Amzn-SearchBot
Amazon · AI search · robots.txt: Yes
Crawls the web for search experiences in Amazon products such as Alexa; Amazon says it does not crawl content for generative AI model training.
Block Amzn-SearchBot
User-agent: Amzn-SearchBot
Disallow: /Amazon says allowing Amzn-SearchBot makes your content eligible for search experiences such as Alexa, so blocking it gives that up. It has no training role to opt out of.
Allow Amzn-SearchBot
User-agent: Amzn-SearchBot
Allow: /An allow group only changes anything if a broader rule would block Amzn-SearchBot. Under the robots.txt standard (RFC 9309, section 2.2.1) a crawler follows the group that names it and uses the User-agent: * group only when no group does — so this group lets it in even if your * group says Disallow: /. Token matching is case-insensitive.
Put these lines in /robots.txt at the root of each host (each subdomain has its own file). robots.txt is a request to well-behaved crawlers, not access control.
