Frequently Asked Questions
Which AI crawlers should I allow?
At minimum, allow GPTBot (ChatGPT), PerplexityBot, and Google-Extended. Consider also allowing ClaudeBot, YouBot, and Cohere-AI. Each represents a major AI search or answer engine that could send traffic to your site.
Is it safe to allow AI crawlers?
Yes, legitimate AI crawlers respect robots.txt rules and crawl responsibly. They're operated by major companies like OpenAI, Anthropic, and Google. Allowing them is as safe as allowing traditional search engine crawlers.
What if I want to block AI but allow Google?
You can specifically block AI crawlers while allowing Googlebot. Add 'User-agent: GPTBot' followed by 'Disallow: /' for each AI bot you want to block, while keeping Googlebot allowed. Note this may impact future visibility.
How do I know if changes worked?
After updating robots.txt, use this tool to verify AI crawlers are now allowed. Changes take effect immediately for robots.txt. You can also use each platform's webmaster tools where available to confirm access.
