Do you want to enhance the performance of your WordPress website?
Caching makes your site load quickly. So by enabling caching on your WordPress site, you can offer a better browsing experience to your visitors.
However, it’s important that you occasionally clear your cache to ensure your site functions as smoothly as possible.
In this guide, we’ll show you exactly how to clear your cache in WordPress. But before that, let’s look at how caching works and why you should clear your cache from time to time.
What Is Caching and Why Is It Important
Caching is the process of storing data in a temporary storage area called cache. It creates and saves a static version of frequently requested information so that it can serve future requests faster.
When you’re looking for a piece of information in WordPress, rendering and fetching the information requires queries to be sent to the database. Then the responses need to be sent back.
This increases your server load.
But by enabling caching, you can skip these steps because it will create and present a static copy of the requested information. This reduces the server load and really enhances your page’s loading speed.
Why Clear Your WordPress Site Cache
Sometimes the cache fails to detect any new changes that have taken place on a website because it’s still using the downloaded static content to load the results.
So instead of loading the new version, it continues to load the old version. This might prevent users from seeing the latest changes and the updated version of your site.
Clearing your cache can stop this from happening. Apart from that, it has several other benefits as well. Here are some of the reasons why WordPress caching is important.
- It optimizes your website for speed and performance.
- It reduces the load on your hosting server, which saves server memory and I/O operations. This can be a great advantage for users with limited hosting plans.
- It enhances loading speeds, which is an important ranking factor in Google. Since caching increases your loading speeds, your site will potentially rank higher with Google (provided you have good content and follow other SEO parameters).
Now let’s look step-by-step at how to clear your cache in WordPress.
Step 1: Clearing Your Browser Cache
The first step to clearing your WordPress cache is to clear your browser cache. Today, we’ll be using Google Chrome as our browser. Simply click on the Menu icon. Here you’ll see an option called More Tools » Clear Browsing Data. Click on this option.
You’ll see a popup appear on your screen. Here you can select the content you want to remove or delete from your browsing history. Don’t forget to select the cached images and files option. When you’re done, click on the Clear browsing data button.
That’s it. Your browser data will now be cleared. The time needed to clear your browsing history may vary depending on the amount of stored data.
Step 2: Clearing Cache With Your Web Host
Let’s now look at how to clear your cache in some of the popular managed WordPress hosting options.
WP Engine is one of the most popular managed WordPress hosting service providers. If you host your website with WP Engine, you don’t have to install a caching plugin separately because they run their own caching solution.
You can clear your WP Engine cache right from your WordPress admin area. For that, you need to click on the WP Engine menu item in the admin bar and then under the General settings option click on the Purge all caches button.
Your cache will now automatically be cleared out.
