How to Use robots.txt for SEO

robots.txt controls which crawlers can access which parts of your site. Use it to save crawl budget by blocking low-value pages and to control AI training data access. In 2026, with AI crawlers proliferating, robots.txt has become critical for controlling which AI systems can train on your content.

Note: OAI-SearchBot and PerplexityBot are real-time search crawlers -- blocking them reduces AI search visibility. GPTBot and Google-Extended are training crawlers -- blocking them prevents content use in AI training without affecting real-time AI search.

Frequently Asked Questions

Does blocking Googlebot in robots.txt hurt rankings?+
Yes, completely. Blocked pages cannot be indexed or ranked. Only block URLs you genuinely want excluded: admin pages, internal search results, duplicate parameter URLs, and staging environments. Never block CSS or JS files -- Googlebot needs them to render and evaluate pages.
Should I block AI crawlers?+
It depends on your goals. Allowing AI search crawlers (OAI-SearchBot, PerplexityBot) helps you appear in AI search results. Blocking training crawlers (GPTBot, Google-Extended) prevents your content being used in model training. Most publishers allow search crawlers while blocking training crawlers.
