Amzn-User

Amzn-User fetches individual pages in direct response to a user action or an Amazon application’s request — for example, retrieving up-to-date information to answer an Alexa query. Amazon’s own documentation states this crawler is not used to train generative AI models.

A robots.txt limitation worth knowing

Amazon’s own documentation states that Amzn-User “may not follow all robots.txt directives” because its requests are triggered by a specific person, not a bulk crawl. A Disallow rule aimed at this token is not a reliable way to prevent this specific page from being fetched on a user’s behalf — see /limitations for what a robots.txt rule can and cannot guarantee more generally.

Site-owner controls

A robots.txt rule for Amzn-User may not be honoured consistently, per Amazon’s own documentation above. It does not affect Amazonbot (Amazon’s mixed-use, possibly-training crawler) or Amzn-SearchBot (search-experience indexing, which does honour robots.txt), both documented separately.

Related crawlers

Amazon documents Amzn-User alongside Amzn-SearchBot (search-experience crawling, also excluded from AI training) and Amazonbot (mixed use, including possible AI training) on the same page. See Amazonbot vs. Amzn-SearchBot vs. Amzn-User for a side-by-side comparison.
