A Referral Program is a marketing strategy that encourages existing customers to recommend a business's products or services to new customers. Typically, when a current customer refers someone who makes a purchase, both the referrer and the new customer receive rewards, such as discounts or cash bonuses. This approach helps businesses grow their customer base through word-of-mouth. These programs are beneficial for both parties. For businesses, they can lead to increased sales and customer loyalty. For customers, they provide an opportunity to earn rewards while sharing their positive experiences with friends and family. Many companies, including Amazon and Dropbox, successfully use referral programs to enhance their marketing efforts.
