Amazon Ads conversion tracking for marketplace sellers
This page exists to say something most vendors will not: if your sales happen on Amazon, Etsy or Walmart, the marketplace owns the customer, the checkout and the data, and the per-order click attribution this site builds for other platforms is not available to you. What Amazon Ads adds on top of that is a mechanical requirement: the Amazon click identifier, where one exists have to reach the record that holds the money, because Amazon Ads can only credit a conversion it can tie back to a click it recognizes. This page covers both halves — what a conversion is in marketplace sellers, and what Amazon Ads specifically needs to accept it.

Amazon Ads for sellers: Amazon measures the sale, you reconcile it
For Sponsored Products, Sponsored Brands and Sponsored Display, Amazon records the attributed order itself, with no click identifier, pixel or upload from the seller. Marketplace sellers should read attributed sales and new-to-brand metrics in the Amazon Ads console, reconcile them against Seller Central or Vendor Central totals, and build tracking only for DSP campaigns sent to their own store.
This is the one platform here where marketplace sales are measured, because the ad platform and the store belong to the same company. The catch is that you get Amazon's view: attributed sales by campaign and keyword, under Amazon's own windows, which have differed between seller and vendor accounts and between ad types. Check which window each report uses before comparing ACoS across them.
Attributed sales are not incremental sales. Sponsored Products on your own brand keywords frequently claim orders that would have arrived organically, so a low ACoS on brand terms says little about what the spend achieved. New-to-brand metrics, where available, and Amazon Marketing Cloud, if your account has access, are the tools for separating keeping a customer from winning one.
Reconcile attributed sales against your business reports over a closed month, and watch the other-SKU or halo sales, meaning orders for a different product of yours after an ad click. They count in attributed sales and can make a campaign look better than its advertised product deserves. For Etsy or Walmart, Amazon Ads plays no part; Walmart Connect is the equivalent inside Walmart.
Amazon Ads · Marketplaces · what breaks
Why Amazon Ads under-reports for marketplace sellers
- 01
The marketplace owns the checkout and the customer
You get an order report, not a click-to-order join. No tool changes this.
- 02
Off-marketplace ads that cannot be attributed per order
You can drive traffic to a listing and you cannot see which click produced which sale.
- 03
Vendors selling per-order attribution that does not exist
The most common thing sold into this category, and it does not work the way it is described.
- 04
The Amazon click identifier, where one exists never reaches the record
This is the important thing and most guidance skips it: Amazon Ads spans two very different situations. Sponsored ad formats driving to an Amazon listing produce conversions Amazon measures itself, with no click identifier passed to you and no per-order join available. Amazon DSP driving to your own site is a different case, where a click identifier can reach your landing page and be captured like any other network's.

What working looks like — Amazon Ads · Marketplaces
A clear statement of what can and cannot be measured
Before you spend anything, so the decision is informed.
The marketplace's own tools used properly
Attribution programs, brand analytics and promo-code tracking each do something real within their limits.
Your own channels measured properly
If you also sell direct, that side is fully measurable and is usually where the attention should go.

How Amazon Ads and marketplace sellers actually connect
- 1
The conversion in marketplace sellers
The conversion map here is mostly a map of what is missing. The marketplace records the order and shares an aggregate; there is no identifier that travels from your ad to that order, so the events below are the honest maximum.
- 2
Amazon Ads needs a click to match
For off-Amazon conversions: an event, a timestamp, a value and the click identifier. For on-Amazon conversions: nothing, because the measurement is not yours to do.
- 3
The identifier: the Amazon click identifier, where one exists
This is the important thing and most guidance skips it: Amazon Ads spans two very different situations. Sponsored ad formats driving to an Amazon listing produce conversions Amazon measures itself, with no click identifier passed to you and no per-order join available. Amazon DSP driving to your own site is a different case, where a click identifier can reach your landing page and be captured like any other network's.
- 4
Where it gets sent from
The marketplace's own order and settlement reports, with their aggregation level understood before anything is compared.
- 5
Deduplication and window
For on-Amazon purchases the question does not apply, because you are not measuring the conversion at all — Amazon is. For traffic to your own site the usual shared-identifier pattern applies. Amazon's attribution windows differ by ad product and by whether the conversion happens on Amazon or on your site. Establish which product and which destination you are reporting on before comparing any figure.

The conversion map for marketplace sellers
Five things, only some of which are measurable, and the page says which.
| Event | What it means here |
|---|---|
| Off-marketplace ad click | Measurable on your side. It stops being traceable the moment it reaches the listing. |
| Listing view | Available in aggregate through the marketplace's own analytics, not per visitor. |
| Order placed | The marketplace records it. No click identifier attached, ever. |
| Attribution program reporting | Aggregate and delayed where the marketplace offers it. Directional, not reconcilable. |
| Promo code redemption | The one clean per-order signal you can create yourself. |

The structural fact underneath everything else on this page.

Aggregate reporting treated as measured conversions
Marketplace attribution programs report at a level that cannot be reconciled per order, and trying to will waste weeks.

Customer data the marketplace will not release
Which also limits what remarketing and matching are possible.

Read Amazon's own attribution reporting for on-Amazon sales, and your normal reconciliation for off-Amazon conversions
The structural limit is worth stating plainly to anyone selling you on this: for sales that complete inside Amazon, per-order click attribution does not exist and cannot be built. Amazon Attribution gives aggregated, delayed reporting. Anyone offering per-order joins on Amazon-completed sales is describing something that is not available.

Amazon Ads · Marketplaces · when not to buy
When you don't need this — Amazon Ads · Marketplaces
- If Amazon Ads already reports conversions that reconcile against the marketplace's own order and settlement reports within a few percent, this is working and there is nothing to buy.
- Measure identifier coverage yourself first — pull your last hundred records and count how many carry the Amazon click identifier, where one exists.
- If all your Amazon Ads spend drives to Amazon listings, there is no conversion tracking build here — only a reporting exercise inside Amazon's own tools, and it is worth knowing that before commissioning anything.

FAQ
Amazon Ads · Marketplaces questions, answered
No. Amazon attributes Sponsored Products orders itself and shows them in the advertising console, so there is nothing to install or upload.
Different scope and timing: attributed sales include other-SKU orders and follow the ad's attribution window, while Seller Central counts every order by date. Compare over a closed month and expect a gap.
No, and neither can anyone else. Amazon does not attach a click identifier from your off-site ad to the resulting order, and it does not release the customer data that would allow a match. Amazon's own attribution program gives aggregate, delayed reporting — genuinely useful, and not the per-order join this site builds for Shopify or WooCommerce. Anyone quoting you for the latter is describing something that does not exist.
Three things. Use the marketplace's own attribution and analytics tools properly, since most sellers do not. Use unique promo codes or channel-specific landing paths where you need a clean per-order signal. And if you also sell direct, put the real measurement effort there — that side is fully attributable and usually under-invested.
The data is a reason, not the reason. A direct channel gives you the customer relationship, better margins and full attribution together. If you are weighing it, the measurement gain is real and it should not be the whole argument.
