Page loading speed has become important for webmasters especially since Google started using it as a ranking factor. People use different techniques to ensure their interfaces are served quickly to interested users. One such method used by website owners to speed up their entities is caching.
It involves storing a static version of the website on the server that is then provided to users in their browsers. WordPress website owners can use multiple options to enable the feature on their interfaces.
However, there can be some situations when they need to clear WordPress cache. In this article, we are discussing the methods that different types of users can employ to clear their cache.
What is Caching?
As mentioned before, caching involves storing the static copies of a page on your browser or server. The files that are chosen for static saving are usually those that do not undergo regular modifications.
Instead of loading the entire page whenever it is requested, the server now presents the saved copy in lesser time. This speeds up the rendering of a page in the browser leading to a satisfying user experience.
However, there are certain situations when you need to clear the cache. This requirement can arise when modifications are made to the interface’s content or design.
Let’s say you are a WordPress web designer who writes a post on his blog about the best themes this year. After some time, you find out that one product has been discontinued by its maker.
Now, if the cache is not cleared, the audience will continue to see the old version of the content. Flushing your cache also becomes necessary after a theme or plugin update so that all the new changes are visible to visitors.
