Robots Exclusion Protocol (RFC 9309 Standards)
The Robots Exclusion Protocol (REP) provides webmasters a mechanism to indicate to automated web crawlers which URL paths are accessible for indexing.
Key Directives
- User-agent: Specifies target crawler string (e.g.
*,Googlebot,GPTBot). - Disallow / Allow: Defines relative URL path rules matching prefix patterns or wildcards (
*,$). - Sitemap: Points crawlers directly to XML sitemap locations (e.g.
https://example.com/sitemap.xml). - Crawl-delay: Non-standard directive instructing search engines to throttle request frequency per second.
