Frequently Asked QuestionsWhy would I want to use a CDN?
A CDN allows static content (mostly images) to be delivered faster to your site visitors by serving them from edge servers geographically closer to their location. This means faster load times and possibly improved SEO.
How do I deploy a CDN on my site?
My site uses CloudFlare but this tool says I don't use a CDN. Why?
CloudFlare is not really a CDN in the traditional sense. CloudFlare is essentially a distributed reverse proxy. A true CDN does not require you to route all of your traffic through them as CloudFlare does. You can still deploy a CDN in conjunction with CloudFlare though.
Why does this tools says I use a CDN but I'm certain I don't?
This is a false positive result based on the way this tool checks for a CDN. Most likely it found references to static resources on a sub-domain of the domain you tested and that sub-domain resides on a different IP address.
