Why pages are or are not indexed, from Search Console's URL Inspection API, grouped by Google's own coverage wording (Not found (404), Page with redirect, Excluded by 'noindex' tag, Blocked by robots.txt, Crawled - currently not indexed, Discovered - currently not indexed, Alternate page with proper canonical tag…). The URL set is first-party: the site's sitemaps, pages seen in search over 90 days, and paths a verified Googlebot requested at the edge in 30 days. Each group carries its URLs with referring pages, sitemap membership, declared and Google-chosen canonicals, last crawl and fetch state, plus the fix for that reason; facts list 404s still linked to, redirecting URLs still in a sitemap, canonical disagreements and noindex pages a sitemap submits.
