What is Cache?

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

When you visit a website, you use an app or device for the first time, and 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 Matter 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 information they need from your WordPress website database.

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

This is where a caching plugin comes in handy to help skip a lot of the process and make WordPress pages load extremely fast.

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 on every subsequent visit.

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

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

With that said, let’s explore some of the best cache plugins for WordPress blogs in 2023.

1. WP Rocket

WP Rocket website homepage - WordPress plugin

WP Rocket is the best cache plugin for WordPress blogs year after year. Also, it is one of the best cache plugins for woo-commerce websites.

Over 3.7 million WordPress blogs optimized page speed by WP Rocket; this is a number no other WordPress caching plugin comes close to.

Unlike many other caching plugins for WordPress, WP Rocket is beginner-friendly. You don’t need to be tech-savvy to configure the settings for maximum optimization of page speed.

Upon activation, WP Rocket automatically deploys the best WordPress caching settings like Gzip compression, browser cache, page cache, cross-origin supports for web fonts and cache-preloading.

WP Rocket also auto-disables WordPress emojis, optimizes Google font files, auto-detect, and supports third-party WordPress plugins.

While WP Rocket’s main feature is cache, it also includes file, codes, and image optimization features you can turn on/off at will.

These include CSS and Javascript minification, image lazy load, delayed JavaScript execution, CSS delivery optimization, and load JavaScript deferred.

You can A/B test WP Rocket to see how much of a difference it brings to your site speed.

You can do this by appending a query parameter (?nowprocket) to the end of an individual URL on your site. This will render the page without any cache optimization features, just a simple WordPress page.

Before running this experiment on your blog, run a website speed test with tools like GTmetrix, Pingdom, Google PageSpeed Insight, etc.

This will help you to know if there is any significant improvement in loading speed and website performance after deploying WP Rocket on your website.

WP Rocket is a paid cache plugin for WordPress. No wonder it gives so much more than any other best WordPress cache plugin.

For a single website license with one year of support and updates, WP Rocket costs $59/yr. And for three website licenses with one-year updates and support, you’ll buy for $119/yr.

3. W3 Total Cache

You still have to configure each cache and performance feature manually. If you can’t do it yourself, the W3 Total cache support team will do it for you.

It costs $99/yr for the W3 total cache pro license key.

You’ll have to purchase a separate license key for each website if you need to use the W3 total cache on multiple websites. In a WordPress multi-site, you can use a single website license on all websites.

6. WP Super Cache

WP Super cache - WordPress plugin

2+ million active installations?


WP Super cache is arguably one of the best free WordPress cache plugins. It is brought to you by the same people who gave you WordPress- Automattic.

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

When a user requests the server, your web server will generate static HTML files instead of WordPress processing PHP database requests.

This significantly speeds up page load time, reduces latency, and serves cached pages thousands of times to your site’s visitors.

By default, users without leaving comments on your blog do not have to view password-protected pages. Users who are not logged in will be served the static-generated HTML pages.

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

The plugin works in 3 ways to serve users the cached file or pages and by speed:

  • Expert
  • Simple
  • WP-cache caching

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

This is the fastest and completely bypasses the PHP database call. However, editing the h.access file is required.

You could break your site altogether if you don’t know what you’re doing here. The Simple mode is the recommended way to use the plugin. It doesn’t modify the h.access file.

Like the expert mode, it requires a custom permalink, and a portion of your WordPress pages is served dynamically.

WP-Cache caches pages for logged-in users, registered comments authors, or URLs with parameters.

If super caching is disabled in the WP Super cache, WP-cache also caches pages for unknown users. It is the most flexible cache option but is a bit slower than the expert and simple modes.

WP super cache is an utterly 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 support most CDN services.


While several caching plugins exist in the WordPress directory, your website needs only one.

I intend to help you simplify the search process for the best WordPress cache plugins.

Although there are still a handful of good cache plugins for WordPress blogs like Autotomize, many of these plugins’ functions do not cache.

Many of these plugins focus on file minification, image optimization, etc.

The 6 WordPress caching plugins listed here are suitable for every WordPress blog. I’ll advise you to go for WP Rocket if you want my recommendation.

WP Rocket offers more for page speed improvement and performance as a premium WordPress plugin than any other cache plugin in the market.

  2. Shamsudeen,

    1. Hi, Jenna,

      Glad to read WP Rocket made the difference in improving page speed and boost performance for your site. Thanks for reading through, Jenna.

  3. Hi Shamsudeen!

    I’ve been familiar with these plugins for a while now, but I always like reading over articles like these to see if anything’s changed, or if I can learn something new. This time I did!

    When I picked a caching plugin several years ago, WP Rocket was around and recommended by just about everyone, however it scored lower in speed tests than WP Fastest Cache (which is what I ended up going with.) WP Rocket still might have been the most recommended, but it was pretty universally agreed in marketing circles that this was only because of their generous affiliate program and not because it was actually the best plugin out there.

    Out of curiosity I looked for updated data after reading this post and independent tests are now placing WP Rocket above the others in speed test comparisons. I’m glad to see that they’ve continued investing in it and it actually may be the best caching plugin now!

    1. Hey, James,

      Good to have you around here once again and many thanks for providing an unbias “short” review of WP Rocket and WP Fastest Cache.

      Yes, a few years ago when WP Rocket was launched, it wasn’t the best cache plugin out there for speed and performance. Over the years, the WP Media team had done greats works improving the WP Rocket plugin for speed and performance. I think that has paid off well.

      Now I see many big outlets, mainstream media houses, blogs, and many top digital marketers using and recommending WP Rocket above other cache plugins.

      These are not affiliates, and of course, not in the position to receive incentives for endorsing a product.

      Thanks, James, glad you find this helpful.
