Last-click attribution in affiliate marketing over-rewards coupon sites and under-rewards content creators who drive genuine awareness. Better attribution models reveal which partners truly earn their commission.
The Last-Click Problem
A customer discovers your product through a review blog (affiliate A), researches on a comparison site (affiliate B), then searches for a coupon code at checkout (affiliate C). Last-click gives 100% credit to the coupon site - the least valuable touchpoint.
Multi-Touch Affiliate Attribution
Implement multi-touch attribution that credits each affiliate in the conversion path. Use position-based (40/20/40), linear, or time-decay models. This reveals which partners introduce customers versus which merely intercept them. See track conversions across channels.
Coupon and Promo Code Attribution
Assign unique promo codes to each affiliate for last-touch tracking without cookies. Combine with UTM parameters for full-path visibility. This method works reliably in cookieless environments.
Affiliate Incrementality
The key question: would these sales have happened without the affiliate? Test incrementality by pausing specific affiliates and measuring sales impact. Compare attributed sales to incremental sales to find your true cost per incremental acquisition.
