Last updated - February 24, 2020

Speed is one of the primary aspects of user experience on the web. Your website needs to be super fast to keep the users interested in what you are offering on your site. There are several strategies you can try out to optimize the speed and performance of your site, if it is built on WordPress. Using a Content Delivery Network (CDN) is one of the common strategies to increase page load speed. In this article, we will discuss some of the top free CDN services you can use to improve site performance.

What is CDN?

A Content Delivery Network is a series of network servers that are located in different geographical locations spread across the world. They serve static resources on your web page based on the geographical location of the user.

A WordPress page is dynamically loaded based on what a user clicks on your website. However, a dynamic WordPress page will have some static components on it such as javascript, images, etc. A content delivery network helps in storing and serving copies of these static resources, to reduce the load of the hosting server when a user makes a request on your site.

Generally, your hosting server will be located in a single location. When there is a surge in traffic, serving all user requests from a single location can affect page loading speeds. As the content delivery network is spread across different locations, it can selectively serve static files from a server located closer to the user.

Free CDN Services

There are several free CDN services that you can make use of if you are concerned of any additional expenses in maintaining your WordPress site.
