saved in Google Chrome can be very handy to accelerate your online shopping experience.

A browser cache takes content such as text and images from the websites you visit and saves them in a database for your next visit. As a result, browser caching improves your page load times and enhances the user experience.
