Overview
YouBot is a search crawler from You.com used for search indexing, URL discovery, page rendering, result freshness, and search-quality checks.
Its primary user-agent pattern is YouBot; a representative HTTP user-agent is Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; YouBot/1.0; +https://docs.you.com/youbot env:prod) Chrome/X.X.X.X Safari/537.36.
YouBot is Unverified at the identity-evidence level. The listed identity remains useful for detection, but this record does not currently contain authoritative evidence sufficient to authenticate the identity claim.
YouBot is marked as not reliably governed by robots.txt directives; use server-side rules if the traffic should be restricted.
YouBot can usually be allowed after confirming the source and monitoring request volume.

Behavior and handling
- Common Use
- YouBot is used for search indexing, URL discovery, page rendering, result freshness, and search-quality checks.
- Detection Notes
- YouBot traffic is primarily detected by the `YouBot` user-agent pattern; a representative HTTP user-agent is `Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; YouBot/1.0; +https://docs.you.com/youbot env:prod) Chrome/X.X.X.X Safari/537.36`. Compare source IPs, reverse DNS, request paths, and crawl cadence with You.com infrastructure before trusting the traffic.
- Respects robots.txt
- No
- Spoofing Risk
- YouBot has medium spoofing risk because user-agent strings can be copied; pair the match with DNS, IP, behavior, or operator evidence.
- Risk
- Safe
- Recommended Handling
- Depends
Rules and controls
- Robots.txt Snippet
