Best WordPress caching plugins to speed up your website

What Is a Cache?

A cache is a collection of temporarily stored data for quick access upon request. In computers, information is usually stored on a hard disk. When it is requested, a computer needs to run several processes before the information can be presented.

Caching solves this issue by processing the frequently requested information and then storing it in temporary storage or memory. This allows computers to access the file quickly.

The same caching concept can also be used by WordPress websites to improve performance and make your website load faster.

You see, WordPress is a dynamic content management system. This means that each time a user visits your website, WordPress fetches information from the database and then runs several other steps before the web page is sent to the user’s browser. For details, see our article on how WordPress actually works.

This makes your website load slower when a lot of users are visiting it at the same time.

Caching allows your WordPress site to skip a lot of steps. Instead of going through the whole page generation process every time, your caching plugin makes a copy of the page after the first load and then serves that cached version to every subsequent user.

How caching works?

Why Is Caching Important?

Caching is important because it reduces the load on your WordPress hosting servers and makes your website run faster. You need a proper caching setup to improve your WordPress speed and performance.

A faster website improves user experience and encourages users to visit more pages. This also helps you boost engagement and the time users spend on your website.

A faster website helps you drive even more traffic to your website from organic search. Google gives a significant SEO advantage to faster websites which helps you rank higher in search results.

That being said, let’s take a look at the best WordPress caching plugins that you can use to boost your website speed.

1. WP Rocket


WP Rocket is the best WordPress caching plugin in the market. It is the easiest and most beginner-friendly caching plugin, which is a big help if you don’t know the technical terms used for different caching options.

It allows users to instantly cache their website with one click. Its crawler automatically fetches your WordPress pages to build up the cache.

The plugin then automatically turns on the recommended WordPress caching settings like gzip compression, page cache, and cache pre-loading.

WP Rocket also includes optional features that you can turn on to further improve performance. This includes lazy loading images, CDN support, DNS pre-fetching, minification, and more.

This is why we use WP Rocket on WPBeginner to speed up our site.

2. WP Super Cache

WP Super Cache

WP Super Cache is another popular WordPress caching plugin. It is free and comes highly recommended by many of the top WordPress hosting companies.

WP Super Cache plugin includes all recommended caching features that you will need to speed up your website. This includes gzip compression, page cache, cache pre-loading, CDN support, and advanced cache preload.

It includes a comprehensive settings section with a separate tab for easy setup. For detailed instructions, see our article on how to install and set up the WP Super Cache plugin.

3. W3 Total Cache

W3 Total Cache

W3 Total Cache is one of the most popular WordPress caching plugins. It is a comprehensive WordPress caching plugin with a ton of options which may make it appear a bit intimidating for beginners.

It includes all the features you will need to properly set up a WordPress cache. This includes page cache, object cache, gzip compression, limited minification support, and CDN support.

Beginners may find W3 Total Cache a bit difficult to use. For detailed setup instructions, see our article on how to install and set up the W3 Total Cache plugin.

4. Sucuri Firewall


Sucuri is the best WordPress firewall and security plugin. As a website firewall, Sucuri comes with a built-in option to cache your website content and enable gzip compression with a click of a button.

It is the best option for any website because Sucuri is a DNS-level firewall. This means that they can serve cached content to your users even before their request reaches your website. This gives your website an incredible performance boost.

5. Built-in Cache Plugins from Hosting

Caching helps significantly reduce the load on hosting servers allowing them to perform optimally. This is why many managed WordPress hosting companies now offer their own built-in caching solutions.

If your website is hosted with one of the following hosting companies, then you can use their built-in caching plugins for your websites.

SG SuperCacher

SiteGround offers a built-in caching solution with all their hosting plans. It can be enabled from your hosting account’s dashboard.

SiteGround Super Cacher

Once enabled, their dynamic WordPress caching will improve your website speed anywhere from 50-500%. They have also added an option for site owners to enable Memcache.

SiteGround has also added Brotli compression which can also help you unlock 15-20% speed improvements.

Overall SiteGround’s caching has improved a ton. If you’re on their platform, you really wouldn’t need any caching plugins like WP Rocket or others.

WP Engine Caching

WP Engine is one of the best managed WordPress hosting companies. Their hosting plans come with built-in caching and performance optimization.

You can manage settings and clear the cache from your WordPress admin dashboard. Simply click on the WP Engine menu and under the General settings tab you can manage WP Engine cache settings.

  1. It looks like WP Rocket is no longer a free plugin. It is no longer listed in the plugin library. Or I just can’t find it.

    • WP Rocket is a paid plugin that is not on the repository at the moment.


    • We would only recommend using one caching plugin at a time but if it is from your hosting’s end and not a plugin then you may want to try adding a caching plugin.


  2. Hi – Thank you for the information.

    I read somewhere that some cache plug ins don’t work with certain themes, is there anyway of checking if WP rocket will be ok with my theme or am I worrying over nothing?

    • Normally that shouldn’t be an issue but if you reach out to your theme’s support they should be able to let you know of any conflicts.


    • Yes they are different, depending on the plugins you use they also can work with each other.


  3. The BlueHost Portal is different now. I selected Asset & Web Pages option, as that was what was recommended. It gives me the option at the bottom to clear my cache (everything or just specific URLs). Should I do this? Little worried, since it can’t be undone! I use SMUSH plugin to compress my photos. My site seems to load quickly. What are links I can test the speed or is that on my dashboard? Newbie learning new things every day. :)

  4. I am with Bluehost so guess I could use their caching but there is another plugin that sounds worthwhile called WP Optimize, which is supposed to be great for caching but also compresses images and optimises your database. But I’m wondering if this (or any other cache plugin) would conflict with the caching functionality in Bluehost? (Although there is an article on Bluehost’s website that recommends using WP Super Cache, which suggests it wouldn’t conflict, but this also makes me wonder if they don’t think their own caching is sufficient?).

    • You would want to check with BlueHost for the specifics in case that is an old article but normally you should only have one caching plugin active at a time


      • Thanks, yeh I remember reading that somewhere. So does Bluehost’s caching ability count as a plugin? i.e. if I turn on caching in Bluehost does that mean I shouldn’t install a separate caching plugin?

        • If you find a plugin from BlueHost on your site then it’s a WordPress plugin, otherwise, it would be a second level of caching

  5. Keep up the great work! I am using wp rocket on my site and it help me a lot. Thanks for the efforts you put it in this article.

  6. I am using wp super cache and it seems to be a wonderful plugin for me to speed up my site.

  7. WP Rocket user for a couple of years now and going strong. Be it a WordPress + WooCommerce or just a WordPress site, it’s going great and strong.

    Plus they update it often, and fix any problems sometimes before i encounter them :-))

    On a side note, WP Engine cache is pretty neat too :)

    • If you using some managed host like WP Engine so do not install the cache plugins it will conflict. Do not use like Super Cache or WP Rocket.

      You can disable some junks stuff use Speed Demon plugin and only using the cache from their hosting servers (Nginx FastCGI)
