Connects online ad exposure to offline in‐store visits. This is an increasingly popular measurement option for brick-and-mortar retailers and quick-serve-restaurants (QSRs) whose ultimate goal is to drive consumers into their storefronts. Foot traffic attribution measures incremental sales lift by comparing the number of individuals who were both exposed to a digital ad and entered a brick-and-mortar location to those who entered the store but were not served a branded ad. Metrics that can be measured include total store visits, cost per store visit, store visit lift, cost per store visit lift, and incremental revenue.
