Let’s start with this: What exactly is caching?
That sounds like a lot, right?
So what caching does is save a lot of this stuff on the server’s disk or memory so that it doesn’t have to pull it every time someone requests a page. That’s what WordPress caching is, in a nutshell.
Why should you care?
Because caching makes your site faster. And Google loves fast sites. It is a ranking factor now, so it’s not something to be ignored.
But not only that, it’s important because your users are not going to wait around for your site to load. People expect your site to load in 2-3 seconds. That’s a high expectation!
How do I do it?
There are a lot of ways to enable caching for a WordPress site. There are a number of free plugins to try.
These have varying levels of difficulty setting up. W3Total Cache has the most active installs, but probably has a steeper learning curve then others.
Of course, there’s always premium caching plugins too. I really like WP Rocket. It’s easy to install, works well, and is affordable. It’s no secret that I’m a sucker for a premium plugin, so I use WP Rocket on my site and on sites I create.
