Grok
Grok is xAI’s AI assistant. xAI’s developer documentation describes a web search tool that lets Grok search the web and return citations, with options to restrict or exclude up to five domains. xAI has not published a crawler or webmaster guide comparable to OpenAI’s or Anthropic’s, so visibility advice is limited to general web visibility.
How does Grok search the web?
xAI’s API documents a web search tool; responses can include citations, and developers can set allowed_domains or excluded_domains (up to five each).[1]
Is there a Grok crawler to allow?
We found no xAI webmaster documentation naming a crawler user agent. Treat third-party claims about one with caution.
How can you check Grok visibility?
Run your prompt set in Grok as part of an AI visibility audit.
