Best WordPress Caching Plugins 2018

There are so many candidates for being the best WordPress Caching plugin in 2018.

In this article, I will try my best to narrow down the list for you.

There are a couple of reasons why you should use WordPress caching plugin to speed up your WordPress website.

Two of the most important ones are because it affects the user experience and your SEO ranking.

Firstly, statistics says that if your website takes longer than 3 seconds to load then the visitor will abandon.

Another is if Google detects that your website takes a lot of time to load then it would punish your SEO ranking.

I guess we could all agree that nobody likes a slow loading website.

Fortunately, there are WordPress caching plugins that could speed up your website by simply enabling its features.

Before we get into the list, let’s first find out how the WordPress caching plugin works.
