How Coupon Affiliate Works
Coupon affiliates — sites like RetailMeNot, Honey, Rakuten (cashback), and thousands of niche deal blogs — attract consumers who are already ready to purchase and searching for a discount code before checkout. When a shopper searches "[brand] coupon code" and clicks through a coupon affiliate's link, the affiliate receives commission even though the sale would likely have occurred without their involvement. This "last-click hijacking" is the central controversy of coupon affiliate management. Studies suggest 40-60% of coupon affiliate commissions represent non-incremental sales on orders that would have converted without affiliate intervention.
Why Coupon Affiliate Matters for B2B Marketing
Despite incrementality concerns, coupon affiliates serve legitimate functions: they reduce cart abandonment (shoppers who find a code complete checkout rather than abandoning), they capture deal-motivated buyer segments who require a discount to convert, and they provide high-volume commission data that helps validate tracking infrastructure.
Coupon Affiliate: Best Practices & Strategic Application
Manage coupon affiliates strategically rather than excluding them entirely. Issue unique, trackable coupon codes to each affiliate to measure incrementality. Set coupon values low enough (5-10% off) to attract deal-seekers without cannibalizing full-price sales. Block coupon affiliates from bidding on branded search terms in your affiliate agreement.
Agency Perspective: Coupon Affiliate in Practice
The Honey browser extension (owned by PayPal) is a particular concern for brands. Honey can override your affiliate links at checkout with its own, redirecting commission from your legitimate content affiliates to Honey. Monitor this via regular mystery shopper audits and work with your network's fraud team to implement Honey-blocking if incrementality analysis shows material commission theft.
