There have been many articles written on WordPress caching plugins. They explain what caching is, why you need caching and which plugin does the best job at speeding up your site. Most of these articles are very interesting to a geek like me and if you’d like to read the technical stuff, see the links at the bottom of this article. The purpose of this article is to explain why I use WP Rocket for my caching solution.
Easy to use – Unless I am maintaining the site for my customer, they need a caching plugin that is easy to setup and use. I prefer this myself as I don’t have time to be messing about with advanced settings to get every ounce of speed out of my site. If that’s important to you, then consider W3 Total Cache.
Performance – Many others have done comparison tests on the top caching plugins. WP Rocket comes out on top nearly every time.
Cost – If you must use free, then consider WP Super Cache, which comes in the top three in performance in most tests. While WP Rocket costs $49 per year (at the time of this publication), it is 50% ($24.50 thereafter) for one site. They have a 5 site and unlimited package as well.
