To work, the page must be accessible to crawlers and not blocked by `robots.txt`. Implementation options include adding `\u003cmeta name=\"robots\" content=\"noindex\"\u003e` to a page's `\u003chead\u003e` or using the `X-Robots-Tag: noindex` HTTP header. Crawlers must revisit the page after `noindex` is added, which can be sped up using the URL Inspection tool. The rules can be tested using the URL Inspection tool.\n"]]
