Search index crawler from You.com

# YouBot

In short

YouBot is You.com's search index crawler. The token to write in robots.txt is YouBot. The operator publishes nothing a site can check. 10.3 percent of 5,938 top-10,000 sites with a parsed robots.txt disallow it at the root (crawl of 2026-11-04). Verisoul reports YouBot signs its requests, but You.com publishes no key directory or documentation we could read.
