How to use Cloudflare CDN

Cloudflare CDN is a powerful tool for improving website performance by caching content on servers around the world. In this guide, we’ll walk you through the process of setting up and using Cloudflare CDN on your website.

Step 1: Sign up for a Cloudflare account

To use Cloudflare CDN, you’ll first need to sign up for a Cloudflare account. This process is free and can be completed in just a few minutes. Simply go to and click the “Sign Up” button in the top right corner of the page.

Next, you’ll be asked to enter your email address and choose a password. Once you’ve done this, click the “Create Account” button.

You’ll then be prompted to add your website to Cloudflare. Enter your website’s URL and click the “Add Site” button.

Cloudflare will then scan your website for DNS records and present you with a list of records to confirm. Make sure all of the records are correct and then click the “Continue” button.

Step 2: Configure DNS settings

Once Cloudflare has scanned your website for DNS records, you’ll need to configure your DNS settings to point to Cloudflare. Cloudflare will provide you with two nameservers that you’ll need to update your DNS settings with.

To do this, go to your domain registrar’s website (where you purchased your domain) and find the DNS settings for your domain. Replace the existing nameservers with the ones provided by Cloudflare.

Once you’ve updated your DNS settings, it may take a few minutes for the changes to propagate. You can check the status of your DNS configuration on the Cloudflare dashboard.

Step 3: Enable CDN

To enable CDN on your website, go to the “Speed” tab on the Cloudflare dashboard and click the “Optimization” button.

Next, toggle the “Auto Minify” and “Rocket Loader” settings to “On”. These settings will help to optimize your website’s code and improve performance.

Then, scroll down to the “Caching” section and toggle the “Cache Level” setting to “Standard”. This will enable Cloudflare’s CDN to cache static content on your website.

Finally, click the “Save and Deploy” button to save your changes.

Step 4: Test your website

Once you’ve enabled CDN on your website, it’s important to test your website to make sure everything is working properly.

One way to do this is to use a tool like GTmetrix or Pingdom to test your website’s performance before and after enabling CDN. These tools will show you how much faster your website is loading and which specific elements of your website are benefiting from CDN caching.

You can also use the “Performance” tab on the Cloudflare dashboard to monitor your website’s performance and identify any issues.

Step 5: Configure advanced settings

Cloudflare offers a range of advanced settings that can help to further optimize your website’s performance and security. Here are a few examples:

  • Firewall rules: You can create custom firewall rules to block malicious traffic and protect your website from attacks.
  • SSL/TLS settings: Cloudflare offers a range of SSL/TLS settings, including free and paid certificates, to help secure your website’s traffic.
  • Page rules: You can create custom page rules to control how Cloudflare handles specific pages or content on your website.

To access these advanced settings, go to the “Firewall”, “SSL/TLS”, or “Page Rules” tabs on the Cloudflare dashboard.


Cloudflare CDN is a powerful tool for improving website performance and security. By following the steps outlined in this guide, you can enable CDN on your website and start enjoying faster load times and better user experiences.

Remember to regularly monitor your website’s performance and adjust your settings as needed to ensure optimal performance.
