10 Best CDN Services for WordPress 2021 (Boost Site Speed)

Are you looking for the best CDN services for WordPress? Then, you have come to the right place.

A CDN (Content Delivery Network), as the name suggests, is a network of servers that are dedicated to caching and delivering the static content of your website for faster website loading. Static content may include HTML files, images, videos, etc.

In this article, we’ll tell you about the best WordPress CDN services that make your website lightning fast. Also, we’ll talk briefly about how a CDN helps speed up your website.

A. How does a CDN Make Your Website Faster?

The CDN services cache the content of your website on their servers. These contents are delivered from a server that is geographically closest to the user that is trying to access your website. Since the user gets the content from the closest server, the content delivery speed is much faster. 

Not to be misunderstood with website hosting services, a CDN doesn’t host your website. It only stores the static content of your website so that it can be delivered to a user at faster speeds.

B. Why Do you Need a WordPress CDN Service?

Normally, the contents of your website are delivered from the servers of your web hosting service. But as your website starts to gain more and more traffic, the performance or speed of your website will slowly decrease, especially if you’re on a shared hosting service.

And if your website traffic is too much for the hosting server, it might even crash. To prevent all this, you need one of the best CDN services for WordPress in the market.

When using a CDN service, you’ll reap the following benefits:

  • The loading speed of your site will be much faster.
  • The servers of CDN services will take some load off of your hosting server.
  • A faster website feels more interactive and will increase viewer engagement.
  • Your website will see better traffic, better feedback, and improved SEO rankings.
  • Some of the best CDN services for WordPress will provide you with free SSL certificates.
  • The CDN services will also provide security features like DDoS (Distributed Denial of Service) mitigation,

Obviously, that’s not all. You’ll get tons of other features as well. For now, lets have a look at some of the best CDN services for WordPress.
