Footfall walks in and walks out, unmeasured
You know how many transactions you closed. Do you know how many people you didn't convert - and why they left empty-handed? Most retailers still can't answer that. They're optimizing the 20% of the story that shows up on the till receipt and ignoring the other 80% that walked the floor. Dwell time is the tell: shoppers who linger 90+ seconds in a zone are roughly 4x more likely to buy than those who don't, and a 1% lift in dwell time has been linked to a 1.3% lift in apparel sales. If you're not measuring dwell by zone, you're leaving that signal on the table.
