Common Types

  • Cookie stuffing -- placing tracking cookies on users' browsers without consent to claim credit for future purchases
  • Attribution theft -- intercepting buyers mid-purchase to steal last-click credit from legitimate affiliates
  • Fake leads -- submitting invented or scraped contact information to collect per-lead commissions
  • Click spam -- generating massive volumes of fake clicks, hoping some coincidentally align with real conversions
  • Loyalty/coupon abuse -- injecting tracking cookies at checkout to hijack attribution from affiliates who actually drove the sale

Why It Matters

Unlike other forms of ad fraud where fake impressions and clicks are clearly illegitimate, affiliate fraud often involves real purchases by real customers. The fraud is in the attribution: fraudsters claim credit for sales they didn't actually influence. This makes detection significantly more complex than standard click fraud or impression fraud.

The damage extends beyond stolen commissions. Corrupted attribution data makes it impossible to identify which marketing channels actually work, legitimate affiliates lose motivation when fraud steals their credit, and sales teams waste resources following up on worthless fake leads.
