How it works
A robots.txt file uses simple directives (Allow/Disallow) to specify rules for crawlers, either for all bots or for specific named user agents. It’s a voluntary standard — compliant crawlers respect it, but it is not a technical access control.
Why it matters for responsible scraping
Reputable scraping providers check and honor a site’s robots.txt rules as part of operating ethically and within a site’s stated preferences, alongside reviewing terms of service.
