No, incentives are not a necessity for customer referral marketing. Though incentives can be a powerful motivator, so can fantastic customer experience. Many customers will be motivated enough to refer your business simply because they enjoyed the product and interacting with your business. That being said, if you don’t offer incentives, it is important to send out referral requests and include mentions of your customer referral marketing program throughout your customer communications. And remember, regardless of whether or not you add an incentive, always thank your customers for referring your business!
