SMG “The Advertising Effectiveness of In-Store Retail Media”, 2025
How grocery retailers turn in-store media into measurable value
Convert footfall into advertising yield
Screens at shelves, fridges, and checkouts let you turn shopper traffic into booked impressions. You stay in control of placements and brand fit, while opening a complementary revenue stream beyond trade margins. With programmatic access, inventory can be filled efficiently and scaled across locations.
Make first-party insights work harder
Your loyalty and transaction data reveal real buying patterns. Combine those insights with in-store placements to build audiences that truly reflect shopper intent. The effect: more relevant campaigns, better outcomes for brands, and measurable value for your retail-media business.
Speak in the shopping moment
Point-of-decision communication wins. Promote launches, highlight seasonal ranges, or trigger price incentives exactly when and where they matter. Use contextual signals — time of day, weather, or store format — to adapt messaging dynamically and keep it useful for shoppers.
Run and scale everything from one platform
Plan, sell, deliver, and measure your in-store media with a unified toolset. SSP1 connects you to demand, DMP1 powers targeting, and NMS1 keeps your network under control — from creative checks to reporting. Fewer hand-offs, faster execution, clearer results.
