This document discusses understanding shopper behavior to drive growth. It identifies three fundamental shopper roles: stock-up shoppers who visit the whole store for large baskets, top-up shoppers who visit most of the store for medium/small baskets, and emergency shoppers who visit parts of the store for small "must have" items. Understanding which shopper missions apply to specific categories and channels is important. Placement tactics can capitalize on high traffic areas and take advantage of different shopper missions.
