Retail media is the new programmatic. Same margin, new name.

Retail media networks are the fastest-growing line in many consumer budgets and the least governed. The lessons from a decade of programmatic apply directly.

If you sell through large retailers, their media networks are now a significant and growing line in your marketing budget, often funded out of trade spend and managed by a different team from the one running your brand media. It is measured by the retailer, planned inside the retailer's platform, and priced by the retailer. You are, in effect, buying media from your own customer.

We have seen this movie before. It was called programmatic, and it took the better part of a decade for advertisers to get real transparency, independent measurement, and pricing they could actually benchmark. Retail media is running the same curve, just earlier in it, with the added complication that the seller is also the channel you depend on for distribution.

The same problems, showing up earlier

Measurement controlled by the seller is the first issue, and the most consequential. Retail media networks report on their own effectiveness, using their own attribution logic, inside their own walled garden. That is a structural conflict of interest, not a character flaw in any particular retailer. A network that credits itself for sales that would have happened anyway has no incentive to fix that on its own.

Pricing with no external benchmark is the second. Because retail media inventory doesn't trade in an open market the way programmatic display eventually did, there is no easy way to know whether a given placement is priced fairly relative to another network, or relative to what the same reach would cost through a different channel entirely.

Inventory quality varies enormously between placements that carry the same rate card price. A sponsored product slot at the top of a high-intent search result is not the same asset as a banner on a category page nobody scrolls to, but both often get sold and reported on as though they were interchangeable.

And there's a layer of intermediaries between the brand and the retailer, the ad tech powering the retailer's own platform, agencies with incentives that don't always match the client's, all taking a cut before the money reaches actual shelf placement or actual media.

What to do now, while it's still early

Bring retail media into the same governance as the rest of the media budget, with one owner accountable across brand and trade rather than two teams working from different numbers. That alone fixes more than most companies expect, because right now the trade team and the brand media team are frequently optimizing against different goals with no shared view of total spend.

Push for independent incrementality testing, even when the retailer resists it, and treat resistance itself as information. A network confident in its own numbers should welcome a third-party check. One that isn't is telling you something.

Build a price benchmark across networks so you have a basis for comparison the retailer can't supply you. And put contracts in place, with the retailer and with the technology partner sitting between you, that specify data access and audit rights up front, before the relationship calcifies into "this is just how it's done."

Two questions worth putting to your own team this quarter: who owns retail media spend end to end, and can they tell you, with a straight face, what a dollar spent there actually returns compared with a dollar spent anywhere else in the plan?

Be honest, too, about the strategic trade sitting underneath all of this. Some retail media spend is really the cost of shelf position and retailer favor, dressed up as advertising. That might be a perfectly rational decision to make. It should be made as a decision, with eyes open, not accepted by default because the invoice showed up bundled with everything else the retailer bills you for.

Advertisers who apply what they already learned the hard way from programmatic will get to fair terms in a couple of years instead of a decade. The ones who keep treating retail media as a trade-marketing relationship, outside the normal discipline applied to every other channel, will end up paying for that lesson twice.

One practical test: pull the last quarter's retail media invoices and check whether anyone outside the trade team has ever seen them. If the answer is no, that's not a data problem. It's a governance problem wearing a data problem's clothes, and it's the easiest one on this list to fix once someone actually owns it.
