Are you ready to boost the speed of your WordPress website with minimal effort?

If so, you need to choose from one of the best caching plugins in the market. Using a WordPress cache plugin is one of the most effective ways to ensure your website loads blazing fast and your visitors enjoy exploring your site.

Today we’re going to share with you the best WordPress cache plugins around so you can speed things up instantly.

After all, site visitors expect websites to load in 2 seconds or less. And 40% of people will abandon your site if it takes longer than 3 seconds to load.

With such as easy solution like adding a caching plugin to your website, there is no excuse to give your site’s loading time a bump.

To help you out, here’s a convenient table of contents so you can quickly jump to the section (or solution) you want:

What is Cache?

When a site visitor clicks on your website, your site sends a request to your server. This request asks the server to deliver your site’s content to the site visitor’s browser so they can see it.

The problem is, your web server has to process these requests every single time someone clicks on your website.

And this takes time.

If your website is popular and has a lot of traffic, your server has to work extra hard to continue processing requests and delivering your site’s content to browsers all over the world. This means your website has the potential to slow down.

When you use a WordPress caching plugin, it tells your server to store a copy of some of your site’s files to disk or RAM (depending on how it’s configured). This is called the cache. When a site visitor that has accessed your site in the past returns, the content is served up from the cache immediately. This equates to faster loading times and a better user experience.

Why Use a WordPress Cache Plugin

There are plenty of benefits for using a WordPress caching plugin on your website:

  • Faster loading times. When you use one of the WordPress caching plugins on our list, your site’s content is delivered instantly to return visitors. Because of this, you’ll boost conversions, a lower bounce rate, and better search rankings too.
  • Improve the user experience. When you increase your site’s loading times, people have a more enjoyable experience while exploring your site.
  • Less server strain. Instead of making multiple requests to your server every time a repeat visitor comes to your website, a caching plugin saves the site data and files in the cache. This means you use less server resources and decrease the server strain. This is important if you run a dynamic website such as a membership or eCommerce shop.

01. W3 Total Cache

Note: BoldGrid recently acquired the plugin, so you can expect more regular updates & support.

W3 Total Cache aims to improve your SEO, the user experience, and site performance. It does this by caching everything on your website and integrating with your content delivery network. Better yet, it accommodates all hosting environments, from shared hosting to dedicated hosting environments.

This WordPress cache plugin offers support for Google Accelerated Mobile Pages (AMP) and Secure Socket Layer (SSL). This makes it an ideal solution for those with eCommerce sites and other websites with dynamic content that not only needs caching, but increased security too.

In addition, it comes with GZIP compression to optimize web browser rendering, which is just another way to speed things up.

02. WP Super Cache

WP Super Cache is another one of the best WordPress caching plugins in the repository that serves static HTML files from your dynamic (ever-changing) WordPress blog.

This is done instead of processing PHP scripts, which strain your server, use up more resources, and slow your website down. The static files that are generated and stored in the cache will deliver to users that are not logged in, users that have not left a comment on your site, and even those that have not viewed a password protected post.

This caching plugin is great for compressing pages, cache rebuilding, and supporting your existing CDN.

Plus, it comes with intelligent caching so those who need cached content delivered get it, and those that don’t – don’t.

Lastly, this caching plugin comes with a neat feature called garbage collecting. As you cache your site’s content, the cache gets full.

However, WP Super Cache automatically cleans out the cache on a regular basis so your site continues to load fast.

  • It was created by Automattic, so you know it’s updated regularly and won’t disappear
  • Most backend settings are pre-populated
  • Cache rebuilding feature means your cache isn’t cleared when someone leaves a comment

Comet Cache is a caching plugin that takes a real-time snapshot of every page, post, category, link, and more and stores them in the cache. From there, the plugin decides which site visitors to deliver cached content to, and which ones to deliver fresh new content to.

By default, Comet Cache does not serve cached pages to users who are logged in or users who have recently left comments on your site. It also excludes admin and login pages.

This intuitive plugin allows you to control the automatic clearing behavior on homepages, posts, author pages, categories, tags, and even XML sitemaps.

Plus, it caches RSS feeds and 404 requests.

It also serves cached files on your site from a content delivery network (CDN). Lastly, to avoid generating a new version of the cache while your server is busy, the plugin will monitor the server load and disable the cache expiration temporarily.
