iHeart AdBuilder will select the stations and times-of-day to play your audio ad where your primary customers are most likely to listen. By excluding certain times-of-day or days-of-the-week, you may accidentally limit your exposure to your primary customers. AdBuilder takes care of this by optimizing your campaign to play at the right times and on the right stations.
