12 Best CDNs for WordPress in 2021

If your WordPress site is site is slow and you want to speed it up, a CDN might be just what you need. Content Delivery Networks can be very effective in boosting your website’s performance and in turn, your user experience. In this article, we will give you a list of the best CDN providers as options for you to help in speeding up your website. But first, let’s explain what a CDN does and why it is important.

What is a Content Delivery Network (CDN)?

A Content Delivery Network is a network of servers located in different parts of the world, that keeps cached static content from websites and delivers them based on the geographic location of the user.

How does a CDN work?

CDNs cache and store static content like images, CSS files, JavaScript files, Flash, and the likes on the multiple servers spread around in different locations. The CDNs then deliver the copies to your site visitors from the server located close to the geographical location of your visitor. The goal is to minimize the distance between your site’s visitors and your website’s origin server.

Your CDN provider’s job is only to keep the static resources of your website and not to host your original website files. You still need a web hosting account to build your website and keep your website files.

Here’s a simple illustration of the use of CDN. You have hosted your site on a particular web hosting platform, their server is in New York City. Now, you have people visiting your site from all over the world. When a person in Paris visits your site, your website files will be fetched from the server in New York to deliver to them.

This can affect the speed and loading time of your site, due to the number of requests from all over the world, being made to the same single server. It can even crash the server when traffic peaks, making your site temporarily unavailable. A CDN keeps a static copy of your website files in different locations around the world. So, your visitors will be seeing the cached copy of your website from the nearest CDN server rather than loading the original files all the way from your web host’s server. This will reduce the load on your hosting server and make your visitors experience fast speed when visiting your website.

So, the CDN will bring up your website pages through its local server in Paris or somewhere near France.

You need a CDN to improve your user experience, boost your ranking, improve your website performance and increase website security. Here are the best WordPress CDN providers in the world and some of them even offer their services for free:
