Okay, so I would say that, first of all, adjust your referral program rewards to your customer’s purchasing behavior. So if you’re selling a product that your customers can buy on a somewhat regular basis, or if you’re selling a subscription, even more, make sure that your rewards are adjusted accordingly. And so they can, for example, get either a free subscription or a discount on a future purchase. That way, you’re not only incentivizing them to refer their friends and acquire new customers but you’re also retaining those existing customers that you currently have because you’re giving them a discount to come back to your store.
