5 Best Caching Plugins for WordPress [2024]

Table of Contents

Are you looking for the best caching plugin for your WordPress website?

Caching helps improve your website’s speed and page performance, which in turn results in improved page rankings on Google Search results, thus improving the overall SEO of the website.

There are many caching plugins out there that you can use on your website. To help you choose the best out of many, we have shortlisted the 5 best caching plugins.

Before we dive into the caching plugins, let’s understand what caching is and its benefits for your WordPress website.

What is Caching?

Caching can be complicated for some, while at the same time, it may look boring to others. To understand what Caching is, let us first understand how a request sent to a server gets rendered and displayed as a webpage.

Whenever you visit a webpage, it sends a request to the server. The server then processes that request (including database queries) and renders the webpage to your web browser. Let us say, for example, your site contains a header image, a few service and feature sections, and a footer at the bottom. So, the server has to process the request to render all of these sections and deliver them to the user’s web browser. In the case of huge websites, this might take some time.

This is where Caching comes into play!

In very basic terms, “Caching” means storing “some information” in a temporary storage area so that it can be retrieved later easily. A WordPress Caching plugin instructs your server to store some information on RAM or disk, depending on the configuration of the server. This helps in easily duplicating and rendering the information from cache instead of processing a request all over again, thus resulting in faster loading of a webpage. Therefore, using a WordPress Caching plugin helps improve the page load time of your website. 

Types of Caching

Page Caching is the most commonly used type of caching for WordPress websites. Page Caching is where a site stores a static HTML version of the page instead of building each page dynamically with PHP and database queries like WordPress usually does.

Some other types of Caching that WordPress plugins offer are:

  • Browser Caching: As the name suggests, browser caching means storing files on the browser for quick rendering.
  • Database Caching: In database caching, most common WordPress queries, such as getting a list of posts to be displayed on a particular page, are cached to avoid repetitive database queries.
  • Object Caching: In object caching, a collection of files such as documents, scripts, and images are stored locally to improve the page load time.

Benefits of Caching

  • Improve Speed: As we have constantly discussed in this article, caching reduces the page load time of your website, thus improving the speed of your WordPress website.
  • Improve User Experience: Now that your website’s speed has improved due to caching, users who visit your site can easily browse around it. A faster website will also help decrease a page’s bounce rate.
  • SEO improvement: A website with improved speed and a great UX will automatically result in increased page rankings from Google, thus improving its overall SEO.
  • Low TTFB: Most cache optimizations are done on the front end. However, server-side optimizations are equally important when improving your website’s speed. Caching helps achieve a low TTFB score. TTFB (Time to First Byte) measures how long a browser has to wait before receiving the first byte of data from the server. The longer it takes to receive the data, the longer it takes to display the page.
  • Low Server Resource Utilization: If a server is utilizing low resources, it automatically processes the requests faster, thus helping in the site’s fast rendering. This makes your WordPress site faster.

Do you need a WordPress Caching Plugin?

Now that we have discussed caching and the types of caching that you can use to improve the speed of your webpage let’s discuss whether your site needs a WordPress Caching Plugin.

A WordPress Caching plugin helps you enable/disable, rebuild, and configure the caching options for your website.

You do need a caching plugin if your website is running on a shared server where resources are limited and you cannot optimize them to the fullest.

However, if you are on managed hosting where caching is done at the server level, then you do not usually require a caching plugin. Your hosting provider will take care of that for you. Since the caching is done at the server level, it is much faster than most caching plugins.

As we discussed above, our websites need some sort of caching, either at the server level or through caching plugins.
