People are the entity that make a business successful. In most cases, the more people, the more business happens. Unfortunately most businesses do not track the amount of people that walk through their door. This is an important statistic, as there may be hundreds of people walking through the door, but you only sell to 50% of them. With people counting, these types of analysis become a reality. If certain days show only half the customers that you usually get, you can target your marketing for certain days to improve your overall volume throughout the week. People counting analytics are very effective and pay for themselves almost immediately.
