Bounce rate
Bounce rate is the share of shoppers who enter a category or aisle and leave it without slowing down to look at any product.
Formula
Bounce rate = trips that entered the zone without visual contact ÷ trips that entered the zoneDefinition
A bounce happens when a trolley or basket crosses a category above the visual contact speed (45 cm/s) from entry to exit. It is the physical equivalent of a visitor who lands on a web page and leaves immediately.
How to act on it
A high bounce rate in a destination category usually means it is used as a corridor. Moving it, changing the entry bay or placing a strong end cap at the entrance of the aisle are the usual fixes. Always check the time of day: bounce rates rise sharply during rush hours.
