Best CDN Providers for WordPress in 2021

For this article, we have decided to compile a list of the best CDN providers for your website. But what’s a CDN you might ask? CDN stands for Content Delivery Network and refers to a geographical network of proxy servers whose goal is to deliver content as quickly as possible.

Using a CDN provider will help you improve the performance of your website, and that is why you should be focusing on finding the right and the best CDN to incorporate on your WordPress website. This is where this article will be able to assist you as we have collected the best CDN providers and narrowed them down to only the most professional providers. But what are the best CDN providers?

Check out who made our list. But before we get into the collection of what are the best CDN providers, we will shortly explain what a CDN is and how does CDN works. Let’s get going. 

How does a CDN work?

To put this simply, a CDN is a network of services and data centers in a lot of different geographical locations, what this does is connect the visitor of your website with the nearest network, thus minimizing the distance your visitors and your website’s origin server and having your website load faster. 

When using shared hosting, all your files and shared in a certain geographical data center, let’s say USA, and if the user is far from that location, it can take a lot of time for the site to load. Thus having the best CDN on your website will reduce the loading time, and improve your site’s performance. Keep in mind that your website’s speed and performance is an important SEO ranking factor, that is why is often advised that you, as a website owner find the best CDN provider for the occasion. 

So how does a CDN works? Usually these content delivery networks caches static pages of your website and stores them on multiple servers in various locations, and when users request to load a page on your website, a CDN will redirect the request to the nearest server. 

This reduces the loading time and makes your website faster, and this way providing a better user-experience. Now that we have got the basics covered, let’s take a look on the best CDN providers to help you make the right choice for your website.
