You work on the shop marketing team for a small hardware company with 10 franchise locations. Each franchisee has a budget that they want to use towards promoting their location and driving in-store traffic. What recommendation would you make?

Setting one campaign per location is the most effective approach because each franchise has its own budget and specific goals for driving in-store traffic to that particular store. This allows for tailored messaging, targeting, and promotions that are relevant to the local customer base and unique characteristics of each individual store. Setting one campaign per region, city, or country would dilute the impact, as it wouldn't account for the distinct needs and budgets of each individual franchise location, making it harder to optimize for in-store traffic at a granular level.
