Count traffic in multiple windows
Observe the location at morning, lunch, after-work, evening, and weekend periods. One busy window does not prove the site can support the business throughout the week.
Measure useful traffic
Not all traffic is valuable. Useful traffic matches the business occasion and can notice, access, and enter the storefront with little friction.
Compare anchors and access
Nearby offices, apartments, schools, transit, parking, and retail anchors help explain why people pass the site. Access constraints can reduce the value of raw traffic.
