How to block Bedrockbot

Bedrockbot is the crawler associated with Amazon Bedrock for fetching web content. This page shows how to disallow Bedrockbot in robots.txt, how it differs from Amazonbot, and how to confirm the rule is honoured.

Partially verified

robots.txt rule

To disallow Bedrockbot site-wide, target its token in its own group:

User-agent: Bedrockbot Disallow: /

Confirm the exact token against your access logs and Amazon's published guidance before relying on it. Match the documented token rather than a full version string, and remember robots.txt is honoured by compliant crawlers, not enforced.

Bedrockbot vs Amazonbot

Amazon operates more than one crawler. Bedrockbot relates to Amazon Bedrock, while Amazonbot is Amazon's general web crawler — they are separate tokens with separate purposes. Blocking one does not block the other.

If your intent is to decline Amazon's AI crawling broadly, target each relevant token explicitly in robots.txt rather than assuming a single rule covers all of Amazon's bots.

How it appears in analytics and logs

Bedrockbot hits indicate Amazon Bedrock-related crawling reached a URL. It is a bot event, not a human visit, and should be counted as AI-crawler activity.

Diagnostic use case

Opt your site out of Bedrockbot's crawling while keeping or separately deciding policy for Amazonbot and other AI crawlers.

What WebmasterID can help detect

WebmasterID classifies Bedrockbot as an AI crawler distinct from Amazonbot, so you can confirm a block lands and see Bedrock crawl coverage separately.

Common mistakes

Privacy and accuracy notes

The rule matches the Bedrockbot token only. No visitor identity is involved; robots.txt is a request to compliant crawlers rather than enforcement.
