What is a cache used for in WordPress?

Ideally, webmasters are not only concerned with the content of the pages, but they are also in charge of a good user experience (UX). If your users can navigate the web page easily, they stay longer on it and interact more, which, on the other hand, is positive for positioning in Google . However, for a good user experience, not only is a striking and intelligible design essential, but a short loading time is also necessary ..

When a user visits your web page , a great variety of processes necessary for the correct display of the page are automatically started in the background . Some of them are loading and executing JavaScript, reading the CSS file or querying the database. All these processes happen in the background and require loading time, during which the user must wait, until the web page is displayed correctly. If it takes too long, it has a negative effect on both the user experience and the ranking of the page in Google. However, there is a solution that shortens this load time : caching.

advice

Caching is an important option, but not the only one, to speed up WordPress. Other practical options are to take care of the code, the different plugins or the database. Also the size of images and videos greatly affects the loading speed..

As usual, WordPress offers a wide variety of cache plugins . However, the basic function is the same in all of them: the plugin saves static copies of each page and shows them to visitors in a matter of seconds.

Why clear the WordPress cache?

Although a cache plugin shortens the loading time of your web page, buffering a version of the page also has drawbacks . After an update, the cache usually shows an old version of the web page ; changes in the backend or in the CSS file are not immediately visible to the visitor. For this reason, it is important to clear the WordPress cache after having made all the changes and updates:

  • After updating the WordPress system , it is important to clear the cache so that all the updated items are displayed.
advice

Generally, you only need to clear the cache in WordPress if the updates affect the display of the website . However, it is usually easier to clear the cache after each update than to check if the system requires it after a specific update.

  • Also after updating the plugins , it is advisable to clear the WordPress cache so that all the changes made are visible in the interface.
  • The same applies to changes to applications or widgets , which are often only visible to website visitors, once the WordPress cache has been cleared.

If you plan to make significant updates or changes to the website, it is recommended to create a WordPress backup so that, in case of problems, it is possible to recover the original version.

advice

With professional WordPress hosting , you improve the response time of your website by up to 50% and, in this way, also the user experience and your positioning in Google.
