Using a CDN can help you to make your website fast. In this article, we will talk about how you can add a CDN to your WordPress site and increase its performance. So, gear up & commence the voyage.

What is a CDN?

A CDN is the abbreviation of Content Delivery Network. Actually, it’s a combination of multiple servers scattered in different geographical locations of the World. When visitors try to access your website, the CDN diverts their requests to the nearest servers. It allows them to visit your website quickly and take the desired action easily (such as downloading website materials, signing up for a newsletters, sale, etc,).

Let’s understand it with an example- Suppose your website is hosted in the UK. If a visitor tries to access it from Australia, it will take some time to display the result for the requested term in case you don’t use a CDN. If you use a CDN, it transfers the user’s request to the local server (Australian) of the website and helps him/her to browse your site easily.

Main advantages of using a CDN

  • It diminishes the total number of HTTP requests to the main server of your website.
  • Improves the overall experience of visitors when they browse your site.
  • Make your website super fast and helps it to float up in the SERP of Google, allowing you to get lots of organic traffic.
  • Helps you to save your valuable resources and cuts the website operation & maintenance cost up to a certain extent.
  • Can handle a tremendous increase in website traffic.

To do so, sign into your CDN account, navigate to the control panel, set up a pull zone and give a name to it. In case you want to use a custom domain, then you will have to create CNAME record. As soon as you accomplish this step, you should check the setup and save the changes you have made.

7. Use FTP to upload files

Many times, website admins choose a CDN which doesn’t support WordPress plugins. Don’t get frustrated if you face the same scenario. Most of the CDNs support file uploading through FTP. So, when you choose this option, you need to collect some useful credentials(such as the FTP settings offered by your CDN service provider, security protocol, FTP host, login details, etc,) as soon as possible and keep them in ready mode to use.

8. Manual Uploading

If you don’t want to use plugins to add a CDN to your site, then you can do it manually. But, you should use this method only when you are a hardcore WordPress user and are familiar with complex technical terms and procedures. Don’t try this method if you are a new WordPress user.


  • First of all, you need to upload all important files (uploads folders, static content, etc,) to the CDN you choose.
  • Now configure WordPress and search those files in the CDN.
  • Configure your Cpanel and add a CNAME record to your DNS.
