Referral marketing is a structured program that incentivizes existing customers to recommend a business to people they know, typically rewarding both the referrer and the new customer when a referral converts. It's built on trust — the underlying engine of word-of-mouth — and it pays only for proven results rather than impressions or clicks.
That matters more each year: paid acquisition costs on Meta and Google have climbed 40% to 60% per conversion since 2023, while referral acquisition costs stay comparatively flat. Reward structures fall into three categories, and the gap between them shows up directly in participation.
- Ask at peak satisfaction
- Post-purchase, on confirmation and receipts, not an arbitrary date.
- Both sides rewarded
- Double-sided removes the awkwardness of a one-sided ask.
- Sized to margin
- $10–20, or 15–25% of AOV; above $50 rarely moves volume.
- Fraud as a threshold
- Managed with purchase minimums, not eliminated out of fear.
