6 Best Cache Plugins For WordPress to Speed up Your Blog

One of the things you can do to speed up slow slow-loading websites is to install one of the best cache plugins for WordPress on your site.

WordPress caching plugins help reduce the number of HTTPS requests. It enables compression, improves performance, defers off-screen images, and combines and inlines CSS and JavaScript files.

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

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

A WordPress cache plugin can do all these tasks and achieve a faster page speed 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 plugins 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 the exact cache in website performance.

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 requested information from your 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 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 on every subsequent visit.

This reduces the load on your web host servers, reduces page loading time significantly, 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 is the best cache plugin for WordPress blogs year after year.

Unlike many other WordPress caching plugins, WP Rocket is beginner-friendly. You don’t need 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 font, and cache-preloading.

When Gzip compression is enabled in WP Rocket, it compresses the HTML, CSS, and JavaScript files. It helps reduce total page size and makes your WordPress pages load faster.

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 optional optimization features you can turn on/off at will.

These include CSS and Javascript minification, lazy image load, delay 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.

As you will expect, WP Rocket is a premium-only cache plugin. No wonder it gives so much more than any other WordPress cache plugin.

6. WP Super Cache

2+ million active installations?

Yes!

WP Super cache is arguably one of the best free WordPress cache plugins. It is brought to you by the same people that give 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. All not logged-in users 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, it requires editing the h.access file.

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.

And like the expert mode, It requires a custom permalink, and a portion of your WordPress pages is served dynamically.

WP-cache caching cached 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 a bit slower than the expert and simple mode.

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.

Conclusion…

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’ function is not cached.

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.
