Self-referral happens when an affiliate converts through their own tracking link, earning commission on their own purchase, registration or deposit, or on accounts belonging to family members or identities they control. Many programs prohibit it, because the brand pays an acquisition fee for a customer that no partner actually referred.
How it works
The simple case is an affiliate buying through their own link to collect commission as a personal discount. The more damaging version is creating many accounts to collect CPAs or sign-up bonuses: the same person registers repeatedly with different emails, usually from the same device, IP range or payment method. In iGaming, fintech and crypto, where CPAs are high, self-referral overlaps with bonus abuse and multi-accounting.
Example
Example: a crypto app pays a $50 CPA, and new users get a $20 welcome bonus. An affiliate opens 30 accounts with disposable emails, makes the minimum qualifying deposit on each and collects $1,500 in commission plus $600 in bonuses. Fraud checks later show that 26 of the accounts share two device fingerprints and one withdrawal wallet.
How to detect and prevent it
- Match conversion data (device fingerprint, IP, payment method, name, address) against the affiliate's own account details.
- Flag clusters of conversions from the same device or IP shortly after clicks from that affiliate.
- Use a qualification baseline and a hold period, so commissions are approved only after real activity.
- Define self-referral in the affiliate agreement, including whether personal purchases are allowed at all, and reverse commissions when it is proven.
Some retail programs may allow affiliates to earn on personal purchases; what matters is that the rule is written down and applied consistently. Detection patterns are covered in affiliate fraud detection.
