How to optimize WordPress with WP Rocket

As your site traffic increases and you add additional content, your site may begin to slow down because WordPress has to recompile a page every time a visitor accesses it. By utilizing caching and enabling additional optimizations, you can reduce the amount of work WordPress has to do for each page load, which in turn speeds up your site.

With the WP Rocket plugin, you can enable caching and many other optimizations for a WordPress site.

  • You must install WordPress on your site before you can install the WP Rocket plugin. For information about how to install WordPress, please see this article.
  • You must purchase a WP Rocket license before you can follow the procedures in this article. To do this, please visit
  • WP Rocket is incompatible with other caching plugins like WP Super Cache and W3 Total Cache. If you have one of these plugins installed, you must deactivate it before you activate WP Rocket for your site.

Installing WP Rocket

To install the WP Rocket plugin, follow these steps:

  1. After you purchase a WP Rocket license, download the plugin .zip file to your local computer.

Configuring WP Rocket

After you install and activate the WP Rocket plugin, it enables the following features:

  • Gzip compression.
  • HTTP header management.

  1. Log in to your WordPress site as the administrator.
  2. In the left-hand pane, click Settings, and then click WP Rocket.
