Common questions
What should I enter?
Use a public production URL or the exact text requested by the form. Do not enter private admin pages, tokens or internal addresses.
Is every recommendation critical?
No. Fix issues that block crawling, indexing, page understanding or the user path first. Treat the rest as improvements.
How do I confirm the fix?
Run the same check again for the same URL after publishing the change.
