8 Best WordPress Cache Plugins to Speed Up Your Website

The cache is an integral part of website performance. Having a fast-loading website with minimal content breaks will make your visitors happier and more likely to revisit your site. Many different cache plugins are available for WordPress, so it can be difficult to know which one is best for you.

What is Website Loading Time?

Loading time is the amount of time taking by a webpage to completely load up in your browser. It is mainly affected by three things: your hosting provider, page size, and types of files being delivered.

Factors Affecting Websites Speed

  • Your hosting provider might not deliver proper speed and performance to handle your website.
  • Plugins or any code added inside your website can affect the speed. 
  • If your page has a lot of scripts, images or other files that might take time to load up completely.
  • Poorly optimized images. Images can contribute to around 80% to 90% towards page loading time. If you are using an image that is too large or has a low quality, it will take more time for them to load up.

Tips to load website faster

Fast loading speed is important to show visitors that you are concerned about their time. If they feel that your website takes too long to load up, they might just leave it.

Here are some tips and tricks to improve your website speed:

  • Choose a quality hosting and configure it properly to get optimal speed.
  • If your hosting provider offers caching services, use them.
  • Deactivate all the plugins that are not being used by your website.
  • Add a CDN in your hosting plan to decrease the load on your server, or you can use an external CDN such as Cloudflare.
  • Keep your website size small by removing or deactivating all the files that are not necessary.
  • You can use a good cache plugin to improve poor speed and performance.
  • Cache plugins may not be compatible with all themes and plugins, so check carefully before proceeding with an installation.
  • Minify CSS, JS, and HTML files and optimize images to load faster.
  • Remember to test the Website on Page speed tool before going live!

What are Cache Plugins?

The cache is a collection of temporarily stored data for quick access upon request. Cache plugins are very important because they help to make websites load faster. A cache plugin works by creating copies of static HTML files and storing them on the server, which means that instead of processing every page request, it simply serves up a cached version. As you can see, this is extremely useful for speeding up your website because there is no need to load all of your plugins with every page request.

There are two types of caching: page caching and object/database caching. They both work under different conditions to achieve maximum performance.

Page caching works by saving a static version of a web page and delivering that to the viewer. This reduces load time considerably.

Object or database caching stores data in memory faster than saving it to disk.

Importance of Utilizing a Cache Plugin

Many times, web hosts will cache your WordPress site for you. This is not the case with all hosting companies, though; some of them won’t do it by default. If your host does not have this enabled on their end, there are many WordPress caching plugins available that you can install to improve caching on your own.

Cache plugins are not only useful for speeding up your website; they also act as an additional layer of security to prevent hackers from accessing sensitive data. They can easily be used alongside other types of plugins (such as malware scanners) to keep your site running smoothly without sacrificing anything!

The plugin serves cached files in 3 ways:

  • Expert – The fastest method is by using Apache mod_rewrite (or whatever similar module your web server supports) to serve “supercached” static html files. This completely bypasses PHP and is extremely quick.

  • WP-Cache caching – This is mainly used to cache pages for known users, URLs with parameters and feeds. Known users are logged in users, visitors who leave comments, or those who should be shown custom per-user data. It’s the most flexible caching method and slightly slower. 


  • Support for multiple caching types (Mod_Rewrite, PHP, and Legacy)
