Why this matters · Retail media
The path customers walk is the rate card brands want to buy.
Flow data maps the actual routes shoppers take through your store — which aisles get the eyeballs, which endcaps get the dwell, which displays get walked past versus stopped at. That's the data brands need to price retail media inventory, pick the right slots for new product launches, and validate impressions for ad partners. Operationally it still drives store layout, staffing, and curbside capacity — but the same data layer becomes a retail media rate card.
