How to Leverage Browser Caching in WordPress via .htaccess

One of the best ways to improve the speed and performance of your WordPress site is to leverage browser caching.

By leveraging browser caching, you can reduce the number of HTTP requests that the server needs to process, thus reducing loading times and improving website performance. And as an added bonus, when you leverage browser caching, you improve your scores on Core Web Vitals and other pagespeed tools!

In order to leverage browser caching appropriately, you need to modify the .htaccess file for your site.

Finding and Modifying .htaccess

While it may seem daunting, modifying the .htaccess file is quite simple. You can access your .htaccess file through cPanel by clicking on the File Manager. Make sure you are in the web root folder and that you have the “Show hidden files” option toggled on.

If you don’t have cPanel, you can simply create a new .htaccess file in the root of your WordPress install. The root folder is the same folder where the wp-config.php file is found.

Pasting in the Directives to Leverage Browser Caching

Open up your .htaccess file and paste in the following directives at the top of the file:

<IfModule mod_expires.c>
	FileETag MTime Size
	AddOutputFilterByType DEFLATE text/plain text/html text/xml text/css application/xml application/xhtml+xml application/rss+xml application/javascript application/x-javascript
