What the generated file does
- Every
Disallowpath is matched from the start of the URL path./admin/blocks/admin/usersbut not/blog/admin/.*matches any characters and$anchors the end. - An
Allowline wins over a shorterDisallow, so it works as an exception inside a blocked folder. - AI crawlers you block get their own
User-agentgroup withDisallow: /. A crawler with its own group ignores the*group. Google-ExtendedandApplebot-Extendedare usage tokens, not crawlers. Blocking them does not affect Google Search or Apple search. The AI bot checker lists what each crawler is for.
robots.txt does not remove pages from Google
It stops crawling, not indexing. A blocked URL that other pages link to can still show up in results without a description: Search Console then reports Indexed, though blocked by robots.txt. To keep a page out of the index, leave it crawlable and add noindex; check it with the noindex checker.
