“Avoid Unnecessary Executions”

➔ Not every HTTP request needs a Worker ➔ Avoid
running Workers on non-HTML assets ➔ Keep executions focused on key SEO tasks

“Test in Staging Before Deployment”

➔ Always test before launching changes ➔ If CF is
not active on staging, use test pages ➔ Monitor responses carefully — headers, status, and timing

Key Takeaways

Quick Unblocker Not a Long Term Measure

Use ChatGPT

Devs are Friends, not Enemies Unless it’s a Friday Rollout
