YouBot is operated by You.com, an AI-first search engine that pairs traditional results with an AI assistant. Its crawler indexes the web to serve both those search listings and the assistant's cited answers, so it functions as a live search and answer crawler.
The consequence of blocking is that You.com cannot list or cite your pages, removing you from both its search results and any AI answers its assistant generates. For sites that value visibility in AI-native search engines, keeping YouBot allowed keeps that channel open.
How to check and control it

FAQ
What does YouBot power?
YouBot crawls the web for You.com, an AI-first search engine. The content it gathers feeds both You.com's standard search results and the cited answers produced by its AI assistant, so allowing it keeps your pages eligible across both of those surfaces.
Will blocking YouBot affect other search engines?
No. YouBot is specific to You.com. Blocking it removes your content only from You.com's search and assistant. Other engines like Google or Bing use their own crawlers and rules, so their indexing of your site is unaffected by a YouBot Disallow.
