What is a CDN and How Can It Speed Up Your Website?

If you read our post on website speed, you’re aware of just how important loading speed is for user experience and ultimately the conversion rates on your website.

One concept you may not be aware of is the Content Delivery Network (CDN). A CDN can help your website load faster without you even knowing anything is going on behind the scenes.

What is a CDN?

As you know, when you’re using a hosting service, your website actually lives on a server somewhere and the data needs to move from that server to the visitor’s computer anytime someone tries to load your page.

A CDN is a network of servers in different geographic locations that all store certain information from your website. When a user from a particular location visits your site, the information is loaded from the closest server to them, helping to shave off valuable time from the loading speed.

Files that are typically hosted on a CDN are image files, stylesheets, JavaScript, video and audio files, web fonts, and file types like HTML, PDF, and ZIP. Another way to think about it is that CDN holds all the files that would typically live in your WordPress wp-content and wp-include folders.

When a visitor comes to your site, the core HTML is loaded from the original server, but all the resource-intensive files like CSS, javascript, and the rest of the above are loaded from a server that is closer geographically and optimized for this purpose. Loading the content from multiple servers also allows multiple parts of your website to be loaded at the same, ultimately speeding up the load time of your site.

In addition to helping your site load faster, a CDN can also help your SEO, because search engines have a preference for sites that load more quickly.

Bandwidth and Traffic Management

The diversification that you get from content delivery networks can help more than just your website’s load speed. Because your content lives on multiple servers, it can be delivered much more efficiently to all your users. For one, a CDN keeps the overall level of bandwidth low, because your usage is distributed among multiple servers. This also means that if your website experiences a surge of traffic, the multitude of users will likely be geographically distributed and will make use of different servers as well.
