We keep record of every person who inquires about a storage space. When the customer calls we always ask how they heard about us. Also, when the customer rents we have them fill out a form that requires they put how they heard about us.

At the end of each month we create a report showing how many inquires we got from each source and how many we converted per source and overall.

We know how much we are spending per source so we can track our cost per inquiry and cost per rental.
