Definition
Traffic means the number of customers who entered a store. It's also referred to as visitor count, or simply Traffic.
Traffic is the number of people who enter a store out of everyone who passes by it — so converting more passersby into visitors is a key initiative. The indicator for how well you do that is Capture Rate.
Passersby — the number of customers who pass by the store
Capture Rate — the percentage of passersby who go on to enter the store
A wide range of measurement tools exist — from manual counters to the latest traffic-counting sensors and AI-powered cameras. Traffic measurement also feeds several other important store KPIs, including Conversion, customer-to-staff ratio, and visitor counts by floor.

Why it matters
When you think about what Traffic affects, Sales is probably the first thing that comes to mind. Start by looking at what Sales is made of:
Sales = Average Purchase × Transactions
Transactions itself breaks down further: Transactions = Traffic × Conversion.
To hit a big target like Sales, you need concrete, specific initiatives — which is why breaking a metric down into its components like this, then targeting each one, matters. Traffic is closely tied to Transactions (a component of Sales) together with Conversion — the share of visitors who go on to make a purchase.
Traffic is now easy to measure accurately with modern systems. As consumer behavior keeps shifting, keeping track of this core KPI helps you understand customer behavior — and acting on that analysis is one of the most direct paths to hitting your sales targets.
