About Amazonbot

Amazonbot is Amazon's web crawler used to improve our services, such as enabling Alexa to answer even more questions for customers. Amazonbot respects standard robots.txt rules.

How Can I Identify Amazonbot?

In the user-agent string, you'll see “Amazonbot” together with additional agent information. An example looks like this:

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/600.2.5 (KHTML\, like Gecko) Version/8.0.2 Safari/600.2.5 (Amazonbot/0.1; +https://developer.amazon.com/support/amazonbot)


How Can I Control What Amazonbot Crawls on my Site?

Robots.txt: Amazonbot respects the robots.txt directives user-agent and Disallow. In the example below, Amazonbot won't crawl documents that are under /do-not-crawl/ or /not-allowed:

User-agent: Amazonbot               # Amazon's user agent
Disallow: /do-not-crawl/            # disallow this directory

User-agent: *                # any robot
Disallow: /not-allowed/      # disallow this directory


AmazonBot does not support the crawl-delay directive in robots.txt and robots meta tags on HTML pages such as “nofollow” and "noindex".

Link-Level Rel Parameter: Amazonbot supports the link-level rel=nofollow directive. Include these in your HTML like this to keep Amazonbot for following and crawling a particular link from your website.

<a href="signin.php" rel=nofollow>Sign in </a>


Verifying Amazonbot

Verify that a crawler accessing your server is the official Amazonbot crawler by using DNS lookups. This helps you identify other bots or malicious agents that may be accessing your site while claiming to be Amazonbot.

You can use command line tools to verify Amazonbot by following these steps:

  1. Locate the accessing IP address from your server logs
  2. Use the host command to run a reverse DNS lookup on the IP address
  3. Verify the retrieved domain name is a subdomain of crawl.amazonbot.amazon
  4. Use the host command to run a forward DNS lookup on the retrieved domain name
  5. Verify the returned IP address is identical to the original IP address from your server logs

For example:

$ host
789.56.34.12.in-addr.arpa domain name pointer 12-34-56-789.crawl.amazonbot.amazon.

$ host 12-34-56-789.crawl.amazonbot.amazon
12-34-56-789.crawl.amazonbot.amazon has address
