10 Best WordPress Caching Plugins

Faster loading speed is a crucial factor for the success of any website. That is where the caching plugin plays its part. 

By using a caching plugin, your WordPress stores the static HTML version of your page. This decreases the server processing time and results in improved site performance and faster loading speed. 

Today, there are hundreds of caching plugins on the market. We have handpicked the 10 best WordPress caching plugins based on the market review and performance analysis. 

Each plugin may have more or fewer features than the other. We ran these plugins on a test site to make sure they are actually worth your time and consideration. So rest assured, each plugin will get the job done efficiently. 

But before going through the list, let’s introduce you to the concept of caching. 

What is Caching on WordPress?

Whenever anyone visits your website, their browser automatically downloads static content of your site, such as HTML, JavaScript, CSS, and images. Browsers store these files in local storage. Now, these files are known as caches. 

Now, when the same visitor revisits your website, the content loads much faster on their browser as their system already has a few contents of your website. Their browser has to make comparatively few requests to your servers. This improves the loading speed and the site’s overall performance. So, caching is an efficient and effective way to boost your website’s performance and speed

How Does Caching Work?

Whenever you receive a visitor on your site, here is what happens: 

  1. Their browser sends a request to your server to display the content.
  2. The server then gathers the necessary data as requested. 
  3. The server then sends these data to the visitor’s browser as an HTML file.
  4. Their browser receives those data, processes them, converts them, and displays them as a wholesome web page. 

When the same user revisits your website, the browser needs to repeat the same process. It is time-consuming and also uses more resources on your server. 

Using a caching plugin provides an easy way to load your site. A cache stores the HTML file on the visitor’s browser so that it can skip the first three steps when revisiting your website. 

Why Do You Need a Caching Plugin?

As per Kissmetrics, 40% of the site visitors leave your site if your website takes more than 3 seconds to load. Plus, it will also reduce the conversion rate by 7%. 

Another study shows a 53% bounce rate in the visitor’s number if a site takes more than 7 seconds to load. Well, 53% is a huge number. 

So, how do you improve your site’s performance?

There are many ways to improve your site’s performance– sign up for a better hosting plan, change your hosting provider, opt for a performance-optimized theme or use caching plugins. 

Among all, using the caching plugin is one of the easiest and effective ways to improve the site’s performance. Look at some major benefits of caching in WordPress: 

1. Faster Loading Speed. 

We have been highlighting this since the beginning of the article. However, it is essential to mention it here, as well as it is the primary benefit of caching.

If you have a startup hosting plan, using a caching plugin is the best way to reduce your server load. It reduces I/O operations and saves your server’s memory. This will ensure that you can enjoy a learner hosting package that delivers a larger server’s performance.

When To Clear WordPress Cache?

Caching is an efficient way to improve your site’s performance and provide a better user experience. But sometimes, the cache files block you from previewing the changes on the frontend right away. This is when you need to clear the cache. 

Some of the reason to clear changes are:

1. Design Changes

You may need to change your site’s design time and again. You may need to add or update the contact information, add/remove products, change their details, change the theme layout, and such. 

However, you may not see the changes on your page right after making those changes. It happens mainly because the caching mechanism has not detected any change on your site. Thus, it keeps on loading your previous website version. Clearing the cache will resolve this issue. 

2. New Content

Google notes those websites that update their content and add new ones frequently. Contents may be blog posts, case studies, or anything relevant to the website. 

But when your server retains the old cache files, your web page does not show the new content. So, it creates a problem ranking on search engines. Here, you may need to clear the cache.

3. Theme or Plugin Update

Whenever you update your theme or a plugin, it is better to clear the cache. Doing so will ensure your web page loads all the files, codes, and appearance on the HTTPS request. 

4. Database Changes

Any changes you make on your database or even migrating the database requires clearing of the cache. Doing so prevents the error message display on the browser.
