What is Amzn-User?

Amzn-User is Amazon's assistant acting for a person. It fetches a page because someone asked an AI assistant a question right now. Each visit is a person waiting for an answer that may mention you.

The operator's description: Fetches live information when a person asks Alexa something; may not follow all robots.txt rules. (developer.amazon.com)

How do I block or allow Amzn-User?

With robots.txt, using the token Amzn-User. Amazon says it follows robots.txt only in part. To block the whole site:

User-agent: Amzn-User
Disallow: /

To allow it, use Allow instead of Disallow. Before blocking, weigh what it brings: every visit is a person asking an assistant for something; blocking takes you out of those answers.

How do I see whether Amzn-User visits my site?

In your server or CDN access logs, look for Amzn-User in the user agent. Google Analytics does not show these visits: agents do not run its JavaScript.

Anyone can copy the name in a user agent, so counting log lines is not enough. Knocklog reads your site's traffic on any host, confirms who is who, and shows how often Amzn-User came, which pages it read and what that brought you.

How do I know it is really Amzn-User?

Amazon does not publish a way to verify Amzn-User. Any program can use that name, so Knocklog shows these visits as “unverified”, never as genuine.
