Edge SEO
In one sentence
Applying changes at the CDN layer, before the request reaches the origin server.
Analogy Mental model
Putting the sign at the entrance to the estate rather than inside each building. The courier sees it before arriving.
In practice What you actually do
Workers and edge functions can rewrite a title, add a header, inject structured data, or handle a redirect without a deployment. Useful for tests, for platforms where the origin cannot be touched, and for emergencies.
Where people get burned Pitfalls
Somebody else's infrastructure now sits in the critical path, and their outage becomes yours. Anything permanent belongs in the codebase, where it is versioned and reviewable.
