From our two studies of 29 October 2026: the 669 most visited websites and the 410 S&P 500 companies whose robots.txt we could read. 12 of the websites and 0 of the companies name Amzn-User in the file. The website study, the S&P 500 study.

The lines to copy

To shut it out
User-agent: Amzn-User
Disallow: /
To let it in
User-agent: Amzn-User
Allow: /

A crawler follows only the lines under the User-agent line that names it, and the lines under User-agent: * only when no line names it. So lines for one crawler do not change the rules for the others.

Amazon publishes the addresses it crawls from, so a request can be checked against them: the list.
