What is a Cache Plugin for WordPress?

Before we start with the list of the best cache plugins for WordPress, let’s be clear about what cache is and how these plugins work.

When you browse the Internet, what you’re doing is downloading information to your device from a computer (or server in this case). In WordPress, pages are generated through hundreds of PHP scripts, which means a lot of data movement is happening between the server and the client.

But in principle, this is not a problem, as long as your page does not receive a large number of visits. But if you start generating traffic (and you don’t use a quality server) you can saturate it.

What WordPress cache plugins do is save all the pages that are generated the first time someone enters. In addition, it stores them in HTML format in the cache to display them from there, which significantly reduces the loading time.
