In this blog post, we will discuss the 5 best WordPress caching plugins for your website.

Before we discuss the best WordPress caching plugins, let’s first understand what is a cache.

What is Cache?

The cache is a set of temporarily stored data that can be accessed instantly on a request. In computers, data is generally stored on a hard drive. While a piece of information is requested, a computer needs to go through various processes before the information is presented to the end-user.

Caching resolves the issue by processing commonly requested information and later store it into temporary storage. This lets the computer access the files swiftly.

A similar caching concept can be utilized by WordPress sites to enhance the performance and make your WordPress website load faster.

How WordPress Caching Works?

As WordPress is a dynamic content management system, every time a user visits your site, WordPress fetches data from the database and then executes various other steps before a web page is sent to the user’s browser.

While several users visit your website concurrently, the whole process will reduce the speed of your WordPress website.

This is where caching is helpful. With caching several processing steps will be skipped. Rather than going through a full-page generation process each time, the cache plugin makes a clone of the page on the first load and offers the cached version to every subsequent user.
