Content Delivery Networks

Home » Webmaster Resources » Content Delivery Networks

Content delivery networks, sometimes abbreviated to CDN’s, are services that have a distribution of servers across the world. They store cached copies of your website across all of their worldwide data centres to greatly reduce the response times from your website. This also reduces the bandwidth used in your hosting plan.

By utilising a Content delivery network, you can considerably reduce the time it takes for your web pages to load. This will improve the user experience of your visitors. Search engines such as Google also factor the speed of a website into their ranking algorithms, therefore you should receive more traffic from search engines if your page loading time is reduced.

Content delivery networks can also stop your website from going down when you experience a traffic spike. While many hosting plans cannot cope with a sudden rush of traffic, CDN’s are designed to cope with the level of traffic that the front page of Reddit can bring.
