What is Cache? Why Do You Need Caching in WordPress?

 A cache is a collection of temporary data that is stored in a reserved location so that it helps websites, browsers, and apps to load faster. You can find varieties of caches whether it’s a computer, mobile, web browser, or app.

What is Website Speed
Boost Website Speed

Normally, when a user visits your WordPress site, a web browser fetches information from the database. It runs through different steps before it sends that information to the user’s browser.

Such a process seems to be tedious and can sometimes make your website load slower. This same thing can get worse if lots of users are visiting your website at the same time. 

Thankfully, the cache makes it very much easier to retrieve information quickly and makes sure that it helps your site load faster. It acts as a memory bank from which users can access frequently accessed data locally without having to re-download it from the server. 

WordPress caching works just that way! Here, WordPress generates static HTML pages of your website and saves them on your server. So that each time when a user tries to access your website, it’ll serve up the light HTML version instead of heavy PHP scripts. Hence, this will tremendously improve the page loading time of your website.

Now let’s look at some of the best WordPress cache plugins.
