Customer Satisfaction Is Worthless, Customer Loyalty Is Priceless: How to Make Customers Love You, Keep Them Coming Back, and Tell Everyone They Know by Jeffrey Gitomer is a book that challenges the traditional notion of customer satisfaction and highlights the importance of building customer loyalty. Gitomer argues that customer satisfaction alone is not enough to create long-term success for businesses; instead, organisations should strive to cultivate customer loyalty, which leads to repeat business, positive word-of-mouth, and sustainable growth.
