Let’s imagine, for example, that you’re selling a soft drink. The category typically has two types of buyers: passionate and infrequent. Either you drink soft drinks every day and twice on Sunday, or you have them occasionally when eating lunch. The former kind of customer is of serious interest to the marketer, who will want to reward their loyalty. The latter type, not so much. Those consumers merely need to be reminded of the product and prompted at the right moments to buy, such as when they’re in an amusement park on a hot day.
