If you own or run a website, you probably know that loading time is an important factor for online success. But what is this “cache” that everyone is talking about? and why is it so important for your WordPress website?

What is a cache?

Simply put, cache is a memory that caches certain parts of your website to make them accessible more quickly.

Imagine your website is like a book and the cache is a bookmarking feature that allows you to jump directly to the interesting pages without having to start from the beginning each time. This means your website loads faster and your visitors don't have to wait for each page to reload.

But be careful: not all cache plugins are the same. Choosing the right plugin can make a huge difference. A good cache plugin can not only make your website faster, but also reduce the load on your servers and thus improve overall performance. In this article, we will look at the best WordPress cache plugins that will help you get your website running at top speed.

My own experience – I currently use WP Rocket and FlyingPress

I'll be honest: I had the best experience with WP Rocket, WP Fastest Cache and Flyingpress. What impresses me most about Flyingpress is its speed.

Litespeed Cache, on the other hand, I found to be too extensive and actually slowed down my website. Therefore, I cannot recommend Litespeed Cache.

Plugins I haven't tested: W3 Total Cache, WP Super Cache. I have researched the information above and am relying on their own information. I can't share any experience with these plugins because I haven't done any.

Frequently asked questions

We currently use FlyingPress for the lk-media website and WP Rocket for other sites.

We get along well with both plugins.

I think it depends on the website. In general, you should set each plugin individually. I have the best experience in terms of speed with Flyingpress.

A cache plugin is an essential tool for any WordPress website for several reasons:

  1. Speeding up loading time: A cache plugin caches static versions of your website content so they can load faster. This significantly reduces the loading time of your website, which not only improves the user experience but can also positively influence the ranking in search engines such as Google.
  2. Improve server performance: By reducing requests to the server, a cache plugin can significantly reduce server load. This allows your server to handle a larger number of visitors without affecting performance.
  3. Efficient use of resources: By delivering already generated pages, a cache plugin reduces the need for server resources such as CPU and memory. This allows your hosting provider to free up resources for other processes, thereby increasing the efficiency of your website.
  4. Better SEO ranking: The loading time of a website is an important factor for SEO ranking. Since cache plugins shorten loading time, this can have a positive effect on your website's ranking in search engines.
