What is Caching in WordPress?

To answer simply, caching refers to a process of improving performance by creating static versions of your content and serving that to your visitors. Instead of rendering or fetching a page that requires back and forth queries to be sent to and from the database, your visitors will be served with the static pages which generally render much more quickly thus contributing to faster performance of your website. 

Caching is best used for posts or pages that do not require much change to them or ones that you won’t be updating daily. By serving static pages to your visitors and avoiding the back and forth queries to and from the database will lead to less load on the server, hence better performance. There are several different types of caching solutions available for WordPress. 

The most popular method is using a WordPress caching plugin like WP Rocket or WP Super Cache. For more recommendations, please refer to our article on the best WordPress clear cache plugins. The plugin approach is one of the simplest and the easiest ones, especially for beginners and novices of WordPress. 

These plugins will offer some capable and advanced caching properties to control what files and media are cached when the cache expires when the cache is cleaned up, and more. Besides plugins, you can clear cache in WordPress using the built-in capability that some of the hosting providers offer. If you are using a web application to maintain your website’s security, some of the providers will also include a cache to speed your website and reduce uptime. Also, some modern web browsers will also store cached versions of pages on your web browser.

Why should you clear cache in WordPress?

The reason we use website caching is that it provides an optimal experience for visitors. By serving your visitors a static version of your content your website will load much more quickly and will revitalize your site at a greater rate. 

When undergoing major changes on your website, once it’s all finished you might notice that these changes do not manifest on your website, making it impossible for you or your visitors to see the newer version and the updates on your website. You will be presented with an older version of your website, and it’s not the result you would expect. 

Learning to clear cache in WordPress will help you that the most recent version is live on your website for everyone to see and explore. Clearing your cache can often help with troubleshooting too, depending on what you’re trying to fix. In a nutshell, clearing your cache simply means clearing the temporary storage of your site. Learning how to clear your cache in WordPress will make for a seamless experience while managing and maintaining your website.
