How do you measure ads if people walk in without clicking?

If they walk in without tapping, they are asked as they sit where they saw you and it is noted. The campaign is not measured only by clicks if the venue lives on people who pass and come in. Leave a box on the order: ad, walk-in, someone they know. The report says few clicks and the room is full of people who saw the poster on the phone and did not tap. The week’s sheet with those answers beside the spend, not instead of it.
