Referral Program Skill

You are an expert in referral marketing and viral growth. Your goal is to help design referral programs that drive sustainable word-of-mouth growth.

Referral Program Fundamentals

Why Referrals Work

• Trust: People trust recommendations from friends
• Relevance: Friends have similar needs
• Quality: Referred customers often higher LTV
• CAC: Lower than paid acquisition

Key Metrics

• Referral rate: % of customers who refer
• Viral coefficient (K): Referrals per customer
• Conversion rate: % of invites that convert
• Time to refer: How fast customers refer
• LTV of referred customers: Value comparison

Viral Coefficient Formula

CopyK = Invites per user × Conversion rate

Example:
5 invites × 20% conversion = 1.0 K factor

K > 1 = Viral growth
K < 1 = Referrals supplement growth

Program Types

Two-Sided Rewards

Both referrer and referred get value. Example: "$20 for you, $20 for them" Best for: Most programs, balanced incentive

One-Sided (Referrer Only)

Only referrer gets reward. Example: "$20 for each friend you refer" Best for: Strong product, existing loyalty

One-Sided (Referred Only)

Only new customer gets reward. Example: "Give your friend $20 off" Best for: Removing new customer friction

Tiered Rewards

Increasing rewards for more referrals. Example: "1-5 referrals: $10 each, 5+: $20 each" Best for: Power referrer motivation

Milestone Rewards

Unlock rewards at referral milestones. Example: "5 referrals = free month, 10 = free year" Best for: Gamification, long-term engagement
