YouBot — You.com crawler
YouBot is the crawler operated by You.com to support its search and AI assistant. Its robots.txt token is YouBot. Public documentation is limited in places, so specifics that cannot be confidently sourced are marked partially verified rather than guessed.
What this means
YouBot is the crawler You.com uses to support its search and AI assistant experiences. It appears in logs as an automated fetcher carrying the YouBot token.
Where You.com's public documentation is incomplete, this entry describes the stable identification pattern and avoids asserting specifics that cannot be confidently sourced. Treat unverified claims about YouBot's exact scope with caution.
How YouBot identifies itself
YouBot uses the robots.txt user-agent token YouBot. Its user-agent string contains that token together with a self-identifying URL. Match on the stable token rather than a full version string.
The user agent is a claim and can be copied. Where verification guidance is not clearly published, do not invent IP ranges; identify YouBot by its token and treat trust-sensitive decisions conservatively.
- robots.txt token: YouBot
- Operated by You.com for search and assistant features
- Some specifics: not fully documented publicly
robots.txt considerations
To disallow YouBot site-wide, target its token:
User-agent: YouBot Disallow: /
YouBot is expected to honour robots.txt as a compliant crawler, but treat the rule as a request rather than enforcement. robots.txt is never an access-control boundary.
How it appears in analytics and logs
A request carrying the YouBot token is You.com's crawler fetching a URL — a bot event, not a human visit. Identify it by the token; treat specifics not covered by clear documentation conservatively.
Diagnostic use case
Identify YouBot activity in logs by its token and set robots.txt policy for You.com's crawler, treating undocumented specifics with caution.
What WebmasterID can help detect
WebmasterID classifies YouBot server-side by its token and surfaces it on the bot-intelligence and AI-visibility surfaces, so you can see You.com crawl activity per page without parsing logs.
Common mistakes
- Asserting documented behaviour where You.com's public docs are sparse.
- Inventing IP ranges to verify YouBot.
- Counting crawler hits as human sessions.
Privacy and accuracy notes
Detection uses only the request user-agent. No human identity is involved. WebmasterID records the crawl as a bot event, separate from human analytics, and never attaches it to a visitor profile.
