8 Best WordPress Caching Plugins to Speed Up WordPress Website

Some time has passed since Google announced that the speed with which the site loads will affect the position on the SERP. The same applies to mobile devices. But most of all you should worry about how the slow website will affect users. 

For example, are you aware that half of visitors to sites on the Internet think that it should load in two seconds or less? I think this is very fair, because if you think so, then there is nothing more annoying than watching how something is loaded. 

Not to mention the inconvenience a person experiences when he wants to buy something, and the site is slow.

Fortunately, there are many ways you can speed up your site. One of the best options is to use a special module for caching (cache). 

Good website speed can boost traffic to your website.

Today we will briefly review what caching is and why it is so critical when it comes to page loading speed. In addition to this, I will also share with you a list of the best cache plugins on the market.

What is cache?

A cache is a place in computer memory where data is stored for future use. For example, instead of fully executing the process of loading a site from a database, some of the data is pumped from the cache. 

When a visitor walks around your site, the site requests data from a database that is stored on the hosting. 

To be more precise, they request images, Javascript and CSS of your site so that it is in readable HTML files and delivered directly to the browser. Unfortunately, this process requires certain resources and takes time. 

However, there is no need for site users to have to start this process each time. Especially when it comes to the static content of your site. For example, published posts that are unlikely to be edited by anyone.

That is why caching your site is necessary if you want:

  • quickly provide access to site data that rarely changes
  • speed up the whole process of loading the site
  • provide a better user experience for all visitors to your site
  • promote in search engine SERPs, thanks to higher download rates
  • save server resources and reduce the number of crashes

As you can see, there are tons of benefits to caching your WordPress site.

The main functionality that is in each of the mentioned plugins:

  • caching for mobile users
  • file size reduction and gzip compression
  • setting cache clearing schedule
  • HTTPS / SSL support
