Caching is the process of storing data so that it can be retrieved more quickly. When web browsers make requests for web pages, the browser will remember what was requested in the past and store it in a local cache.

That is why WordPress Cache plugins are essential for optimizing and increasing the speed of your website or blog.

Caching plugins are necessary for websites as caching will reduce load time by storing copies of files locally on your computer or server. These files can then be quickly served up to users instead of generating them from scratch every time a user visits your site.

If you're looking for the best cache plugins for your WordPress website, you're at the right place.

In this article, I have highlighted and compared some of the best WordPress cache plugins that can boost your website speed and improve your Core Web Vitals which is an important ranking factor on search engines.
