Amazon Attribution is Amazon’s free measurement solution for the question sellers could never answer: what does my off-Amazon marketing actually do inside Amazon. It measures how search, social, display, video, email and influencer campaigns running outside Amazon drive product views, add-to-carts and sales on Amazon, using attribution tags on your ad destination links. It lives in the Amazon Ads console under Measurement and Reporting. The Amazon R&D and Causal Inference team considered one of the best in the world with exceptional research and industry ties. They made significant effort to open-source their work to the rest of the community.
What Amazon Attribution is (and isn’t)
Amazon Attribution measures off-Amazon media driving on-Amazon outcomes. The Google search ad, the Instagram campaign, the email newsletter, the influencer link: what happens on Amazon after someone clicks them. That external-traffic question used to be a blind spot, because your ad platforms could see the click but not the Amazon purchase, and Amazon could see the purchase but not the ad.
It is not reporting for Amazon’s own ads. Sponsored Products, Sponsored Brands and the rest have their own reporting inside the console; Amazon Attribution exists specifically for the traffic you send from outside.
And it is free. The current status, per Amazon’s pages: the product is named simply Amazon Attribution, with beta label, accessed through the self-service Amazon Ads console (in the left-hand menu under Measurement and Reporting) or through integrated tool providers via the Amazon Ads API.
Amazon attribution supports marketing managers understand what drives Amazon sales outside of the Amazon ecosystem.
Eligibility and availability
Per Amazon’s product page, four groups can use it: professional sellers enrolled in Amazon Brand Registry, vendors, KDP authors publishing through Kindle Direct Publishing, and agencies with clients who sell products on Amazon.
The practical note for sellers: Brand Registry is the gate. A professional seller account alone is not enough, so if you are not enrolled, that is the prerequisite to sort first.
Geographically, availability spans North America (US, Canada, Mexico), Brazil, Europe (UK, Germany, France, Italy, Spain, Netherlands, Sweden, Turkey), the Middle East (Saudi Arabia, UAE) and Asia Pacific (Australia, India, Japan, Singapore).
If you sell in one of those markets and clear the eligibility bar, there is no pricing conversation to have. The only cost is the setup discipline described next.
How the tags work
Attribution tags are URL parameters generated per marketing strategy or ad group inside the console. You place them on the destination links of your off-Amazon ads: the Google search ad, the Instagram post, the email button. When someone clicks through, their subsequent on-Amazon activity, detail page views, add-to-carts, purchases and units sold, is associated with that tagged click. Amazon’s guide states the model plainly: a 14-day, last-touch attribution window, so a conversion must happen within 14 days of the click to be credited. Reporting also captures brand-halo effects on your non-promoted products, and new-to-brand purchases.
Two disciplines decide whether the data is useful.
First, tag granularity is analysis granularity. One tag covering all your Facebook activity tells you “Facebook works” and nothing else. A tag per campaign, or per ad group where decisions happen at that level, lets you compare the things you actually manage.
Second, never reuse tags across channels. A tag that appears in both an email and a search ad produces one blurred number that answers neither question. Distinct placement, distinct tag, always.
Set up this way, the console becomes the missing half of your external-traffic reporting: the ad platform shows the click cost, Amazon Attribution shows the Amazon outcome.
Reading the results
Amazon Attribution is click-based, last-touch measurement of tagged traffic. That sentence defines both its value and its boundary.
Influence without a click is invisible. Someone sees your TikTok video, says nothing, and searches Amazon for the product that evening: real influence, zero attribution, because no tagged click connects the two. It is a counter on your shop’s front door: everyone who walks through gets counted, but the people who heard about you on the street and came in through the marketplace entrance do not. So read the results as a floor on external media’s effect, not the total. Strong attributed numbers mean external media is working at least this well; modest ones do not prove it is failing.
Amazon introduced a “shopping-signal enhanced last-touch” attribution model, and some sellers assumed everything changed. It did not. That change concerns view-based attribution of ads serving inside the Amazon store, such as Sponsored Display viewable impressions. Amazon states click-based attribution is unchanged, and Amazon Attribution’s click-and-tag measurement is not affected. Do not conflate the two when reconciling reports.
Where it fits in a seller’s measurement stack
Amazon Attribution answers the external-traffic question tactically: which off-Amazon campaigns move Amazon outcomes, at the level of tags and placements. Weekly campaign decisions live here, and it does that job well for the price of zero. We have seen that advertisers experiment and compare results for a few weeks so they can compare Amazon attribution results with their own internal analytic solution.
The budget-level questions live elsewhere. How much should you spend off-Amazon at all? How does external media interact with your Amazon ads and your organic rank, when a surge of external traffic lifts a listing that then converts shoppers who never clicked anything? Those are mix questions, and click-level tools cannot see enough of the system to answer them. At MarSci we have developed a data-driven attribution model, one which goes above clicks and UTM parameters. Get access to our Causal-driven Attribution here.
Frequently Asked Questions
Amazon’s free measurement solution showing what off-Amazon marketing, search, social, display, video, email and influencer campaigns, drives inside Amazon: product detail page views, add-to-carts, purchases and sales. It works through attribution tags placed on ad destination links and lives in the Amazon Ads console under Measurement and Reporting.
Per Amazon’s product page: professional sellers enrolled in Amazon Brand Registry, vendors, KDP authors, and agencies with clients selling on Amazon. Availability spans North America, Brazil, Europe, the Middle East and Asia Pacific. For sellers the gate is Brand Registry: a professional account without enrollment does not qualify.
They are URL parameters generated per marketing strategy or ad group, placed on the destination links of your off-Amazon ads. When someone clicks through, their subsequent on-Amazon activity is associated with that tagged click under a 14-day last-touch model. Tag granularity equals analysis granularity, so tag each distinct placement separately and never reuse tags.
No. It is click-based, so influence without a tagged click is invisible: someone who sees your ad and later searches Amazon directly never appears in the numbers. Treat results as a floor on external media’s true effect, with aggregate methods like marketing mix modeling recovering the influence that arrives without a click.
