4 Best WordPress Caching Plugins for 2020 (Compared ) – Boost Your Website Speed


I hear people talking about the loading speeds of their websites a lot. Also, I have encountered lots of people wondering how to clear cache in WordPress and boost their website speed. After all, the internet has become all about speed today. Here, if your site takes time to load then in no time your visitors will switch to another one. Does this situation sound familiar???

Well, there are various ways to get your website optimized for speed. Your choice of WordPress hosting determines the speed of your WP site in a great deal. Remarkably, most of the best WP hosting providers come with an in-built caching (super-cacher) feature which is surely a good point. However, it would be far better if you yourself take care of caching by installing a WordPress clear cache plugin. 

So, I present you the list of best WordPress cache plugins to help you improve your site’s speed. Also, I have compared and evaluated each one of them for your convenience. With the greatest reviews and highest numbers of active installs, these plugins are proven to help you get rid of the excessive loading times. Eventually, saving you from losing your global potential visitors and the Google search ranking, of course.

But before we jump into the descriptions of the individual plugins, why not have a quick look at their comparison table?? 😉
