Why this matters for AI agents

Most sites inherit a wildcard User-agent: * rule into AI traffic without realising. ChatGPT, Claude, and Perplexity respect explicit agent rules first; if you have blocked *, you have blocked them too.

Agents that get a 403 or a wildcard disallow do not appear in their answers. AgentSpeed scores every site against robots_txt.allows_known_agents. Passing it is the cheapest single change you can make for AI visibility.

Common fixes
Wildcard disallow blocks every AI crawler
Replace User-agent: *\nDisallow: / with named entries for each agent you actually want to block. Or keep the wildcard and add agent-specific Allow: / blocks below it.
Want search but not training
Add Content-Signal directives: Allow-Crawl-For-Search, Disallow-AI-Training. Compliant agents will honour the policy.
Block Bytespider but keep Google
Add an explicit User-agent: Bytespider\nDisallow: / block. Wildcard rules then no longer apply to Bytespider.
/llms.txt accidentally blocked
Make sure no Disallow: /llms.txt rule exists. Agents that follow robots.txt strictly will skip the file if it is disallowed.

FAQ
Why do I need to allow GPTBot?
GPTBot is OpenAI’s crawler used to discover and ground answers from your site. Blocking it means ChatGPT will not cite you when users ask about your product.
Does blocking Bytespider affect Google?
No. Bytespider is ByteDance’s crawler. It has nothing to do with Googlebot. You can block one without affecting the other. That is exactly what agent-specific rules are for.
What is Content-Signal?
Content-Signal is a Cloudflare-led extension to robots.txt that lets you grant fine-grained consent: search vs inference vs training vs summarisation. Compliant agents honour the directives. We surface them when present.
Will allowing AI bots affect my SEO?
No. Allowing GPTBot, ClaudeBot, etc. is independent of how Googlebot indexes your site. Most SEO impact comes from how your content is structured, not which crawlers you allow.
Why does my site allow GPTBot but not ClaudeBot?
You have an agent-specific Disallow for ClaudeBot somewhere, usually inherited from a copy-pasted snippet. Audit your robots.txt for any User-agent: ClaudeBot blocks.
Can I see the robots.txt other sites publish?
Yes. /robots.txt is public by definition. Try the example URLs above to compare how OpenAI, GitHub, and Stripe configure theirs.
