Key Questions To Ask Your Retail Media Partners
Most retail media pitches lead with reach and placements. The questions that actually separate a good partner from a mediocre one are about measurement, data and fees, and most media plans never get around to asking them.
Retail media pitches are built to lead with reach numbers and placement inventory, because that’s the easy, flattering part of the conversation. The questions that actually determine whether the spend performs sit further down the deck, if they’re addressed at all.
Start with measurement, not media rates
A retail media partner’s rate card tells you what you’ll pay. It tells you nothing about whether the sales the platform reports back to you would have happened anyway. That’s the single most consequential question in any retail media negotiation, and it’s also the one most partners would rather not lead with, because a platform reporting its own attributed sales has every incentive to claim credit generously.
This isn’t a hypothetical concern specific to any one platform. It’s structural: whoever owns the measurement also owns the incentive to make that measurement look favourable, in exactly the same way a media owner marking its own homework has always tempted a favourable read. Retail media is newer than that dynamic, but not exempt from it.
The questions that actually separate partners
| Area | The actual question | Why it matters |
|---|---|---|
| Measurement methodology | Is reported sales lift measured through incrementality testing, or just correlated exposure and purchase? | Correlation-only reporting overstates impact, sometimes significantly, and there’s no way to know by how much without asking directly. |
| Data usage | What happens to our first-party data if we share it, and can we audit that? | “We don’t sell your data” and “your data never trains our broader ad products” are different commitments, and the difference matters. |
| Inventory transparency | Can we see exactly where our ads served, at a placement level, not just an aggregate report? | Aggregate-only reporting can hide low-quality placements inside an otherwise decent-looking average. |
| Fees and minimums | What’s the full fee structure, including anything not itemised on the media rate card? | Platform, data, and management fees layered on top of media cost can meaningfully change the real CPM. |
| Incrementality proof | Will you run or support a holdout test to validate the reported lift? | A partner confident in their numbers has no reason to resist a holdout. Reluctance here is itself informative. |

Red flags in how a partner answers these
The answer matters less than how directly it’s given. A partner who takes a measurement methodology question and redirects to reach and impression numbers is telling you something, even if they never say it outright. Same with a fee question answered only in terms of the headline CPM, or a holdout test request met with “our reporting is already validated internally,” without naming the methodology used to validate it. None of these individually disqualifies a partner. Two or three together, on the same pitch, are worth treating as a real signal rather than an oversight.
Where this fits in a broader retail media strategy
These questions matter most before a contract is signed, when leverage is highest, not after spend has already started and switching costs have set in. Building them into a standard partner evaluation template, asked identically of every platform under consideration, also makes it possible to compare answers side by side rather than relying on memory of how confidently each pitch was delivered.
The broader context worth keeping in view: retail media budgets are growing fast enough that most businesses evaluating a partner today are doing it for the first or second time, without the years of hard-won pattern recognition that exists for more mature channels like search or programmatic display. That inexperience is exactly what a template of standard questions is meant to compensate for, so the evaluation doesn’t depend entirely on how persuasive any single pitch happened to be.

Will a retail media partner actually agree to a holdout test?
Established, confident partners often will, sometimes as a standard part of onboarding. Reluctance is more common from platforms whose reported lift numbers wouldn’t hold up well under a genuine incrementality comparison.
How many of these questions should be asked before signing?
All of them, ideally in writing, as part of the evaluation rather than as informal conversation. A written answer is one a partner is more likely to stand behind later if the relationship doesn’t perform as pitched.
Is it reasonable to ask these questions of an established, well-known retail media platform?
Yes. Platform size and reputation aren’t a substitute for measurement transparency, and established platforms with confident methodology generally have no issue answering these questions directly.
