Why is robots.txt Important for GEO?
The robots.txt file tells search engines and AI crawlers which pages can be accessed. If you block AI crawlers, your content cannot be indexed and cited by AI search engines.

FAQ
Q: Does allowing AI crawlers affect SEO?
A: No. AI crawlers and traditional search engine crawlers are independent - allowing AI crawlers doesn't affect Google rankings.
Q: Should I allow training crawlers?
A: It depends on your strategy. Allowing training can help AI better understand your brand, but if you're concerned about content being used for training, you can allow only search crawlers.
Q: How long until changes take effect?
A: Crawlers periodically re-read robots.txt, usually taking effect within hours to days.
Summary
Properly configuring robots.txt is the first step in GEO optimization. Ensure AI crawlers can access your website so your content has the opportunity to be cited and recommended.
