Microsoft 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 Microsoft Ads adds on top of that is a mechanical requirement: msclkid has to reach the record that holds the money, because Microsoft 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 Microsoft specifically needs to accept it.

Microsoft Ads to Amazon listings: no UET on the order page
Microsoft Ads cannot record a conversion for an Amazon, Etsy or Walmart order, because UET cannot run on marketplace pages and msclkid never reaches the order. Marketplace sellers should tag Microsoft campaigns with Amazon Attribution for aggregate sales, bid manually, and set up real conversion goals only for their own store's checkout.
Many sellers import their Google campaigns into Microsoft and end up running the same Amazon-bound Search ads on Bing, often with conversion goals copied across that will never fire. Remove or pause goals that cannot record anything, so nobody switches on automated bidding against an empty signal and reads the result as a channel failure.
Microsoft's search audience skews older and desktop-heavy, which suits some marketplace categories: replacement parts, office and home supplies, and hobby gear bought by people who search with a model number. Those buyers often go to Amazon to compare prices and buy anyway, so the Bing click is research. Expect Amazon Attribution to credit only part of that, and check Brand Analytics for search terms that rise with Microsoft spend.
Microsoft Shopping campaigns need a Merchant Center store tied to a domain you control, so they only make sense for the direct-store side of the business. There, a normal build applies: UET firing on the order confirmation, msclkid stored with the order, and the purchase goal counting every conversion so a repeat buyer is a second sale.
Microsoft · Marketplaces · what breaks
Why Microsoft 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
Msclkid never reaches the record
Microsoft's click identifier, appended when auto-tagging is enabled. It depends on the UET tag being present on the site — without UET, msclkid arrives in the URL and there's nothing consuming it, which is a common half-configured state on accounts imported from Google.
Microsoft · Marketplaces · the fix
What working looks like — Microsoft · 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 Microsoft 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
Microsoft Ads needs a click to match
msclkid inside the import window, a conversion goal name matching one in the account, a timestamp and a value.
- 3
The identifier: msclkid
Microsoft's click identifier, appended when auto-tagging is enabled. It depends on the UET tag being present on the site — without UET, msclkid arrives in the URL and there's nothing consuming it, which is a common half-configured state on accounts imported from Google.
- 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
The same counting question applies: one conversion per click for lead-type goals, every conversion for ecommerce. Accounts imported from Google frequently carry over the goal structure and not the counting review, so it's worth reading every goal rather than assuming the import got it right. Check Microsoft's current offline import window and attribution settings directly. They resemble Google's closely enough to be assumed and differ enough to matter.

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 the upload's match rate and Microsoft's conversion goal diagnostics
Almost every Microsoft account we open was imported from Google Ads, and the import copies campaign structure without copying the tracking. The result is a live account spending money with UET missing, msclkid unconsumed, or conversion goals pointing at pages that don't exist on the site any more.

Source of truth
The marketplace's own order and settlement reports, with their aggregation level understood before anything is compared
- A plain statement of what is and is not attributable, before any work is commissioned.
- Promo-code redemptions reconciled per order where that mechanism is used.
- Direct-store revenue measured fully and reported separately from marketplace revenue.
- No number presented as measured when it came from an aggregate model.
- The upload's match rate and Microsoft's conversion goal diagnostics read directly, not inferred from an upload succeeding.

Microsoft · Marketplaces · when not to buy
When you don't need this — Microsoft · Marketplaces
- If Microsoft 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 msclkid.
- If your Microsoft account is a straight import you've never separately configured, fix the account structure and UET installation first — offline import on top of an unconfigured account produces data nobody will trust.

What gets built — Microsoft · Marketplaces
Marketplace attribution tools configured where they exist
Amazon's attribution program and equivalent tools give aggregate rather than per-order insight. Useful, and not the same thing.
Unique promo codes or landing paths per channel
The practical way to separate channels without a click join.
Your direct-to-consumer store measured fully
Where a real per-order build is possible and worth doing.
Nothing claimed that the data cannot support
The reporting states its own limits.
Dispatch via Microsoft's offline conversion import
Uploaded against msclkid, closely mirroring Google's approach. Because so many Microsoft accounts are imported wholesale from Google Ads, people assume full parity — verify the current column format and requirements in Microsoft's documentation rather than reusing your Google template unchanged.

FAQ
Microsoft · Marketplaces questions, answered
Yes, by adding the Amazon Attribution tag to the ad's final URL. Amazon reports aggregate sales by tag and sends nothing back to Microsoft.
Sometimes, on specific search terms with buying intent and little competition. Without a conversion signal, keep it small and manually bid, and judge it on Amazon's attribution report over a full month.
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.
