❓ Frequently Asked Questions
What is a good ROI for a referral program?
A good referral program ROI is 100%+ (earning $2+ for every $1 spent). Top performers achieve 300-500% ROI. Since referred customers have 25% higher lifetime value and referral CAC is 50-70% lower than paid ads, referral programs typically outperform other acquisition channels.
What is viral coefficient (K-factor) and why does it matter?
Viral coefficient measures how many new customers each existing customer brings through referrals. A K-factor above 1.0 means viral growth - each customer brings more than one new customer, creating exponential, self-sustaining growth. This is the holy grail of referral marketing.
How do customer reviews improve referral programs?
Customers who leave reviews are 3-4x more likely to refer others because they're already engaged advocates. Their referrals also convert 30% better because review-writers tend to refer higher-quality leads who trust their recommendations. The moment after leaving a positive review is optimal for requesting referrals.
Should I use single-sided or double-sided rewards?
Double-sided rewards (rewarding both referrer and friend) generate 2.3x more referrals than single-sided programs. They remove the guilt from referring and make the offer more attractive to friends. While slightly more expensive, the increased participation more than compensates through better ROI.
What's a realistic referral rate for my business?
Average referral rates are 2-5% of your customer base. Top-performing programs achieve 10-20%. Referral rates depend heavily on customer satisfaction, program visibility, and reward value. Double-sided programs and leveraging happy review-writers can significantly boost participation.
How long until a referral program becomes profitable?
Payback periods typically range from 2-6 months. Well-designed programs with strong customer satisfaction can break even within 1-2 months. The key is balancing reward costs against customer lifetime value while optimizing referral and conversion rates.
What conversion rate should I expect from referrals?
Referral conversion rates typically range from 10-18% for B2C and 10-15% for B2B. These are significantly higher than cold traffic (1-3%) because referred customers come with built-in trust. Conversion rates improve by 30%+ when referrers have left positive reviews.
How much should I reward for referrals?
Reward value should be 10-30% of customer lifetime value or average order value. Sweet spot: Give both parties 10-20% of AOV. For a $100 AOV, consider $10-20 for the advocate and $10-20 for the friend. Test different values to find your optimal balance of participation and profitability.
