HostArmada Top Choice WordPress Caching Plugins for 2020

7 minutes reading

We at HostArmada understand the importance of website speed and optimization for every site owner. Therefore, we have invested our efforts to develop a fast, secure, and stable server environment so we can grant exceptional website performance to all our customers. While the server-side is unquestionably a significant factor for website loading speed, there are other essential elements as well.

Typically to speed up a site, you need to review its code and content and optimize those areas to enhance its performance. Unfortunately, not every user can write or fine-tune code, thus, an alternative solution was brought to light – caching plugins.

This convenient method of speeding up WordPress sites allows everyone to enjoy a fast loading website without going through the hassle of hiring a developer or investing time in learning to code.

Caching technology is quite complicated and we will not go over all the technical details surrounding it. We will attempt to give you an idea of how it works, and we will include the benefits of implementing it on your WordPress-based website.

What is caching?

The caching tech revolves around storing data types of your website (commonly static files such as HTML, CSS, and JS) in a storage called “cache”, which you can imagine as a memory for intermediate data. When this technology is active, your website’s first visit will fill this storage with the respective data types. Each consequent request towards the already-cached page will not query the server directly for the resources needed to deliver it to the client’s browser. Instead, the data will be pulled from this temporary storage and returned to the viewer’s browser faster, ultimately resulting in a much quicker loading speed.

How does Caching affect WordPress site performance?

In addition to speeding up your website, there are other benefits of using caching plugins:

  • Improves UX (User Experience) as they navigate more smoothly on your pages.
  • Reduces the number of requests made to your server, thus making it more stable and able to handle more traffic.
  • Lowers TTFB (Time To First Byte), which is quite an important metric, especially if you are aiming to increase your SEO and your ranking in Search Engines (Google, Bing, Yahoo, etc.)

In the next few paragraphs, we will be going over a few WordPress caching plugins that we believe can be a great addition to your site’s arsenal. We have installed and used each of the plugins from this list to give our readers an accurate idea of what they can expect from implementing them on their sites.

Which caching plugins should you consider for your WordPress website?

We have made a series of blog posts, each reviewing a specific WordPress caching plugin. Each post gives detailed know-how of the plugin and its settings, and you should check out the one that seems most appealing to you. To satisfy each type of WordPress user’s needs, we have included both premium and free solutions and more complex and easy to use plugins.


LiteSpeed Cache

LiteSpeed Cache is a popular plugin amongst the community and for a good reason. A solid choice, especially if your server environment is empowered by LiteSpeed webserver. Be sure to check our comprehensive tutorial series on the plugin.

  • Requires a LiteSpeed-powered server to be used, otherwise, the majority of the functionalities will not work.
