We developed a two-stage modeling approach that separated short-term sales drivers from long-term brand equity growth. Discounts were shown to generate stronger lifts online than offline, but they also weakened brand equity over time. Media channels were measured for their specific contributions across platforms and campaign types. Store count and store grouping effects were analyzed to identify where incremental growth was most likely. The results gave the client clear visibility into which tactics generated immediate impact and which fueled sustainable brand strength.
