10 Best WordPress Cache Plugins for 2020

Today, the Internet is all about speed! In order to rank well on search engines, one of the few attributes of the website is that it should be fast. Nobody wants to use a website which is slow. It drives away potential customers and maybe some of the users would simply click the back button before even viewing it.

Before discovering the best WordPress cache plugins, one of the first things to know is the current situation of your website using a free service like Pingdom Tools. The website allows you to get information on the loading time of your pages and the improvements you can make. One of the improvements you will be recommended by Pingdom Tools is precisely to install a WordPress cache plugin.

What Is Caching?

To put it simply, when a user visits a page of your website, he loads all the elements. So there are a number of requests that are sent to the server. Each of them increases the loading time of the page. This is the principle of a dynamic website, every time the page is displayed by a new visitor, all elements are requested from the web server through queries.

This is useful if your content is changed at each visit, but in the case of articles or pages, this is not the case. This content is modified only when you make a change in the editor to update it. The rest of the time is always the same article. It is therefore useless to leave it in dynamics.

To give you an example of a query, the very content of your article (text, addresses of images, categories) will be loaded from your database. It will take several requests to do that. All of this is transparent to you and the visitor, but this has an impact on the server and the loading time of the page.

The larger your database (the more articles, comments, elements, etc.) it contains, the longer it takes to load requests. You can also limit the revisions of WordPress articles to preserve your database a little.

How a Cache Plugin Improves Website Speed?

We have just seen how a dynamic page works. When you install a cache plugin, it will turn your pages into static. This means that the first visitor to pass on your page will load all the elements as for a dynamic page.

The difference is that the elements loaded by this first visit will be loaded into an HTML page and saved as a copy on the server as a static file (in a cache folder). The second (and subsequent) visitor will no longer access the dynamic page, but the one that has been saved in the cache folder.

This will contain the elements that do not need to be reloaded each time the page is displayed. To resume the previous example, the text of your article will already be contained in the cached HTML file so no query will be used to retrieve it from the database. The example is for the text, but many other elements will be directly contained in the HTML file without needing to be generated again.

This will dramatically decrease the loading speed of your pages. The user experience will be improved and you will get better positioning in the search engines.

A WordPress cache plugin can make a large difference to your website. It is a process which creates static HTML pages of every other page on your website. It takes away the hassle of retrieving data from your database or executing a PHP code to display your page every time a visitor comes to visit your website.

Best WordPress Cache Plugins

Now everyone knows how important a fast website is. The quickest and most effective way to speed up your page with caching tools. However, there are many so I tested and compared 10 best WordPress cache plugins, i.e.:

Testing Environment for the Performance Test

To test the cache plugins, I have set up a one-page staging website on a managed WordPress hosting at Cloudways. I have tested the staging website with Pingdom Tools (location: New York, USA). Each plugin was tested multiple times with default settings and the best value was noted. Although these say nothing about the actual speed of the website, provide very good evidence for the optimization measures.

Test Result Without Cache Plugin

In the first step, I looked at the load time of staging website without any caching plugin installed:

It is definitely worth using a caching plugin! Most tools have similar features, but the free plugins are somehow more efficient than paid ones.

This is mainly due to the additional features such as the lazy load of images, delayed loading of scripts, font optimization and generation of critical CSS. Further advantages of the premium plugins are the support and the continuous development and improvement of the functions.

But is it really worth it to invest money? Yes and no. As the test shows, even the free plugins deliver very good speed values. I, therefore, recommend Breeze or Hummingbird Page Speed Optimization to the cost-conscious normal user. Both are absolutely easy to use, cost nothing and do a good job.

If you would like to have a super fast website and are willing to invest money, WP Rocket is the right choice for you. The plugin makes the page really fast and you do not have to spend too much time on the right settings. Therefore, it is also suitable for inexperienced users. And if there are problems, you can always contact the fast and helpful support. There is also an extensive documentation and help topics on the website.

Final Thoughts

It is quite difficult to single out any of the aforementioned plugins for caching. Besides, there are other cache plugins that are available for use on the WordPress plugins directory. However, there are only a few marginal benefits that separate each of the plugins.

So, my advice to you would be to find out what your requirements are and then test the plugins in this list to see which suits you the best. Test each of the features it offers to make an informed decision.
