Your website may have dozens of hits each month. Higher numbers in the hundreds, thousands, or millions may appear. Given that your website likely serves the same or similar content on a regular basis. Wouldn’t it be nice if the server could remember these files and serve the website each time? Huh?

Short explanation of Caching

This means that every web page you visit on your website requires a request to your server, processing by that server including database queries, and the final result being sent from the server to the user’s browser. The result is a complete website with all the files and elements that make up the look and feel of your website. For example, you have headers, images, menus and a blog. The server has to process all these requests. So it takes time before the entire web page is delivered to the user.

That’s where selecting a WordPress caching plugin comes in. The cache plugin tells the server to save some files to disk or RAM, depending on your configuration. Therefore, you can memorise and re-produce the same content that you have provided in the past. This greatly increases the speed at which web pages are loaded directly from cache. Essentially, caching reduces the amount of work required to generate page-views.

When Do You Need a WordPress Caching Plugin?

Above I talked a small amount about speed. But are WordPress caching plugins always necessary? And what are the benefits with caching?. So, if you manage a server or even use shared hosting. A caching plugin will makes perfect sense.

The disadvantage of WordPress caching plugins

However, sometimes you don’t need a caching plugin at all. If you choose a managed WordPress host like FastComet, they have out of the box WordPress Optimisation for you. Caching is done at the server level and is much faster in most cases.

But, you do need some type of Caching

Whether you have a server-level cache or use plugins. You will always need some form of caching. So what are some other benefits of caching?

  • Make your website faster for your users.
  • It’s improves overall user experience. Users are more likely to look around because the site moves faster for them. Faster websites are known to lower bounce rates because people don’t care about waiting 10 seconds for a page to load.
  • The server uses fewer resources. This is related to speed, as less resources means a faster site. Also, it reduces the load on your web server. Which is very important when it comes to highly dynamic websites.
  • Search engine optimisation could improve – Once again, this relates to speed and the user experience. But all these improvements these areas will give search engines the ability to to index your site higher.
  • See a lower TTFB (Time To First Byte) – Caching is one of the easiest ways to lower your TTFB.

Find The Best WordPress Caching Plugins

If you manage your own server or use shared hosting, try these caching plugins. As some of them are more intuitive than others. They all have great reviews. Many caching plugins posts compare the speed of caching plugins and try to sell you which one is the best.

However, this is nearly impossible as these plugins behave differently depending on their own servers, configurations, resources and even physical location. I love it so much, but it’s also unfair to plugin authors to consider plugins to be “fastest”.

Not to mention that there are hundreds of different settings that can be enabled or disabled. Therefore, you should always test your WordPress cache plugins yourself.
