I know the same as many new developer-facing these types of problems and looking for free or paid services. Many Paid service providers are available for CDN services, and yes, they are outstanding in performance, like MAXCDN, Cloudfront, etc. However, you can check Cloudflare if your budget is low and you want free CDN service. Cloudflare is a perfect choice for a newbie. But today, I will show you something different about CDN, and It will help you create your content delivery network in your server and improve your website speed within a few seconds.

Setup Free CDN to Improve Site Speed with W3 Total Cache Plugin

Set up free CDN and Improve site speed in WordPress with the help of the W3 total cache plugin. So First, Install W3 Total Cache Plugin and Follow the steps below to create your CDN.

Install W3 Total Cache Plugin -> General Setting, then Change CDN to Enable and CDN Type to Generic Mirror. Now you can go to CDN Option located in the Performance Tab and make changes, same as the below screenshot. Now we have almost done CDN Setting in W3 Total Cache. But before this final step, we do some settings in cpanel also. Could you open your hosting account or Cpanel and create a new sub-domain? You can assign any name per your requirement, like, etc.

After creating the new sub-domain, make some changes in DNS records. I am using IPage hosting for Techgiks to point this new sub-domain host to my main domain. Click on DNS Tab and point your sub-domain to the central part. But sometimes, there is some manual work in IPage, like moving a file from the main domain to the sub-domain, which is time-consuming but works fine. See the below Image. But If you are using another type of Cpanels like Hostgator and Inmotion Hosting, then Make some changes in the Advance DNS Setting section.

Open Advanced DNS Zone Editor and Select your primary domain. A list of all domains and sub-domain will appear. First, select your newly created sub-domain with or without “WWW“. Next, click on edit and change CNAME to “”. That’s it. You have made a sub-domain; the sub-domain points to the main domain.  Go to your WordPress admin panel again, open CDN settings in the performance tab, and Click Modify attachment URLs.

A popup will appear and show you the number of posts. Click start, and Now all your Images, CSS, and JS are serving from your new self-hosted CDN. Self-Hosted CDN is free and will improve site speed. Before CDN Techgiks, the loading time was 12 seconds, but it will reduce to 3 seconds after this setup. But make sure your sub-domain should be a cookie-free domain.
