Footfall Definition by IPSOS

We define Footfall, also known as People Counting or Shopper Counting, as the measurement of the number of people entering a shop or shopping mall.

By counting how many people enter your shop, your footfall means we can determine other key metrics which are crucial for survival in today’s retail climate – such as Conversion Rates and ATV (Average Value Transaction).
