Edge SEO: Optimizing at the CDN Level for Speed & Rank | Marketing Mishrag
🌐 What Is Edge SEO?
Edge SEO refers to making SEO-related changes at the edge of the network, closer to the user—without modifying your website’s core code.
It uses CDN (Content Delivery Network) platforms like Cloudflare, Akamai, or Fastly to:
-
Inject meta tags
-
Rewrite URLs
-
Pre-render content

Handle redirects

Improve page speed & indexing
Edge SEO = Technical SEO without developer delays.
