Amazon Attribution Explained: How to Measure Off-Amazon Traffic

Amazon Attribution is a free tool that helps track how ads placed outside of Amazon convert into actions on the site, like page views, add-to-cart clicks, and actual purchases. This works through unique tags attached to your ad links, which can be set up manually or in bulk for certain campaigns. Only brand-registered sellers, vendors, Kindle Direct Publishing authors, and agencies associated with their accounts can use it. Plus, using this tool qualifies you for the Brand Referral Bonus, giving you a nice 10% discount on the usual referral fees from those sales.

TL;DR

What is Amazon Attribution?

Amazon Attribution is a free tool that shows the effect of ads outside Amazon once users click them on sites like Google or Facebook. Standard tracking services, such as Google Analytics, stop following users when they leave the ad platform and head to Amazon. However, Attribution jumps back in to see what goes down after that.

This feature lets brands find out stuff that regular analytics miss. For example, which Facebook campaigns really boost sales on Amazon? Did an influencer’s post lead to purchases or was it just for show? Are non-brand Google keywords worth paying for since they eventually end up at Amazon anyway? Without Amazon Attribution, businesses would have to estimate the answers using rough guesses or indirect measures.

How Amazon Attribution works

Attribution adds unique tags to your off-Amazon ad links. When a shopper clicks one and buys anything on Amazon within two weeks, the system connects that purchase to the ad. It’s easy too,  just make a campaign in Attribution, grab the tags for your different ads, and stick those special URLs wherever you want. Data then comes right back to your dashboard, all inside 24 to 48 hours.

For reporting, Attribution credits the last click within that 14-day window by default. So if someone clicks a Facebook ad and then a Sponsored Products ad before buying, the Sponsored Products click gets the credit. Amazon has since rolled out Conversion Path Reporting and a Multi-Touch Attribution beta that surface multi-touch journeys separately, but the standard Attribution dashboards you'll work in day-to-day still use last-click.

Who can use Amazon Attribution?

Attribution is open to four user groups, but only inside supported marketplaces.

•         Brand-registered sellers. Seller Central users enrolled in Amazon Brand Registry with brand representative status. The tool appears under Measurement and Reporting once eligibility is confirmed.

•         Vendors. Vendor Central accounts get Attribution access without a separate Brand Registry step; the vendor relationship already establishes brand ownership.

•         KDP authors. Kindle Direct Publishing authors can use Attribution to track off-Amazon traffic to their book pages.

•         Agencies. Agencies cannot get direct access on their own; they must be linked to an eligible seller or vendor account through user permissions in Ad Console.

Supported marketplaces now span 23 countries: the United States, Canada, Mexico, Brazil, the UK, Germany, France, Italy, Spain, the Netherlands, Belgium, Poland, Ireland, Sweden, Turkey, Saudi Arabia, UAE, Egypt, South Africa, Australia, India, Japan, and Singapore. Newer additions like Amazon.ie (launched March 2025) and expanded Amazon Ads support across Poland, Belgium, Sweden, Egypt, and South Africa have closed most of the previous coverage gaps. Sellers outside these countries can still use Attribution if they sell into one of the supported marketplaces. Sellers outside these countries can still use Attribution if they sell into one of the supported marketplaces.

Channels you can measure with Amazon Attribution

Attribution supports paid search, social, video, email, and influencer traffic. The granularity you build at tag creation is the granularity you get at reporting, so plan tag structure before you start.

The two highest-leverage channels for most brands are Google Search (non-brand keywords funneling to Amazon) and Meta prospecting (cold audiences discovering the brand). Influencer and YouTube tracking is where Attribution proves its worth most clearly, since those channels are otherwise nearly impossible to measure with confidence.

What metrics Amazon Attribution tracks

Attribution reports the full funnel from off-Amazon click to on-Amazon purchase.

The metric most teams underuse is Detail Page Views. Click-through rates can lie (bots, accidental taps), but a shopper who actually lands on your product page is qualified traffic. If clicks are high and detail page views are low, you have a redirect or tracking issue, not a conversion issue.

Setting up tracking: Manual Creation vs Bulk Upload

Tracking tags for Amazon Attribution can be set up in two ways.

•         Manual Creation. Used for traffic sources outside of Google and Facebook, or for marketing campaigns that require less granular reporting. Best for TikTok, YouTube, email, influencer partnerships, and any channel where you only need a handful of tags.

•         Bulk Upload. Used for Google and Facebook (and Instagram) campaigns. Bulk Uploads deliver granular keyword-level or ad-level data and let you create up to 100,000 Google search keyword tags or 8,500 Facebook or Instagram ad tags in a single file.

Pick Manual for low-volume, exploratory channels. Pick Bulk Upload when you need creative-level or keyword-level performance data on Google or Meta. Below are the step-by-step instructions for each method.

Manual Creation: step-by-step

1.       Sign in to advertising.amazon.com and open the left menu. Go to Measurement and Reporting, then select Amazon Attribution.

2.       In the campaign manager, click Create campaign.

3.       On the New Campaign page, under Creation Method, choose Create manually.

4.       Enter a campaign name that reflects the channel and objective (e.g. "Meta_Q4_Prospecting_UGC"). Select the products (ASINs) you want to measure.

5.       Create an ad group for each creative, audience, placement, or partner you want to track separately. Granularity at this stage is what makes the reporting useful later.

6.       For each ad group, specify the publisher (e.g. Facebook, TikTok, YouTube, Email), channel type (social, video, email, etc.), and click-through URL (your Amazon product detail page, Store, or search URL).

7.       Click Create. Attribution generates a unique tag for each ad group. Copy the tags individually or download them as a CSV file.

8.       Paste the tagged URL into the destination URL field of your off-Amazon ad inside the relevant ad manager (Meta Ads Manager, TikTok Ads Manager, your email tool, or the influencer's link placement).

9.       Wait 24 to 48 hours for data to populate. Validate by comparing click counts in Attribution against click counts in the source platform.

Bulk Upload: step-by-step (Google and Facebook only)

1.       Sign in to advertising.amazon.com and navigate to Measurement and Reporting, then Amazon Attribution.

2.       In the campaign manager, click Create campaign.

3.       On the New Campaign page, under Creation Method, choose Upload a file to create in bulk.

4.       In the Bulk Upload Settings section, select your publisher: Google Ads or Facebook/Instagram.

5.       Download the bulk file template (Excel). Open the Instructions tab and follow the steps for the publisher you selected.

6.       Generate the source data. For Google Search campaigns: open Google Ads Report Editor, go to Reports > Custom > Table, select the required columns, download the report. For Meta campaigns: export the required ad-level data from Meta Ads Manager.

7.       Fill in the template. For Google, complete columns A through H on the Keywords tab. For Meta, complete columns A through J on the Ads tab.

8.       Back in Amazon Attribution, click Upload File and submit the completed bulk template.

9.       Once processed, click Add Products to associate the ASINs you are tracking with the bulk-created tags.

10.   Download the resulting Attribution Tags file. For Google: upload the Final URL Suffixes back into Google Ads (Keywords > More > Upload). For Meta: use Export & Import > Import Ads in Ads Manager to apply the tags.

11.   Wait 24 to 48 hours for data to populate. Validate by comparing click counts between Amazon Attribution and the source platform.

Amazon Attribution vs UTM tracking

UTM tags (read by Google Analytics) and Attribution tags do different jobs. UTMs tell you which ad sent the traffic; Attribution tells you what that traffic did once it reached Amazon. Most brands need both.

Run them in parallel: UTMs on your destination URL track the off-Amazon ad performance, Attribution tracks the on-Amazon conversion. Tools like atom11 stitch Attribution data alongside Sponsored Ads performance so the off-Amazon and on-Amazon halves of the funnel sit in one view.

The halo effect: how off-Amazon traffic boosts on-Amazon rank

Amazon's algorithm rewards listings that pull in qualified external traffic. Brands running consistent Attribution-tagged campaigns see compounding benefits beyond the direct attributed sales:

•         Higher organic rank. External purchases signal high demand, and Amazon often boosts keyword rankings for listings receiving steady off-Amazon traffic.

•         Better conversion rate. Off-Amazon visitors are typically warmer and more purchase-ready than cold marketplace browsers, lifting overall listing CVR.

•         Best Seller Rank lift. Sales velocity from external traffic feeds directly into BSR, which then drives more organic visibility on Amazon.

•         Lower blended CAC. The Brand Referral Bonus credits ~10% of attributed sales back, offsetting a meaningful slice of your off-Amazon ad spend.

The Brand Referral Bonus

Attribution unlocks the Brand Referral Bonus program, which credits roughly 10% of attributed sales back to your account as a reduction on referral fees. The exact percentage depends on the product category.

Any Amazon sale that comes through an Attribution-tagged off-Amazon click is flagged as eligible. Amazon credits the bonus to your account approximately two months after the sale. For brands spending heavily on Meta or Google to drive Amazon traffic, the bonus often covers a meaningful slice of the ad cost itself, which makes Attribution a no-brainer to set up.

Best practices for using Amazon Attribution

•         Tag at the ad-group level, not the campaign level. Channel-level data is useful; creative-level and audience-level data is actionable. Granularity now saves rebuilds later.

•         Use consistent naming. Adopt a convention like channel_objective_audience_creative. Make sure ad platform names match Attribution names exactly to avoid reporting chaos.

•         Compare Purchase Rate, not just Sales. A channel with low total sales but high purchase rate often scales better than a high-volume channel with weak conversion.

•         Treat the 14-day window as a floor. Brands with longer consideration cycles will under-report; treat Attribution numbers as a conservative baseline for high-AOV products.

•         Stack with Sponsored Ads data. Off-Amazon traffic lifts on-Amazon organic and Sponsored Ads performance. Reading Attribution in isolation misses the halo: an off-Amazon Meta campaign often lifts the ROAS of the Sponsored Products campaign defending the same ASIN, but neither dashboard shows the other's impact.

•         Refresh tags quarterly. Update tag naming and structure each quarter to match new campaigns and audiences. Stale tag taxonomies break dashboards within 90 days.

Limitations to know

Attribution is powerful but not unlimited. Knowing where it stops short prevents bad calls from incomplete data:

•         No customer-level data or email addresses (Amazon keeps that locked down).

•         No lifetime value or repeat purchase tracking.

•         Reporting lag of 24 to 48 hours (not real-time).

•         Cross-device journeys outside the 14-day window are not captured.

•         Click-only attribution for off-Amazon tags. View-through conversions exist on Amazon's side, but they're never applied to Attribution-tagged external campaigns

•         Single-touch (last-click) is the default model for Attribution reports. Conversion Path Reporting and Multi-Touch Attribution surface multi-touch paths separately but don't change the default crediting in Attribution dashboards

Brands that get the most out of Amazon Attribution treat it as the missing half of their off-Amazon analytics stack rather than a standalone dashboard. UTMs and Meta Ads Manager tell you what happened off Amazon; Attribution tells you what happened next. Together they finally answer the question every brand director keeps asking: which dollar of off-Amazon spend actually produced an Amazon sale.

Conclusion

Amazon Attribution bridges that off-Amazon measurement gap for brands using Google, Meta, or influencer traffic. Set it up with bulk uploads for Google and Facebook, and add manual tags for the rest. Be sure to tag things granularly from the start. The Brand Referral Bonus even covers the setup costs in the first quarter itself.
