How to Set Up WP Fastest Cache (Beginner’s Guide)

Do you want to set up WP Fastest Cache plugin on your website? Configuring the plugin correctly will help you improve the website’s speed. We have got you covered if you are looking for a step-by-step guide to configuring WP Fastest Cache. This article will show you how to complete the task without any hassle.

But before we move forward, let’s see why and when we need to use a WordPress caching plugin.

Why and When Do You Need a Caching Plugin?

Using a caching plugin on your website will greatly help you optimize the overall performance. By default, when someone lands on one of your blog posts, the web server will fetch contents from the MySQL database every time. When you have a few visitors, there won’t be any issues with the performance.

But when you start getting more website visitors, calling MySQL database content every time could cause performance issues. As you know, a website’s speed and performance are crucial in ranking and user experience.

This is where caching plugins come in.

The plugins will create a cached copy of your website. And when someone requests a page or post, the plugin will serve the content from the cached copy. This way, you can reduce the requests to the MySQL database. Hence, you can improve the speed and performance of the website.

Personal blogs, business websites, and eCommerce stores can use caching plugins.

Now you know what caching plugins are and why you need them. The next section will explain what to look for in a caching plugin.

What to Look for In a Caching Plugin?

When you are looking for a WordPress caching plugin, check out these options:

  • Ease of use: A caching plugin with a simple configuration method would be a good fit. It helps users to tweak the plugin without any hassle.
  • Optimization methods: This is the main thing you should check. The optimization methods help you speed up the website. So, visit the features page of the caching plugin to understand more about the optimization methods available.
  • Integrations: Connecting the caching plugin with a CDN provider, Analytics, could help you optimize your website further. Hence, checking the integration options available in the plugin is mandatory.
  • Updates: The selected plugin needs to get updates from the developer with the latest optimization methods. So, how often the plugin gets updated needs to be considered.
  • Compatibility: if you run an online store with plugins like WooCommerce, or Easy Digital Downloads, you must ensure the selected caching plugin is compatible with your WordPress configuration.

Now you know how to choose the best caching plugin for your website. Next, let’s look at a quick introduction to WP Fastest Cache.

After entering the URLs, you can complete the CDN integration.

If you have connected your CDN with the website, let’s move to the next section, where you can clean your website’s database directly through WP Fastest Cache.

6) Database Optimization

Having a bulky MySQL database is not feasible. Since the website completely relies on the database for information, we need to ensure that the database is clean and well-optimized.

With WP Fastest Cache’s database optimization tools, you can clean the DB. This is a premium feature and not available in the free version plugin.

With the DB optimization feature, you can

  • Remove trashed content
  • Clean post revisions
  • Get rid of trackbacks
  • Eliminate pingbacks
  • Clear transients

When you handle a multi-author blog, the database must be optimized well. When authors work on multiple posts, they will save a decent amount of revisions in the database. Hence, database optimization is no more optional.

That’s it!

This is how you can set up WP Fastest Cache on your WordPress website. You can always tweak the options to match it with your liking.

Here, we will show you how to use GTmetrix to test the website’s speed.

First, go to GTmetrix. There, you need to enter the website’s domain name and click on Test your Site.
