Amazon Web Search crawlers
This page describes how webmasters can control Amazonbot, Amzn-SearchBot, and Amzn-User interactions with their site. Each user agent setting is independent of the others, and may take ~24 hours for our systems to reflect changes.
Amazonbot
Amazonbot is used to improve our products and services. This helps us provide more accurate information to customers and may be used to train Amazon AI models.
- Example User Agent String:
Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; Amazonbot/0.1) Chrome/W.X.Y.Z Safari/537.36 - Published IP Addresses: https://developer.amazon.com/amazonbot/ip-addresses/
Amzn-SearchBot
Amzn-SearchBot is used to improve search experiences in Amazon products and services. By permitting Amzn-SearchBot access to your website, your content is eligible to appear in search experiences such as Alexa. 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. Amzn-SearchBot does not crawl content for generative AI model training.
- Example User Agent String:
Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; Amzn-SearchBot/0.1) Chrome/W.X.Y.Z Safari/537.36 - Published IP Addresses: https://developer.amazon.com/amazonbot/searchbot-ip-addresses/
Amzn-User
Amzn-User supports user actions, such as responding to Alexa queries that require up-to-date information. For example, when a customer asks a question, Amzn-User may fetch live information from the web to provide accurate answers on the user’s behalf. Because actions taken by Amzn-User can be initiated by a user, it may not follow all robots.txt directives.Amzn-User does not crawl content for generative AI model training.
- Example User Agent String:
Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; Amzn-User/0.1) Chrome/W.X.Y.Z Safari/537.36 - Published IP Addresses: https://developer.amazon.com/amazonbot/live-ip-addresses/
Our Approach to Robots.txt
Automated crawling from these listed user agents respects the Robots Exclusion Protocol, honoring the user-agent and the allow/disallow directives. They will fetch host-level robots.txt files or use a cached copy from the last 30 days. When a file can’t be fetched, they will behave as if it does not exist.
These user agents attempt to read robots.txt files at the host level (for example example.com), so they look for robots.txt at example.com/robots.txt. If a domain has multiple hosts, then they will honor robots rules exposed under each host. For example, if there is also a site.example.com host, they will look for robots.txt at site.example.com/robots.txt.
When these user agents access web pages they respect the link-level rel=nofollow directive, and page level robots meta tags of noarchive (do not use the page for model training), noindex (do not index the page) and none (do not index the page). They do not support the crawl-delay directive.
