In the Band 3 Optimization, we’re concerned about the Interface, the moment of truth when people who have Awareness, Interest, and Desire generated in Bands 1 and 2 are ready to take Action. If we are successful at Optimizing the Interface, people take Action and become Customers, entering Band 4 of the model.
At HSN, we looked at customer communication this way: as soon as a customer makes their first purchase, they begin the defection (dis-Engagement) process. I’ve referred to this idea before as “customers naturally fall down through the bands“. The approach assumes every customer interaction we have after the first purchase directly affects how long this new customer will remain a customer.
