Fornell and Wernerfet used the term "defensive marketing" to describe attempts to reduce customer turnover and increase customer loyalty. This customer-retention approach was contrasted with "offensive marketing" which involved obtaining new customers and increasing customers' purchase frequency. Defensive marketing focused on reducing or managing the dissatisfaction of your customers, while offensive marketing focused on "liberating" dissatisfied customers from your competition and generating new customers. There are two components to defensive marketing: increasing customer satisfaction and increasing switching barriers.
