Amazonbot
Amazonbot is an official web crawler operated by Amazon. Its primary mission is to gather and index information from the web to improve Amazon's services, with a special focus on enhancing the ability of its virtual assistant, Alexa, to answer user questions accurately. If your website's content is referenced by Alexa, it can increase awareness of your brand.
What is Amazonbot?
Amazonbot is the dedicated web crawler developed and operated by Amazon. Its main function is to systematically browse the internet to collect information that enhances various Amazon services, particularly the question-answering capabilities of Alexa. The bot identifies itself with a clear user-agent string, such as Mozilla/5.0 (...); Amazonbot/0.1; +https://developer.amazon.com/support/amazonbot
. Amazon provides a verification system for its crawler; administrators can confirm its legitimacy through DNS lookups, which should resolve to a crawl.amazonbot.amazon
subdomain.
Why is Amazonbot crawling my site?
Amazonbot is visiting your website to gather publicly available information that can improve how Amazon's services, especially Alexa, respond to user queries. It looks for factual information, product details, and other high-quality content that could be valuable for answering questions. The frequency of its visits depends on the relevance and update schedule of your content. This crawling is considered authorized, as the bot respects standard web protocols like robots.txt
, but it will access public content unless specifically instructed not to.
What is the purpose of Amazonbot?
The core purpose of Amazonbot is to improve Amazon's services, primarily by enhancing Alexa's knowledge base. The web content it collects and indexes allows Alexa to provide more accurate and natural-sounding answers when users ask questions via Alexa-enabled devices. For website owners, having your content crawled by Amazonbot can increase your information's visibility within the Amazon ecosystem. If Alexa references your content when answering a question, it can potentially drive awareness of your brand or expertise.
How do I block Amazonbot?
To prevent Amazonbot from accessing your website, you can add a specific disallow rule to your robots.txt
file. This is the standard method for managing crawler access to your site.
Add the following lines to your robots.txt
file to block Amazonbot:
User-agent: Amazonbot
Disallow: /
