A robots file is evaluated per origin (scheme + hostname + port). That means a file served from a subdomain only governs crawling of that subdomain. is correct to point out that the main domain is unaffected unless the same content is also reachable under the main domain URLs (for example via aliasing, reverse proxying, or serving identical pages from both hosts).

Crawlers fetch the file from the root of each host (origin)/robots.txt, so http and https and each subdomain need their own file. Major engines support Allow/Disallow rules and simple pattern matching, but behavior can differ in edge cases; authoritative guidance is available from Google's robots documentation and robotstxt.org.

Quick checklist and troubleshooting:

  • Host a robots file at the subdomain root and confirm it returns 200 OK when requested by that host.
  • Verify that the main domain does not expose the same pages under its own URLs; if it does, use 301 redirects or canonical tags to enforce the preferred host.
  • Use Search Console tools and server logs to confirm which robots file Googlebot is reading and whether pages are being crawled/indexed.
  • If the goal is removal from the index, note that blocking with robots instructions does not reliably prevent indexing. For guaranteed removal, allow crawling and use a crawlable noindex directive or use proper access controls; robots exclusions are not a security mechanism.

As tried to explain, Allow means permitted crawling and Disallow blocks crawling. Keep robots files simple, test changes, and follow the official docs for exact parsing rules.

This will affect your main domain only if it is accessible through your main domain url also.
e.g. yourmaindomain .com/robots.txt

Allow mean do you allow to check your website to search engines if you are disallow it's mean you are disable allow to search engine to check your website:)
