Do not block discovery by mistake
A crawler has to fetch a page or file to see a meta robots tag or X-Robots-Tag header. Robots.txt blocking and noindex solve different problems.

Create robots meta tags and X-Robots-Tag headers for HTML pages or non-HTML files. OpenWebmaster also checks pasted directives for obvious conflicts, unsupported tokens, and preview-control mistakes.
No sample noindex result, crawler-removal promise, AI-training guarantee, ranking impact, traffic claim, or manufactured robots score appears before you provide settings or source.

Use noindex for URLs that should stay accessible but out of search. Keep important pages crawlable and avoid adding restrictive directives site-wide by accident.
After publishing, inspect the final HTML and headers with the URL indexability checker and HTTP header checker, then monitor Search Console or Bing Webmaster Tools separately.
