Amazon Attribution: How to Measure External Traffic to Your Listings

Amazon Attribution is a free Amazon Ads measurement tool that shows what shoppers do on Amazon after clicking a link from outside Amazon, such as a Google ad, a Meta or TikTok post, an influencer, or your email list. You create a tagged link for each channel, use it in your marketing, and Amazon reports detail page views, add-to-carts and purchases that came from it.

Who can use it

Amazon Attribution is available to brand-registered sellers and to vendors in supported marketplaces, as well as agencies working on their behalf. It is accessed through the Amazon Ads console (Measurement and reporting) or through integrations with some third-party tools. Availability and features differ by marketplace, so check the console for your region.

What it measures

• Clicks on your tagged link.
• Detail page views on Amazon that followed.
• Add-to-cart events.
• Purchases and product sales attributed to the click within its attribution window (typically 14 days).
• Purchases of other products from your brand, not only the one you linked to.

It does not measure what happened on the external platform beyond the click. Impressions, reach and cost on Google or Meta still come from those platforms. You combine the two to calculate return.

How to set it up

1. In the Amazon Ads console, open Measurement and reporting and choose Amazon Attribution. Accept terms if prompted.
2. Create an order (Attribution's name for a group of tags) and select the products you are promoting.
3. Choose how to create tags: manually for a single link, or via the integrations for supported ad platforms like Google Ads and Meta, which can generate tags for campaigns automatically.
4. Name each tag by channel, campaign and creative, for example 'meta_prospecting_video1'. Clear names make reports readable.
5. Copy the tagged URL and use it as the destination in your ad, post, email or influencer brief.
6. Wait for data. Reports update over the following days as clicks and conversions are recorded.

The Brand Referral Bonus

Brand-registered sellers enrolled in Amazon's Brand Referral Bonus program can earn a credit on sales driven by their external marketing that Attribution measures. Amazon describes the bonus as averaging around 10% of the product sales generated, varying by category, applied as a credit against referral fees. You must enroll in the program in Seller Central and use Attribution tags for the traffic. Check the program page for current terms, eligible marketplaces and exclusions before building it into your math.

How to calculate return on external traffic

Combine Attribution sales with the external platform's cost.

The numbers here are illustrative. If you earn the Brand Referral Bonus, add it back as a reduction in cost: at a 10% bonus, the Google row recovers about $336, lowering effective spend to $864 and the ACoS-equivalent to about 26%. Compare each channel against your break-even ACoS, the same yardstick you use for Amazon ads.

Why external traffic can matter for Amazon PPC

Sales from external traffic count toward a product's overall sales history on Amazon. Amazon does not publish how its organic ranking works, but sales velocity is widely understood to play a role, so external traffic that converts can support organic rank and, indirectly, make your Sponsored Products ads more efficient. That effect is real for some brands and negligible for others. Watch total sales and TACoS before and after a campaign rather than assuming. See how PPC affects organic rank for the same logic applied to on-Amazon ads.

Reading the Attribution report

Attribution reports can be viewed by order, tag, publisher and product. Start at the publisher level (Google, Meta, email and so on) to see which channels drive purchases at all, then drill into tags to compare campaigns and creatives within a channel. The product view shows which ASINs shoppers actually bought, which is often not the one you linked to. If a channel sends traffic to one product but most purchases are of a different item, consider linking directly to the item people buy or to a store page that features both.

Tips for cleaner Attribution data

• Use one tag per channel and creative so you can tell what works.
• Send traffic to the right page. A product detail page usually converts better than a store page for a single product; a store page can suit a multi-product brand campaign.
• Expect lower conversion than on-Amazon search. Social traffic is often earlier in the buying process than a shopper searching on Amazon.
• Compare apples to apples. Attribution uses its own window; Sponsored Products seller reports use a 7-day window. See the attribution window guide.
• Do not double count. A shopper who clicks your Meta ad and later your Sponsored Products ad may be credited in both reports.

A simple test plan for a new channel

1. Pick one product with solid reviews and a listing that already converts well on Amazon. Cold external traffic is less forgiving than Amazon search.
2. Set a fixed test budget and duration, for example $1,000 over four weeks, and decide in advance what result would justify continuing (such as an ACoS-equivalent under your break-even after any Brand Referral Bonus).
3. Create separate Attribution tags for each audience and creative so you can see which combination works.
4. Record total sales, organic rank on two or three main keywords and TACoS for the two weeks before the test as a baseline.
5. At the end, compare attributed sales against spend, and also check whether total sales and rank moved beyond what Attribution credited.
6. Keep, adjust or stop the channel based on the rule you set in step 2, not on how the campaign feels.

Expect the first test to be noisy. External platforms need time to optimize delivery, and small budgets produce small samples. Treat a single four-week test as a first read, not a final verdict.

Common problems

• No data: check the tag is in the final destination URL and not stripped by a link shortener or redirect.
• Clicks but no detail page views: the link may land on the wrong page or a mobile app handoff may be failing; test it on a phone.
• Detail page views but low purchases: the external audience may be poorly matched, or the listing may not convert cold traffic. See Amazon PPC conversion rate for listing fixes that also help here.
