How to Clear Your Cache in WordPress

If you are looking to increase user experience and boost SEO on your website, the first thing you need to make sure of is that your website is working at its full speed. If your website has optimized speed, you can expect lower bounce rates and higher engagement and conversations. This will also ensure that Google ranks your website higher on the search result page. One of the most important components that ensure your website is working quickly is caching. It’s basically storing copies of your site data to ensure quicker page loading in future requests. However, as cached files can expire, it’s very important to regularly clear your cache in WordPress.

What is WordPress cache and how does it work?

As we already mentioned, the cache is a temporary storage location for static content. It helps websites run faster and thus increases user experience. Each time you visit a website, your browser sends requests to the specific site’s server. As it can take a couple of minutes for the server to fetch and show the content, caching was created to make things faster.

Your website speed is crucial for improving the user experience and generating more traffic.

What web caching does is download the website’s static content and stores it as cache files. As your browser will already have cached content, it won’t have to create too many requests to the website’s server.

When it comes to web caching, it’s important to know that there are two main systems:

  1. Client-side caching (or clearing your browser cache) stores the static content in local storage. Whenever a user revisits a specific website, the content will load faster. This happens because there is a cached version already stored in the browser’s cache folder.
  2. Server-side caching has pretty much the same concept as browser caching. The difference is that this type of caching uses a server to store the cached data of a certain website. This is a great solution for high-traffic websites given that server cache can store site data from multiple databases.

Why should you clear your cache in WordPress?

You might think that clearing your cache doesn’t make sense given that it increases your site performance and helps sites with limited resources use less bandwidth. However, you have to keep in mind that whenever you change and tweak your WordPress website, the content might not update on the front-end. This happens if your WordPress server continues displaying the cached version of your pages.

The solution is simple – clear your cache in WordPress. After doing this, the caching system will automatically store the updated version of your website. This way, you’ll make sure your visitors always see the latest version of your website pages. Out of many reasons to clear your cache in WordPress, this might be the most important one.
