HTTP status checker
Everything else in this product assumes the URL returned a document. A 404, 410 or 5xx means there is nothing to rank, share or preview.
What we measure
The status of the final response after the fetch follows redirects. You see that code and the final URL. Soft-404s that return 200 with an error page are a different bug — they pass this check and fail the others.
What to do
Pages you want indexed must return 200. Moved URLs should 301 to the canonical, not 302 in a loop. Gone URLs should 404 or 410, not a 200 empty template.
