Free noindex checker.
Check one URL for page-level noindex evidence. This does not prove Google indexed the page; it tells you what this page served to the crawler, then points you to the next evidence layer.
When this is not enough
Noindex is only one signal. A full Index Pulse run compares this page evidence with sitemap membership, robots rules, canonical state, Search Console indexing status, and crawl history so the answer is not based on one isolated fetch.
