What an AI assistant fetcher does
An assistant fetcher visits only when someone asks an AI assistant a question that needs your page. Each visit stands for a real person, often one who is about to click through, so blocking it usually costs you readers.
Amazon says it may not follow every robots.txt rule.
Block or allow Amzn-User in robots.txt
Add one of these to the robots.txt file at the root of your domain. Crawlers read it before they fetch anything else.
Block Amzn-User
User-agent: Amzn-User
Disallow: /Allow Amzn-User

Questions, answered.
Amzn-User is an AI assistant fetcher run by Amazon. Fetches up-to-date pages for a person's request, such as an Alexa question.
Not always. Amzn-User fetches pages for a person, and Amazon says robots.txt may not apply. Amazon says it may not follow every robots.txt rule.
Add "User-agent: Amzn-User" and "Disallow: /" to your robots.txt. Since robots.txt may not stop it, block it at your firewall or server too.
Check the request's IP address against the list Amazon publishes. A user agent alone proves nothing, since any script can copy it.
Indirectly. Amzn-User opens your page because a person asked about it, and the answer can link back to you.
Usually not. Each visit stands for a person asking about your page, so blocking Amzn-User turns readers away.
