Edge SEO and SEO testing on the edge

SEO at the edge means any SEO changes that are made after the HTML is created by your CMS or origin server before it is served to the user. These changes are made closer to the user by modifying the HTML on the way “through” a CDN-like layer. The biggest benefit is that you aren’t constrained in the changes you can make. Between engineering resource constraints, and technical limitations of some web platforms, there are certain kinds of changes that can be difficult, prohibitively expensive, or even impossible to make via a CMS or origin code change. Many of these changes are quick and easy to make by modifying the HTML output at the edge.
