Best WordPress Cache Plugins

If you are on this page, I can feel your pain. You must be facing a speed issue with your WordPress website. From my experience, I can say that 90% of WordPress users face this issue at the beginning. But don’t worry. I had been there, and I also looked for solutions. Unfortunately, many of those solutions did not help me. Therefore, I compiled these 7 best WordPress Cache plugins from my personal experience. 

Caching is a major component of WordPress performance. A WordPress site’s caching system works by storing static content in the web server’s cache, so it doesn’t have to be generated every time a visitor loads the page. This article will help you select the best cache plugins for WordPress sites and improve your Website’s loading speeds.

I will cover both free and paid cache plugins in this article. If you own a small site, then a free cache plugin can be enough to speed up your WordPress website. But if you have a large site with a good number of visitors or are planning to earn from your site, I will highly recommend buying premium features. 

Let’s start with some basics. 

Caching is not the only reason that makes your website slow. There are many other reasons also. So you should know How to Speed Up Your WordPress Website

What is Website Caching? 

Caching is a technique used in website technology to store frequently accessed data in a temporary storage area so that it can be quickly accessed when needed. This speeds up the loading of pages and reduces the amount of bandwidth used.

Caching is a technique used in website technology to speed up the loading of pages. When a user visits a website, the web server looks for the requested page in its cache. If it finds the page, it serves the cached copy to the user. If the page is not in the cache, the server retrieves it from the database and creates a new cache entry.

If the previous definition was too techy for you, allow me to explain this in the following paragraph. 

Suppose a user is visiting a webpage of your Website. In that case, that user’s browser will make a request to your hosting server for various files (such as HTML, CSS, JavaScript, pictures, and more) when they visit a page on your site. Then, your server constructs these resources and returns them to the user’s browser, allowing the latter to display the web page.

Now think, if thousands of visitors visit the same page multiple times, the web server needs to use resources to show the same page over and over. That’s when caching comes to rescue your webserver. 

Some data from your web pages may be kept locally on the user’s device (Typically, inside the browser.) if your Website employs caching. Caching information makes it available much more quickly than searching for it on a remote server. When a user returns to a certain page on your site, their browser will retrieve some of the necessary data directly from their local storage rather than from your server.

What Exactly happens when you Activate a Caching plugin in WordPress?

When a webpage of your WordPress website loads, there is a behind-the-scenes procedure that involves loading a page. Information (queries) must be transmitted to and from the database to load the page. 

In other words, PHP language uses the query to retrieve data from your WordPress database and creates the HTML page that your visitors see. Given the number of steps involved, it takes some time for the site to load fully with accurate information. And if the web server needs to process all the queries from the users, it needs to use resources that can slow down your Website. 

A Caching plugin comes to rescue your web server from doing this repetitive task. 

Remember what we learned in the previous section? Caching helps speed up the Website’s loading the next time you visit it because your browser doesn’t have to download all of the files again. 

WordPress caching plugins work in a similar way by storing a cached version of your Website on the server. When a user visits your Website, they are served the cached version of the site, which is much faster than loading the entire page from scratch each time. 

WordPress caching plugins can also improve site performance during development or testing. By caching pages and posts, you can avoid having to load them each time you visit the site.

As a result, WordPress caching plugins can dramatically improve the speed of your Website. There are many different WordPress caching plugins available, so choosing one compatible with your theme and plugins is important. 

Types of Caching that a WordPress Caching Plugin Perform 

Before talking about the best WordPress cache plugin, I think you should know a little more about caching. It will help you to select the right plugin to solve all issues and improve the speed of your Website. 

There are two types of caching protocols 

  • Server-side Caching 
  • Client-side Caching

Client Side Caching 

Every Website has a finite amount of resources that can be used to render the pages and content. For example, if a website has 1000 pages and each page uses 100KB of bandwidth, then the Website would use 1GB of bandwidth to render all 1000 pages.

If a user visits the Website and only views the home page, then the Website does not have to use all 1000 pages to render the home page. The Website can instead cache the home page and use the resources to render the other pages when the user requests one.

This is called client-side caching. Client-side caching is a technique that can be used on websites to improve their performance of the Website.

Client-side caching is not a new technology. In fact, it is a common technique that is used to improve the performance of websites.

There are a few different types of client-side caching:

  • HTTP Cache
  • CSS Cache 
  • HTML Cache
  • JavaScript Cache

Server Side Caching 

Server-side caching is a technique that can be used to improve the performance of a website. Server-side caching allows the Website to store copies of pages that have been requested so that subsequent requests for those pages can be processed more quickly. 

Server-side caching can be used to improve the performance of the Website. Caching is useful when there is a large amount of traffic on a website, and the content for each page may change frequently. This can be helpful when the content of a page is frequently updated or when there are large amounts of website traffic.

Server-side caching includes 

  • Database query caching
  • Page caching
  • Opcode caching
  • Object-based caching

Why is the Speed of your WordPress website so Important? 


The first reason is that the speed of a website is one of the main factors people use to decide whether or not to visit it. If a website is slow to load, it can definitely affect how people feel about it. Research shows that if a website does not load in under 2 seconds, more than 50% of visitors don’t visit the Website. And if people don’t feel comfortable visiting a website, that could lead to lost sales and lost revenue. 

SEO Factor 

The speed of a website is also an important factor when it comes to search engine rankings. Speed is one of the factors that Google looks at when ranking a website. If a website is slow to load, it can affect how high it ranks on Google. And if a website ranks poorly in Google, that can lead to lost traffic and lost revenue.

User Satisfaction 

The speed of a website is also an important factor when it comes to customer satisfaction. If a website is slow to load, it can lead to frustrating experiences for customers. And if customers are frustrated with a website, that can lead to them leaving the Website and likely never coming back.
