The Scale of the Problem
Ad fraud cost the global advertising industry an estimated $84 billion in 2023. In affiliate and performance marketing specifically, fraud manifests in uniquely damaging ways: you're paying not just for exposure, but for fake results.
Understanding fraud types and prevention strategies isn't optional if you want to run profitable campaigns at scale.
8 Common Types of Affiliate Marketing Fraud
1. Click Fraud
Bots or low-wage click farms artificially inflate click counts, exhausting budgets and skewing attribution data. Estimated to affect 25–30% of all paid search clicks globally.
2. Cookie Stuffing
Fraudulent affiliates drop affiliate tracking cookies on users' browsers without any genuine referral, then claim commission when those users later purchase.
3. Domain Spoofing
Fake publishers claim their traffic comes from premium brand-safe domains when it actually originates from low-quality or harmful sites.
4. Lead Fraud
Submissions filled with fake or stolen personal information, auto-filled by bots or manually by fraud rings. These leads can appear valid briefly before bouncing during verification.
5. Call Fraud
In pay-per-call, fraudsters use duration stuffing (calling and staying on hold to meet billing thresholds), IVR bypass bots, and overseas call farms generating fake customer calls programmatically.
6. Incentivized Traffic
Users are paid small amounts to click links, download apps, or call numbers. They have zero genuine intent but generate real billing events.
7. Brand Bidding
Affiliates bid on your trademarked brand keywords in paid search — capturing traffic that would have converted organically — then claim affiliate commission.
8. Conversion Pixel Manipulation
Technical manipulation of the conversion tracking pixel or postback URL to fire conversion signals without genuine customer actions occurring.
