referral-program

Start by identifying trigger moments when customers are most likely to refer, then choose a share mechanism such as in-product links or referral codes. Size the incentive using the formula: (Customer LTV × Gross Margin) minus Target CAC, and prefer double-sided rewards for higher conversion.

Referral programs reward existing customers for recommending to their network and work best for products with natural word-of-mouth. Affiliate programs pay ongoing commissions to partners like bloggers and creators, suiting higher-ticket products that justify revenue sharing.

Multiply the average number of invitations each user sends by the invitation conversion rate. A K-factor above 1 means viral exponential growth, while below 1 means referrals amplify but do not replace other acquisition channels.

Referral platforms include ReferralCandy, GrowSurf, Friendbuy, and Viral Loops. For affiliates, options include PartnerStack, Rewardful, FirstPromoter, and Tapfiliate. Choose based on payment integration, fraud detection, and payout management.

Combine technical measures like email verification, device fingerprinting, and delayed reward payouts with policy rules such as referral caps and reward clawbacks. Requiring referred users to complete a meaningful action before payout deters most abuse.

Low conversion usually stems from a weak landing experience for referred users or insufficient incentive for the new user. Test stronger double-sided rewards, make the referrer's endorsement visible, and shorten the referred user's path to value.
