| Trigger | Behavior |
|---|---|
| Reducing CAC | Referral program design |
| "referral", "레퍼럴" | Full program setup guide |
| Users already sharing organically | Amplify existing behavior |
| Type | Mechanism | Best For | Example |
|---|---|---|---|
| Double-sided | Both referrer and referee get reward | SaaS, marketplace | Dropbox, Airbnb |
| One-sided (referrer) | Only referrer gets reward | Low-friction products | Cash referral bonus |
| One-sided (referee) | Only new user gets benefit | Trial/freemium | "Get 1 month free" |
| Tiered | Rewards increase with more referrals | Power users | Ambassador programs |
| Milestone | Reward at specific referral counts | Viral products | "Invite 5 → unlock feature" |
# Referral Program: [Product Name]
## Incentive Structure
| Role | Reward | Trigger |
|------|--------|---------|
| Referrer | [e.g., 1 month free] | When referee [signs up / pays / activates] |
| Referee | [e.g., 20% off first month] | On signup via referral link |
## Sharing Mechanics
- **Unique referral link**: [user].product.com/ref/[code]
- **Share channels**: Copy link, Email, Twitter, WhatsApp
- **In-app placement**: Settings → "Invite Friends" + post-value moment
## Tracking
- Referral code in URL → cookie → attribution on signup
- Dashboard: referrals sent, signed up, converted, rewards earned
## Reward Fulfillment
- Automatic credit/discount application
- Email notification on successful referral
- Leaderboard for top referrers (optional)
## Anti-Fraud Rules
- Max [N] referrals per user per month
- Self-referral detection (same IP, email domain)
- Minimum activity threshold before reward unlock
Prerequisites (don't launch without these):
K = invites per user × conversion rate of invites
K > 1.0 → Viral growth (each user brings >1 new user)
K = 0.5 → Amplified growth (50% boost to other channels)
K = 0.1 → Minimal viral effect (optimize or rethink)
Example:
Average invites per user: 3
Invite conversion rate: 20%
K = 3 × 0.20 = 0.6 (good amplifier)
