We live in a world of instant gratification, so if your webpage doesn’t load quickly, you’ve probably already lost a visitor. No matter if your visitors are checking out your site via mobile or desktop, you’ve got to provide them with an enjoyable user experience. 

If you’re looking for ways to speed up your WordPress site, you may have come across the idea of caching. Caching is a great way to minimize the processes of loading a website and get content out to your users, and there are some best WordPress caching plugins that we want you to know about. 

According to Google, website viewers whose sites or apps remember their past behavior are favored by 58%. This is made possible due to caching. Not only that, if your load time goes from 1 second to 3 seconds, the bounce probability increases 32%. This is a big implication and it shows that only a few simple seconds can make or break your website performance and overall traffic. 

Caching can help you to avoid this, and you should absolutely be doing it. In this guide, we’re going to help you understand what cache is and introduce you to five of the best WordPress caching plugins to optimize your site! Let’s do it.  

What is Cache?

best WordPress caching plugins how does caching work

Cache (pronounced “cash”) is data that is temporarily stored so that it can be easily and quickly accessed when requested. The most common way that computers store information is via hard disk; if that information is requested, the computer must then run a number of processes before that information can be presented to the user. 

Caching is the solution to this problem— cache processes information that is frequently requested and stores it in a temporary memory storage. Computers can then access the information quickly without having to go through all of the same processes. 

This same idea of caching on computers can be applied to WordPress websites; caching will improve your website’s performance and make your website load times faster. The best WordPress caching plugins make this possible.

WordPress is a Content Management System (CMS), and every time a user visits your website, WordPress has to get the information from the database and then run multiple processes before the website gets sent to the visitor’s browser. 

This process can make your website load times lag, especially when many users are visiting your site simultaneously. 

When you use caching, your WordPress can bypass many of these steps and get your content there quicker. Your caching plugin makes a copy of the page after the first load and will serve that cached version to all subsequent visitors, effectively skipping the entire website page generation process. Your WordPress site will be able to do this when you install the best WordPress caching plugins.

Why is Caching Important

As you may have deduced from above, caching is vital for your WordPress site because it minimizes the load on your WordPress hosting servers and allows your WordPress site to run faster. You’ll want to take advantage of the best WordPress caching plugins if you seek an optimized WordPress performance. 

When your website and its pages load faster, the user experience is greatly improved and your visitors will be more likely to browse other pages. This boosts your engagement and increases the amount of time users spend on your WordPress site. 

If your website loads slowly, they may not be motivated to visit any other pages, and they may leave altogether, which hurts your bounce rate. 

In addition, a fast-loading website will get you better SEO results. Google favors websites that load quickly, giving them an SEO advantage and higher search result rankings. This means you can drive more traffic to your website through organic search. 

So, it’s clear that WP caching plugins can help your WordPress site performance. Let’s examine 5 of the best WordPress Caching Plugins and some of their standout features. 

1. WP Rocket

For beginners and those with less technical knowledge, WP Rocket is an easy-to-use caching plugin, eliminating confusion for those who aren’t as savvy with the jargon related to caching options. 

WP Rocket offers users the capability to cache their website instantly in just one click. It uses a crawler to access your WordPress pages and build up the cache, after which the plugin automatically turns on the recommended WordPress caching settings including gzip compression, page cache, and cache pre-loading. 

This is what makes it among the best WordPress caching plugins for beginners— you won’t be required to dive into the settings yourself. It really does everything pretty much on its own. 

WP Rocket includes additional features that you can apply to improve your performance ever further, such as lazy image loading, CDN support, DNS prefetching, minification, and more. 

It’s used by almost 2 million websites, making it a top contender for the best WordPress caching plugins.

Sucuri Firewall comes in at number four on our list of best WordPress caching plugins. It is widely recognized as the best WordPress firewall and security plugin, so in addition to that, you will gain multiple caching opinions and website speed optimization with Sucuri.

It’s powerful among WP caching plugins because it’s a DNS-level firewall, meaning that it can serve cached content to your website visitors even before the request hits your website. This does wonders for your website performance and can get you up to 70% website speed improvement. 

5. Built-in Cache Plugins from Hosting

If you aren’t using caching for your WordPress site, your hosting server will have a heavier load placed on them, which could ultimately affect all sites that are being hosted on that server. This could cause a big problem for hosting providers, which is why many managed WordPress hosting companies offer proprietary, built-in WP caching plugins. 

Many different WordPress hosting providers provide their clients with caching solutions, so it’s something to keep in mind when choosing a host for your WordPress site. The following list isn’t comprehensive, but here we’ll take a look into three of the top WordPress hosting providers and how they eliminate the need for one of the aforementioned best WordPress caching plugins. 

Bluehost Caching Features

Bluehost is one of the premier WordPress web hosting sites on the market today. They help you get started fast, offer total design freedom, provide a free domain name for your first year, as well as 24/7 support.

WP Engine is widely known as the most effective and comprehensive managed WordPress hosting solution, so it’s no surprise that it comes with its own version of the best WordPress caching plugins already built in. 

EverCache is the name of WP Engine’s proprietary front-end system that helps to make all website visits fast and completely scalable. This caching system helps to ensure that your site speed is always up to par, no matter how many visitors your website is getting.

  • Clear Object Cache

Just as with Bluehost, you can also manage your caching via the WordPress admin page on the general settings tab. There’s an option that reads Purge All Caches which will get rid of all the above listed caches. 

Ultimately WP Engine offers one of the best WordPress caching plugins in-house, so you won’t have to go looking for any external plugins. They won’t let you use them even if you would prefer to, however.

The three best WordPress caching plugins that are banned by WP Engine are WP Super Cache, WP File Cache, and W3 Total Cache. 

Kinsta Caching Features

The final WordPress hosting service we examined in terms of the best WordPress caching plugins is Kinsta, another one of the top solutions in the industry. Kinsta helps take care of all of your needs and is quite comparable to WP Engine, although depending on who you ask, they’ll have a favorite.

Kinsta is a platform that hosts your WordPress offering ultimate speed, free migrations, security by Cloudflare, and daily backups to keep your WordPress site secure no matter what.
