First, let’s look at the reasons why WP Rocket is the best caching plugin that most WordPress users trust.

Caching is the process of caching static page elements to speed up subsequent visits. When a user visits your website for the first time, the page is loaded from the server and uses some server resources. However, the default working mechanism can consume a lot of system resources and even slow down the page loading speed.

WP Rocket will create a cached version of the page and the system will use this version to serve the user on subsequent visits. This dramatically increases speed and conserves resources. Additionally, this plugin adds Cache control headers to static resources to make HTTP caching more efficient. Additionally, the header also allows page preloading on hover. This helps optimize load times and improve page performance on future visits.

Benefits of page speed

First, users will definitely prefer to visit pages with faster loading speed. No one wants to wait tens of seconds or even minutes just to wait for a webpage to load.

Second, the fast page loading speed also brings certain benefits to website owners. After achieving a high page load speed, we will have more opportunities to interact with users, thus easily implementing the online business strategies mentioned earlier.

Finally, page load speed has a significant effect on a website’s ranking. This is the official ranking factor announced by Google, so make sure you have strategies in place to increase your site speed.
