Albertsons Media Collective launched an incrementality measurement capability that quantifies whether in-store campaigns actually drive purchase behavior beyond baseline traffic, according to Albertsons Companies. The tool separates shoppers exposed to in-store media from a matched control group, then measures the sales difference attributable to the campaign itself.

The framework works by creating holdout stores or shopper cohorts that never see the campaign, then comparing purchase rates between exposed and unexposed groups across the same products and time windows. Albertsons runs this analysis across its loyalty data, which covers millions of identified shopping trips, allowing the retailer to track individual basket changes rather than relying on store-level sales aggregates. Brands using the service receive reports showing incremental units sold, incremental revenue, and return on ad spend isolated from seasonal trends or existing purchase intent.

This works because retail media has historically struggled to separate correlation from causation. A brand runs an endcap display during a holiday week, sees sales spike, and credits the display without knowing how many shoppers would have bought the product anyway. Incrementality measurement removes that ambiguity by directly measuring the counterfactual: what happened in stores or to shoppers who never saw the media. The control group provides the baseline, and the difference is the true lift.

For brands selling through grocery, this closes the attribution gap that has plagued physical retail for decades. Digital platforms like Meta and Google have long offered lift studies that compare exposed and unexposed users, but in-store media has lacked the shopper-level identity layer required to run the same test. Albertsons holds that identity layer through its loyalty program, which ties individual transactions to specific customer IDs. That gives the retailer the infrastructure to run true A/B tests inside physical stores, matching the rigor of digital incrementality frameworks.

The steal for a smaller physical-product brand is to negotiate incrementality windows with any retailer that offers loyalty-linked reporting. If you are launching a promotional display at a regional chain, ask the buyer whether their loyalty program can generate a matched control report: same demographic profile, same purchase history, different store set. Many mid-tier grocers already run this analysis internally to evaluate their own promotional calendar. Request the same data cut for your campaign, even if you pay a modest analytics fee. If the retailer cannot provide it, run your own version by selecting test and control store pairs with similar demographics and baseline velocity, then comparing weekly sales between the two groups during and after the campaign. Track absolute unit lift, not just percentage growth, and calculate cost per incremental unit sold by dividing your total media spend by the net new units attributable to the campaign.

For brands spending five figures or more on in-store media, incrementality measurement shifts the conversation from vanity metrics to profit contribution. A display that generates $50,000 in total sales might look successful, but if $45,000 of that would have occurred without the display, the true incremental revenue is only $5,000. If the display cost $8,000 to produce and place, the campaign destroyed value. Incrementality measurement surfaces that math before you scale the program across additional doors.
