Edge routing, cache policies, and regional rollouts can silently slow SEO landing pages. This checklist keeps your edge stack accountable.
Collect cache hit ratio, TLS handshake time, and TLS version adoption per POP. Slow edge TLS is often misdiagnosed as bad LCP.
Expose stale-if-error metrics so you can see when fallbacks hide origin outages.
Treat Workers/Functions like code: git tags, rollout waves, and automated rollbacks. Annotate MakeWebsite.fast reports with deploy hashes.
When SEO teams launch 100+ landing pages, ensure the same version of edge logic handles them, or you will chase phantom regressions.
Pipe edge logs into the same data warehouse that holds vitals, so you can correlate latency spikes with deployments.
Set up runbooks that tell marketing what to do when a POP degrades — usually pausing paid campaigns in that region until cache recovers.
If you rely on global traffic or expect sudden virality, yes. Blind spots get expensive fast.
Use RUM beacons and synthetic tests per region to approximate the missing telemetry, then push your vendor for native support.
