What is YouBot?
YouBot is the crawler behind the You.com search engine. It discovers and indexes public pages so You.com can return current search results and cite web sources in AI answers. Its documented identity is YouBot/1.0 within a Chrome-style user-agent string.
The crawler can index HTML, PDFs, plain text, XML and RSS feeds, plus structured data embedded in pages. This is recurring search-engine crawling rather than a browser agent completing a transaction for one user. A visit usually means You.com is discovering or refreshing material for its search system.
You.com's YouBot documentation says the crawler adapts its rate, honors crawl-delay, and responds to server status codes. A 429 response reduces its request rate, while a 503 pauses crawling. The documentation says robots.txt is cached for 30 minutes, so a rule change may not appear immediately.
Indexing can make a page available for a You.com result or citation, though access alone does not guarantee placement. Disallowing YouBot prevents future compliant crawls of the blocked paths and can leave You.com without the latest version of that content.
No model-training use is documented for YouBot. Its stated job is search discovery and indexing. A rule aimed at this token controls the You.com search crawler, not a general opt-out from AI training by You.com or any other company.
You.com recommends Web Bot Auth for identity checks. Signed requests can be validated with the Ed25519 public keys at https://you.com/.well-known/http-message-signatures-directory. Its documentation also gives the reverse-DNS form youbot-{address}.search.you.com and publishes 68.67.112.0/24 as the source range, although the bot's listing does not mark YouBot as IP verified.
There is one source conflict to account for. You.com's documentation and this bot's metadata say YouBot respects robots.txt, but Cloudflare's bot record marks followsRobotsTxt false. Use the published robots rule as the operator-supported control, then check logs if compliance is important. The Web Bot Auth signature remains the stronger identity check.
