Amzn-User: Amazon's Answer Crawler
What is Amzn-User?
Amzn-User is the Amazon fetcher that retrieves a live web page when a person asks Alexa something that needs current information. Amzn-User fetches because a person asked, so Amazon documents that it may not follow every robots.txt directive, unlike Amazonbot and Amzn-SearchBot.
Key facts
- Amzn-User is operated by Amazon, and its purpose is live fetch: fetches a page in real time because a person asked.
- The user agent for Amzn-User is documented by Amazon and contains the token Amzn-User.
- The robots.txt token for Amzn-User is Amzn-User, and Amazon states that rule may not apply, because a person starts the request.
- Amzn-User never sends a visitor to your site, and Amzn-User attaches no citation when it uses your content.

What this looks like in your logs
203.0.113.42 - - [25/Oct/2026:09:14:07 +0000] "GET /pricing HTTP/1.1" 200 18432 "-" "Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; Amzn-User/0.1) Chrome/W.X.Y.Z Safari/537.36"
The part that identifies the request is the token Amzn-User, inside the quoted user-agent field at the end of the line. Everything before it is the ordinary shape of a Common Log Format entry, and the address shown is a documentation address rather than one Amazon uses.
What Amzn-User does not do
Amzn-User does not send you a visitor, and it attaches no citation, so a read by it can never turn into a click.
Amzn-User does not crawl on a schedule, because it only requests a page when a person has already asked something that needs it.
Amazon publishes no crawl frequency for Amzn-User, so any schedule you read elsewhere is somebody's estimate rather than a documented figure.
How Kymo classifies it
Kymo files Amzn-User under Amazon as ai_answer, classified from the HTTP request on the server rather than from anything running in a browser.
A hit from Amzn-User counts in the reads on the AI Traffic page. An answer crawl is the only kind made for one person's question, so it is the only kind counted beside the people AI sent you.

Allow it or block it
A robots.txt rule for Amzn-User may not be followed, because Amazon treats its requests as user-initiated. Amazon documents that Amzn-User does not crawl content for generative AI model training. To stop it reliably, block its published IP ranges at the firewall rather than relying on robots.txt.
| Allow it if | Block it if |
|---|---|
| You want Amazon to read your live page when a person asks about you, which is the crawl most likely to send a real visitor. | You do not want your page read during a live question. Check the compliance row first: a fetcher started by a person may need an edge rule rather than a robots.txt rule. |
robots.txt directives
Both blocks below address Amzn-User only. Rules for one token never apply to another, even from the same operator.
Allow Amzn-User
User-agent: Amzn-User Allow: /
Block Amzn-User
User-agent: Amzn-User Disallow: /
Questions
How do I know a request claiming to be Amzn-User is genuine?
Amazon publishes the IP ranges Amzn-User uses at https://developer.amazon.com/amazonbot/live-ip-addresses/. Check the requesting address against that file. A user-agent string alone proves nothing, because anyone can send one.
Does blocking Amzn-User also block Amazonbot?
No. Amzn-User and Amazonbot are separate tokens, and Amazon treats each one on its own. A rule naming Amzn-User leaves Amazonbot free to carry on collecting your content for Amazon model training. To stop that as well, name Amazonbot in a rule of its own.
Will I see Amzn-User in Google Analytics?
No. Google Analytics runs a JavaScript tag in a visitor's browser, and Amzn-User reads your HTML and leaves without running any script. Server-side logging is the only way to record it.
Does Amzn-User send traffic back to my site?
No. Amzn-User takes content and sends nothing back. A hit appears in your logs as a request with no visitor behind it.

Amzn-User arrives because a person just asked Amazon something, and a browser tag never runs in time to record the moment.
Kymo reads the HTTP request on your server, so a crawler that never runs JavaScript is still recorded. You see which bots reached the site, which pages they took and how often, next to your human traffic.
