What is Amzn-User, and why is it visiting my website?

Amzn-User is a web crawler operated by Amazon that retrieves publicly accessible pages from websites. It is generally used by Amazon services to access web content for features such as link previews, integrations, and other service-level content retrieval tasks. Visits are typically triggered when Amazon systems need to fetch a page URL that appears in user activity or service workflows. Seeing Amzn-User in website logs is normal for publicly accessible pages that are referenced within Amazon platforms.

Is Amzn-User a legitimate bot, or is it commonly spoofed?

Amzn-User is an official crawler operated by Amazon. However, its user-agent string can be spoofed by automated scripts or malicious traffic attempting to appear as legitimate crawler activity. Attackers sometimes imitate well-known bots in order to bypass simple filters or hide scraping activity in server logs. Because of this, the User-Agent string alone is not sufficient to confirm that traffic is genuinely from Amzn-User. You can use Amazon's recommended methods mentioned below to verify a legitimate visit, or use RobotSense.io API to easily verify Amzn-User visits.

How can I verify that a request is really coming from Amzn-User?

You can use Amazon's recommended official methods to verify Amzn-User visits, these include: - IP range checks Do not use User-Agent based detection as that can be easily spoofed. Alternatively, you can use RobotSense.io API to easily verify Amzn-User and other bots from Amazon.

Should I allow or block Amzn-User on my website?

Allowing Amzn-User is generally optional and depends on whether you want Amazon services to access your publicly available pages. Allowing it may help ensure that links shared or referenced within Amazon services can retrieve page content correctly. If you are suddenly seeing too many visits, you can consider adding a small crawl-delay in your robots.txt before completely disallowing. Blocking may be appropriate in situations such as: - high server load caused by automated traffic - pages containing sensitive or restricted information - internal systems, APIs, or staging environments not intended for public access For most public websites, Amzn-User traffic is typically limited and does not cause operational issues.

How can I control or block Amzn-User using robots.txt or other methods?

You can add a rule in your robots.txt, as given above to control (crawl-delay) or disallow Amzn-User bot. Amzn-User crawler honors robots.txt directives, but it may take up to 30 days for your recent robots.txt changes to reflect properly. Also, you can use further controls in your WAF, or in RobotSense enforcement settings to manage the bot behavior.

How often does Amzn-User crawl websites, and can it impact server performance?

Amzn-User typically retrieves pages on demand rather than performing continuous large-scale crawling. Requests often occur when Amazon services need to access a specific URL, such as when a link is shared or referenced within a platform workflow. For most sites, the request rate is low and distributed over time. Performance impact is generally minimal, though dynamic pages or smaller servers may notice occasional additional requests. Some administrators choose to rate-limit or restrict it.

What happens if I block Amzn-User? SEO, visibility, and feature impact explained.

Blocking Amzn-User does not affect traditional search engine rankings because it is not a primary search engine crawler. However, blocking it may prevent Amazon services from retrieving page content when needed. Possible effects include: - Links shared within Amazon services may not generate previews - Certain Amazon integrations may not be able to retrieve page metadata - Content may not be accessible to Amazon systems that fetch external URLs For most websites, blocking Amzn-User has no direct impact on general web search visibility.

Does Amzn-User collect, scrape, or use my content for training or reuse?

No, Amzn-User bot has no officially documented AI purpose or republishing use-case. Amzn-User collected data may be used for purposes such as indexing, metadata extraction, and building datasets used across Amazon services.
