13 Best CDN Services for WordPress 2021 (To Boost Speed)

Last Updated: 19 mins By: ThemeGrill Author

Want to know which is the best CDN service for WordPress to boost your site performance? Wondering where to look?

That’s okay because this article has a curated collection of awesome CDN services for WordPress to start with.

Slow loading pages make us promptly close the tab. As a result, the bad user experience affects traffic, revenue, lead generation, and SEO. Companies are scrambling to avoid this by putting up websites that load under seconds or even less than a second.

To make this possible, you’ll need a good CDN service to work alongside your hosting service.

What is CDN? How Do CDNs Work?

Basically, a Content Delivery Network (CDN) has servers in multiple locations spread around the globe. These servers store a cached copy of website data like HTML, images, and videos that reside in the main server at a single location.

And when an internet user views your website, the data request is directed to the server closest to the user instead of the main server. This decreases the speed with which it retrieves data and presents it to the viewer resulting in a pleasant user experience.

That’s why CDN services are invaluable for companies with global users. So, let’s learn more about these services, shall we?

Reasons to Use CDN Service for WordPress

It’s a no-brainer that CDN boosts a website’s speed. But, you may be wondering what other reasons there are to use a CDN service for WordPress. Well, to list a few:

  • Most CDN services also offer security features such as Distributed Denial of Service (DDoS) protection and Secure Sockets Layer (SSL) certificate.
  • Since the server requests are spread across multiple servers, the load on the main server decreases. This, in turn, lessens the chances of the main server crashing.
  • When the requests going to the server decreases, so does the bandwidth consumption. Hence, a sudden surge of traffic won’t rack up a hefty price.
  • You don’t have to worry about a server crashing because there’s always another one waiting in line for a request.
  • A fast WordPress site helps you rank better in Google search results.
