Playbook: pages that get found and never indexed

Playbook: pages that get found and never indexed
"Found, not indexed" means the address is known and the crawler decided it was not worth fetching yet. That is a priority signal, not a bug.
Work through it in this order:
— Check the server. Slow or unstable responses make the crawler back off on its own. Cheapest fix, most ignored.
— Check internal links to the page. Zero or one link from somewhere deep tells the crawler precisely how much you value it.
— Check for near-duplicates. If you have many pages built from one template with a word swapped, the pattern has already been seen.
— Confirm the sitemap includes it and that it returns 200.
— Then improve the page. Something on it should exist nowhere else.
— Request indexing once. Requesting repeatedly does nothing except make you feel busy.
If it still does not get indexed after all that, take the hint. Not every page deserves to exist.
