4.9.6.4 - The "Coupon Site" Hijack: Affiliates ranking for "[Brand] Coupon" with fake codes just to set a cookie (Difficulty: Beginner | Ethics: Grey Hat | Path: Scale)

SECURITY BRIEFING: ATTRIBUTION THEFT MECHANICS. This lesson covers a prevalent "Grey Hat" tactic used by affiliate marketers to siphon budget from e-commerce brands without delivering incremental value. We are studying this mechanism not to deploy it, but to detect it, mitigate it, and protect your margins. The "Coupon Site Hijack" is technically a form of Last-Click Attribution Theft. It exploits the psychological friction at the checkout stage where a customer sees a "Discount Code" field and instinctively pauses their purchase to search for a code.

The mechanic is simple yet devastatingly effective. A customer, fully intent on purchasing, leaves your site to search Google for "[Your Brand] Discount Code." They find a generic aggregator site (e.g., "BestCoupons247" or a major player like RetailMeNot) ranking #1. These sites often list "Verified Codes" which are frequently fake, expired, or generic welcome offers. The site uses a "Click to Reveal" button. When the user clicks, an affiliate cookie is dropped on their browser. The user returns to your site, completes the purchase they were already making, and the coupon site claims the 10-15% commission.

Why is this critical? Because you are paying a Customer Acquisition Cost (CAC) for a customer you had already acquired. If that customer came from a Facebook ad (paid) or an Influencer (commissionable), the coupon site's "Last Click" cookie often overwrites the original source. You end up paying the coupon site for "closing" the sale, effectively stealing the credit from the channel that actually did the work. For a brand scaling to $1M+, this leakage can represent tens of thousands of dollars in wasted ad spend annually.
