Conversion tracking for marketplace sellers, and what is genuinely impossible
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. That is not a limitation of your setup or a gap a better tool fills. What is available is real but narrower, and knowing the difference will save you from buying something that cannot work.

Marketplaces · what breaks
What marketplace sellers usually run into
- 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.
Marketplaces · the fix
What changes — 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.
Marketplaces · architecture
The conversion map for marketplace sellers
Five things, only some of which are measurable, and the page says which.
- 1
Off-marketplace ad click
Measurable on your side. It stops being traceable the moment it reaches the listing.
- 2
Listing view
Available in aggregate through the marketplace's own analytics, not per visitor.
- 3
Order placed
The marketplace records it. No click identifier attached, ever.
- 4
Attribution program reporting
Aggregate and delayed where the marketplace offers it. Directional, not reconcilable.
- 5
Promo code redemption
The one clean per-order signal you can create yourself.
Marketplaces · diagnose
Where marketplace sellers tracking usually breaks
- 01
No click identifier on the order
The structural fact underneath everything else on this page.
- 02
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.
- 03
Customer data the marketplace will not release
Which also limits what remarketing and matching are possible.
- 04
Vendors promising otherwise
If a proposal describes per-order click attribution on Amazon, ask exactly which identifier travels and where it is stored.

FAQ
Marketplaces questions, answered
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.
Same shape. The marketplace owns the checkout and the customer, and per-order click attribution is not available. The specifics of each platform's own reporting differ and are worth learning; the structural limit is identical.
