Amzn-User
Amazon’s user-triggered fetch for fresh answers in Alexa and related products. Discovery here is being readable when Amazon needs the live page.
- Operator
- Amazon
- Traffic type
- AI answers
- Verification
- Not independently verifiable
- robots.txt
- Usually honors robots.txt
Usually means: Live fetches when someone asks an assistant a question. If these bots cannot reach the page, you cannot be the citation in that answer.
User-agent
robots.txt and most WAF rules match the token, not the full Mozilla string. Operators often wrap Amzn-User in extra product or version text.
Amzn-User
What Amzn-User does
Amzn-User fetches a page because an Amazon assistant experience needs current content. It is separate from Amazonbot (broader crawl) and Amzn-SearchBot (search eligibility).
How to get discovered
Allow Amzn-User, keep titles and product facts in HTML, and do not require a marketplace session to read public specs or help articles.
Why Amzn-User might skip you
Geo fences, bot challenges, or a robots file that Disallows Amazon* after a poorly copied AI-block template.
robots.txt rule
Allow this token on public pages you want retrieved or cited. A CDN “Block AI bots” toggle can still 403 it after robots.txt says Allow.
# Keep Amzn-User eligible to fetch this site
User-agent: Amzn-User
Allow: /Amazon has not published a machine-readable range file for this token. Do not treat the user-agent alone as proof of identity.
JavaScript: render behavior is not documented.
Other Amazon bots
Training, search, and user-fetch tokens from the same operator are not interchangeable. Allow the discovery path even when you opt out of training.
Amzn-User FAQ
What is Amzn-User?
Amzn-User fetches a page because an Amazon assistant experience needs current content. It is separate from Amazonbot (broader crawl) and Amzn-SearchBot (search eligibility).
Should I allow Amzn-User in robots.txt?
Yes if you want Amazon to be able to fetch and cite this site. Blocking Amzn-User is how pages stay invisible to that product even when Googlebot still crawls them.
How do I know a request is really Amzn-User?
Amazon has not published a range file for this token. Treat the user-agent as a claimed identity, and do not build a hard IP allowlist from blog posts or screenshots.
Letting Amzn-User in is the start. Getting cited is the job.
