Best CDN for WordPress Free

Are you searching for a free CDN for WordPress? Do you want to increase your site’s loading speed? If the answer is yes, then you’re at the right place. 

CDN stands for Content Delivery Network. It helps to boost your WordPress website’s performance by loading your content faster on your visitor’s side. It adds extra servers for your site and provides the content to users from a server nearest to them. Hence, the site loads faster.

CDNs are greatly useful but, they’re mostly paid services. Another way, some quality web hosting services include it in their package. But if you’re on a tight budget, then getting a CDN looks like a burden.  

But don’t worry. Luckily, there are some CDN services available free for WordPress sites. And, we’ve listed out the best of those free WordPress CDN services here. Let’s check them out! 

What is a CDN & Why Do You Need it on WordPress?

A CDN (Content Delivery Network) is a geographically distributed network of multiple servers spread across the world. Those servers on different locations work together to provide faster delivery of content.

Content Delivery Network (CDN)

CDN caches all your website’s static content (images, javascript files, and stylesheets) and stores them on its servers. Whenever a request comes, CDN provides it from the nearest server of the user’s location.

Overall it aims to load the website as quickly as possible. It reduces the distance by distributing the content from the nearest server. So, when the data gets delivered from the nearest location, it’s automatically going to take less time to load.

It not only makes your site faster but also gives you numerous benefits apart from that. Some more benefits of CDN are: 

  • Increases Website Ranking: Were you aware of the fact that search engines love fast-loading sites? Yes, and equally as much as your visitors do. So, with a CDN, your site might get better SEO rankings than before.
  • Improved Website Security: Plus, CDN is effective in protecting from DDoS (distributed denial-of-service) attacks. Using a CDN can minimize the constantly increasing security threats to some extent and make your site more secure

With that, you’ve got a fair bit of idea regarding CDN and its usefulness. Now, let’s check out the best free CDNs for WordPress sites.
