Free CDN for WordPress websites to decrease your load time and SEO

WordPress is an extensive CMS with limitless customization, with brilliant themes and plugins. And to engage with visitors, most of us use a lot of media contents such as images and videos. A free CDN for WordPress will come handy in such cases.

However, we often do not realize that with more and more contents and customizations, our website gets slower.

A Slow Website Is A Red Flag

Nowadays, a slow website is a big concern and should be dealt with properly. It is best practice to keep website loading speed below 3 secs.

(You can check your website loading speed using Pingdom.)

You should know that the Google algorithm detects slow sites and hence, your SEO rankings will be affected if you do not prioritize speeding up your site.

A slow site will lower visitors’ UX (User Experience) and will probably increase your bounce rate, i.e. more people might leave your site even before it may load properly.

Hence, one of the most important things to do when optimizing your WordPress site is to speed up the website loading speed as much as possible.

Now, there are several ways to speed up a WordPress site. However, one of the best ways is to use CDN.

What Is CDN?

Content Delivery Network, or as we call it, CDN, is a network of distributed servers. Any static data and resources of your website such as images, videos, CSS files, JavaScript files, etc. may be stored here. And when a person tries to visit your site, the CDN will deliver these data and resources through servers that are closest to that visitor’s location.

The main reason why you should consider using a CDN is that it will make sure the static resources on your site will load faster and will ensure lower HTTP requests.

This will definitely make your website faster, and reduce bounce rate; a big plus for SEO and UX.

Another reason is that you usually get a single server from your hosting provider. Too many visitors at a time will increase HTTP requests which may lead to a slower website, or even trigger a server crash (when there is a huge amount of traffic, all at once).

Now that you know the importance of using a CDN, let us look at 10 free CDN for WordPress sites that you can choose from to help you speed up your WordPress site.
