Robots.txt best practices

Keep your robots.txt simple: use it to block low‑value or duplicate URLs, not to hide sensitive data, and always test it in Google Search Console before deploying.[web:758][web:759][web:767]

  • Start with basic User-agent and Disallow rules before adding complexity.[web:761][web:770]
  • Use Sitemap lines to highlight your XML sitemaps to crawlers.[web:758][web:761]
  • Avoid unsupported directives; stick to the fields Google documents, like User-agent, Disallow, Allow, and Sitemap.[web:759][web:768][web:747]

When to use robots.txt for SEO

Robots.txt is best for blocking infinite spaces, admin back‑ends, or low‑value duplicate pages so crawlers can focus on important content instead of wasting crawl budget.[web:767][web:764]

Common mistakes to avoid

  • Blocking the entire site with Disallow: / when you meant to restrict only a folder.[web:762][web:770]
  • Trying to deindex pages only with robots.txt instead of using noindex tags or removing them from sitemaps.[web:758][web:765]
  • Forgetting to update robots.txt after site migrations or major URL structure changes.[web:761][web:770]
