Add this group to the robots.txt file at the root of your site. It asks Amzn-SearchBot to stay out of every page.
User-agent: Amzn-SearchBot
Disallow: /To allow it explicitly, for example while a broader rule blocks other bots:
User-agent: Amzn-SearchBot
Allow: /How do I opt out of Amazon training but stay in its search?
Each Amazon user agent has its own token, so you can set them one by one. This file blocks Amazonbot and allows Amzn-SearchBot, Amzn-User. Every line comes from the rows in this dataset. Whether allowing a bot keeps you in a product is Amazon's call, so check each crawler's page. Amazon says Amzn-User may not follow robots.txt.
User-agent: Amazonbot
Disallow: /
User-agent: Amzn-SearchBot
Allow: /
User-agent: Amzn-User
Allow: /Does blocking Amzn-SearchBot affect AI answers?
Amazon: 'By permitting Amzn-SearchBot access to your website, your content is eligible to appear in search experiences such as Alexa.'
Each other Amazon user agent has its own robots.txt token, so a rule for Amzn-SearchBot does not cover them. See the related crawlers below.
Does Amzn-SearchBot follow robots.txt?
Yes. Amazon: honors robots.txt directives; if robots.txt does not mention it but allows other search bots, it follows those directives.
Robots.txt is a request, not a lock (RFC 9309).
What IP addresses does Amzn-SearchBot use?
Amazon publishes a list at https://developer.amazon.com/amazonbot/searchbot-ip-addresses/. We did not download or parse it. A request that claims to be Amzn-SearchBot but comes from outside that list is not Amzn-SearchBot.
