What is Amzn-SearchBot?
Amzn-SearchBot is Amazon's search crawler: it indexes pages for search results. In Amazon's words:
“Amzn-SearchBot is used to improve search experiences in Amazon products and services.”
“Amzn-SearchBot does not crawl content for generative AI model training.”
“If robots.txt files don’t mention Amzn-SearchBot but allow other search bots, Amzn-SearchBot will crawl in accordance with the robots.txt directives given to other search bots.”

How to block Amzn-SearchBot in robots.txt
Add this group to the robots.txt file at the root of your domain to block Amzn-SearchBot from your whole site:
User-agent: Amzn-SearchBot Disallow: /
To block only part of your site, list those paths instead:
User-agent: Amzn-SearchBot Disallow: /private/
A group that names Amzn-SearchBot replaces your User-agent: * rules for it entirely (RFC 9309). If your catch-all group blocks paths that Amzn-SearchBot should also stay out of, repeat them in its group. To let Amzn-SearchBot in while a catch-all rule blocks others:
User-agent: * Disallow: / User-agent: Amzn-SearchBot Allow: /
“Automated crawling from these listed user agents respects the Robots Exclusion Protocol, honoring the user-agent and the allow/disallow directives.”
What happens if you block Amzn-SearchBot?
“By permitting Amzn-SearchBot access to your website, your content is eligible to appear in search experiences such as Alexa.”
