Steps to Install and Use CDN to Increase Website Speed

Step 1: Analyze Your Website’s CDN Performance

To check if your website is taking advantage of the CDN, you can use website analytics tools such as GTmetrix. Besides, there are many other tools  such as Webpage Test, Pingdom Tools, Dotcom-Monitor, …

The test will give you the result. If your website has CDN installed, then try other ways to increase the speed of a website. If your website does not have CDN installed, please continue to follow to increase the speed of the website.

After accessing the website, enter the domain name of the website you want to check. The results of the website’s performance will appear on the screen.

Looking at the photos, you can see that the GretaThemes website takes full advantage of the effectiveness of CDN with static assets: 100/100. This is just to indicate that the files on your website are loaded via CDN or not. We will install the CDN for a website that does not have the support of CDN yet or with a low CDN score to raise the speed of the website if the grade is less than 80/100.

Step 2: Select an Appropriate CDN for Your Website

As mentioned above, there are two options at this step: you may choose to use a CDN free provided by Cloudflare or use a CDN which you have to pay for the speedup of the website.

If you are running a small website with moderate traffic, the free CDN version may be more than enough. However, if your traffic level is increasing and there is a sudden increase in the use of resources, a paid CDN would be a better option to raise the speed of the website.

Below, we will guide you to install the free CDN from Cloudflare because most websites use this free version and the operation is extremely simple and easy to understand.
