Also, a good cache plugin will leverage browser and page caching, enable support for content delivery network, etc.

A one-second delay in website loading time can lead to loss of revenues, audience, low search engine ranking, and a high bounce rate.

You definitely don’t want any of the above metrics to happen to your online business.

According to Think with Google, a mobile site speed testing tool, you need to improve on your website pages to load in under 2.5 seconds.

Increasing page speed by 0.1-second can lead to a massive 8% increase in conversion and engagements.

The BIG problem is how do you increase WordPress page speed?

While there are many things, you can do to fix a slow-loading page, having a good cache function will significantly improve page speed.

Therefore, you need a cache system developed from the ground up to improve page speed, cached, and serve static files, boost performance and improve overall user experience.

A WordPress cache plugin can do all these tasks without touching a line of code or needing to be a developer.

So, in this article, I will share a list of the best cache plugin for WordPress to speed up your blog pages.

You will also improve the user experience, boost website performance, increase duel time, get more search engine visibility, and drive more revenue.

But before that, let’s define what exactly cache is in website performance.

What is Cache and why does it really matter to website performance?

A cache is a temporary special data storage space for storing static files that makes website contents, apps, devices, or browsers loads content faster and more efficiently.

When you visit a website, you use an app or device the first time, the cache system stores a copy of the content to your web browser, app, or device.

The next time you visit the website or use the app and request the same content URL, the cached page/content is served instead of a live version of the Url.

This process makes retrieving and downloading the content faster and improves the user experience.

Why Does Cache Matters to WordPress Websites?

The same concept of caching described above is also used in WordPress websites to improve page speed and optimize performance.

By default, WordPress is a dynamic content management system that runs many steps to serve users the requested information from your website database.

The process WordPress runs to serve users your website content makes loading of web pages slower, especially when many users are requesting information simultaneously.

This is where a caching plugin comes in handy to help skip a lot of the process and makes WordPress pages load insanely faster.

Instead of WordPress going through all the serving processes for every web page request, the caching plugin copies the web page after the first visit; it then serves the cached copy to every subsequent visit.

This reduces the load on your web host servers, reduces page loading time significantly, and improves user experience.

Since Google announced that page speed is part of its search algorithm signals, improving page loading time has become an integral SEO task.

On top of that, faster web pages mean more search engine traffic, leads, low bounce rate, and consequently more revenue generation.

With that being said, let’s explore some of the best cache plugins for WordPress blogs in 2021.

#5. WP Super Cache

2+ million active installations?

Yes!

WP Super cache is arguably one of the best free WordPress cache plugins. Brough to you by the same people that give you WordPress- Automattic.

Like any other WordPress cache plugin, WP super cache generates static HTML files of your dynamic WordPress pages. 

When a web page request is made, your web server will serve the user the generated static HTML files instead of WordPress processing PHP database requests.

This speeds up your WordPress page load time significantly and reduces latency. The cached pages can be served thousands of times to your site’s visitors.

By default, users who have not left comments on your blog. Site users who have not to view password-protected pages. And all not logged-in users will be served the static generated HTML pages.

WP Super cache is not beginners friendly. It requires a few tech skills to configure the plugins to work with your site.

The plugin work in 3 ways to serve users the cached file or pages and they’re ranked by speed:

The expert mode uses the Apache mod_rewrite. Or a similar module your web server uses to serve the “super cached” static file HTML files.

This is the fastest and completely bypasses the PHP database call. However, it requires editing the .htaccess file.

If you don’t know what you’re doing here, it’s easy to break your site completely. The Simple mode is the recommended way to use the plugin. It doesn’t require modifying the .htaccess file.

And it’s as fast as the expert mode. It requires a custom permalink, and a portion of your WordPress pages is served dynamically.

WP-cache caching is used to cache pages for logged-in users, registered comments authors, or URLs with parameters.

If “super caching” is disabled in the WP Super cache, WP-cache caching will also cached pages for unknown users. It is the most flexible cache option, a bit slower than the expert and simple mode.

WP super cache is a completely free-to-use plugin. But this does not take away its quality as a dependable free WordPress cache plugin.

The plugin integrates the OSSDL CDN off-linker to provide basic support for most CDN services.

Summary…

While over 1,000 caching plugins are in the WordPress plugin directory, your website needs only one caching plugin.

My intention here is to help you simplify the search process for the best WordPress cache plugins. And to bring you only the best caching plugin for a WordPress blog.

Although there are still a handful of good cache plugins for WordPress blogs out there like Autotomize, many of these plugins’ primary function is not cache function.
