For those of you who are asking what a CDN is , it's a Content Delivery Network. Basically it scoops up all your site content, distributes it across multiple servers across the globe and when someone goes to access your content they are delivered it from their closest server, majorly speeding up the load time. People love fast websites and Google loves fast websites . According to MaxCDN "users could be anywhere in the world yet your hosting is only hosted in one place, let’s say New York. Now if a visitor from England comes to your website they must load your website from New York. The distance the information must travel is very far and will make the website slow for this user. If you had a CDN, it would load your website from a local server, say one in England, so your website for this user would be very fast." In fact most websites see at least a 10 percent improvement in the SERPS after speeding up their site.
