Amazon referrer traffic
Amazon referrals come from links on amazon.com and its regional domains — product listings, author pages, brand stores, and reviews. Because Amazon operates many country domains and applies referrer policy, the host varies by region and some clicks arrive as direct, so UTM tags help keep marketplace traffic attributable.
What this means
Amazon is a marketplace where your links can appear on product listings, author central pages, brand stores, and reviews. Clicks from those reach your site as referrals from an amazon domain.
This is marketplace traffic: it often reflects shoppers, authors' audiences, or brand-store visitors moving from a listing to your own site, which differs from search or social discovery.
Regional domains and referrer policy
Amazon runs many country marketplaces — amazon.com, amazon.co.uk, amazon.de, amazon.co.jp and others — so the referrer host varies by the shopper's region. Group these hosts together to see total Amazon-driven traffic rather than treating each country domain as a separate, unrelated source.
Amazon pages apply referrer policy that can downgrade or omit the Referer header, so some clicks arrive as direct. For links you control on Amazon-facing pages, add utm_source=amazon and utm_medium=referral so marketplace clicks stay attributable across regions even when the referrer is downgraded.
- Hosts you may see: amazon.com and regional domains (amazon.co.uk, amazon.de, etc.)
- Recommended tags: utm_source=amazon, utm_medium=referral
- Group regional domains together; referrer policy sends some clicks to direct
How it appears in analytics and logs
A referrer on an amazon domain means a visitor followed a link from a listing, author page, brand store, or review. Amazon's many country domains mean the host varies by region, and referrer policy sends some clicks to direct.
Diagnostic use case
Identify traffic arriving from Amazon listings, author, or brand pages across regional domains, and recover clicks that referrer policy would send to direct.
What WebmasterID can help detect
WebmasterID groups amazon-domain referrals as a marketplace channel across regional hosts and reconciles them with your UTM tags, so listing and author-page clicks stay distinct from generic referral.
Common mistakes
- Treating each Amazon country domain as a separate source instead of grouping them.
- Expecting every Amazon click to carry a referrer — policy sends some to direct.
- Leaving controllable Amazon-facing links untagged, losing clicks to direct traffic.
Privacy and accuracy notes
Attribution uses only the Referer host and any UTM parameters. No Amazon shopper or order is identified, and no purchase data is involved. WebmasterID records the channel, not the person.

- Gumroad referrer traffic
Gumroad referrals come from creator and product pages on gumroad.com, a platform for selling digital products. Clicks from a Gumroad page or profile can reach your site as gumroad.com referrals, but embedded checkouts and redirects can obscure the path, so UTM tags help keep creator-commerce traffic attributable.
- Referrer grouping into channels
Analytics platforms do not report every raw referrer separately — they map hosts into channel groups such as organic search, paid, social, referral, email, and direct. Understanding the default rules explains why a click ends up in one bucket versus another, and why a custom source can be misfiled until you adjust the grouping.
- Referrer-Policy and missing referrers
Referrer-Policy is the web standard that controls how much of the referrer a browser sends with a request. Site owners set it via an HTTP header or a meta tag, and modern browsers default to a privacy-leaning value. Understanding the policy values explains why so many referrers arrive trimmed to the origin or missing entirely.
