WordPress caching can be complicated if you do not know what you are doing. Trying to explain caching for different complex technologies might take a full chapter. However, you can think of caching as a simple math problem.

What’s five times 2? Anyone can immediately tell you the answer is 10. Why is that? Because at some point in life, one had to memorize the answer. This same thing happens to your WordPress website when you install a caching plugin. Your site “memorizes” some stuff to access those resources faster. This is how caching works on a website.

Caching (pronounced “cashing”) is the process of storing data in a cache. A cache is a temporary storage area.

– Wikipedia

Your website may be visited thousands of times each month. Maybe you attract hundreds, thousands, or millions of traffic each month. If you observe, you can find out that most of the time your website is serving the same or similar content on a daily basis.

Wouldn’t it be great if the server could remember those files to serve up your site every time? That’s what the best WordPress caching plugins do for your site.

Why Do You Need a WordPress Caching Plugin?

Whether you have server-level caching like Litespeed or Varnish, plugin-level caching with plugins like WP Super Cache or Cache Enabler, you’ll need caching in your website. You might ask what the benefits of caching are.

  • Caching Improves Your Overall User Experience: Since the website load faster for users, they are now more likely to browse around. Faster sites are preferred by Google and rank higher in search engines. Also, speedier loading websites are known for decreasing bounce rates as people become frustrated if a page loads for 10 seconds.
  • Fewer Resource Usage Means Faster Loading Time: When your website uses fewer resources, it becomes much faster. Lesser resource usage means a lower strain on your server. This is important when it comes to highly dynamic websites.
  • You May See a Boost in Search Engine Optimization: As we mentioned earlier, since March, Google is giving higher ranks to those websites which load faster. A fast site + an excellent User Experience always means SEO improvement.
  • WordPress Caching Helps to Load Balance: When you are serving a large amount of traffic daily, you must need a caching plugin to handle those traffic. If your website hits the main web server other than the cache, then your fixed resources will soon run out. Cache helps to serve your content to more concurrent users.

3. WP Super Cache

WP Super Cache lets you generate static HTML files from a dynamic website. Static files take less time to serve to users. Serving static HTML is a faster alternative to processing WordPress PHP scripts, which can be costly as well as time-consuming.

The expert mode uses mod_rewrite to serve your static files and help to ensure that your site performs well under extreme load from heavy traffic. This is helpful if you are having a lot more traffic and serving hundreds of concurrent users.

The ‘Simple’ method uses PHP to server your cached files, hence isn’t quite as fast. However, if your server does not have Apache’s mod_rewrite module, then you can use this mode.

Since WP Super Cache is lightweight, simple to use, and easy to configure, it’s a good fit for all who do not want to tinker with configurations. WP Super Cache can also sync with your files with a Content Delivery Network (CDN), which can further boost your site’s speed.

Thank you for including LiteSpeed Cache on your list of best caching plugins!

I noticed that LiteSpeed isn’t included in any of the comparison graphs at the end of the post. Is that because you don’t have a LiteSpeed server to test it on? If so, I just wanted to let you know that there’s a new free license available that could be useful to you in future comparisons.

Also, you mentioned whether the other plugins were free or premium, but you didn’t do the same for LiteSpeed. For the record, the LiteSpeed Cache plugin is 100% free.

Thank you so much, Lisa for your valuable feedback. Yes, you were right. I did not have any LiteSpeed Web Server where I could test your plugins. However, thanks for your link. Soon I will add the comparison of Litespeed in the comparison graphs. Sorry, for the pricing mistake. I promptly updated the info and mentioned that Litespeed Cache is completely free.

I use wp super cache & wp total cache on some of my sites. But wp rocket seems to be the best in terms of speed. It requires less optimization when compared to the other plugins mentioned

I have activated the LiteSpeed cache plugin that run on my website. Currently just purchased WP Rocket plugin, wondering can i use together with LiteSpeed cache plugin? If so, what should i take note of, so as not being interfere with each other?

Thanks!

NO. Don’t do that. The two plugin will conflict with each other. If your server is Litespeed based, then go with Litespeed Cache. Litespeed cache performs like a beast in litespeed server. However, if you are not using Litespeed server, then go with WP Rocket.

Now I’m creating a site and choosing a plugin for caching. Your article helped me a lot and answered many questions. Thank you!
