An attribution approach that distributes conversion credit across multiple affiliate touchpoints in a customer's purchase journey, rather than awarding all credit to the last click (last-click attribution) or the first click (first-click attribution). Multi-touch attribution models are more accurate representations of how affiliate content contributes to purchase decisions, but they are more complex to implement and may conflict with single-publisher attribution models. Why multi-touch matters: a typical purchase journey for a considered product may involve: Day 1: customer reads a review article from Publisher A (first-touch); Day 7: customer clicks a comparison guide from Publisher B (mid-touch); Day 15: customer uses Publisher C's coupon code to complete purchase (last-touch). Under last-click attribution, Publisher C gets all commission credit. Under first-click attribution, Publisher A gets all credit. Neither model reflects the actual contribution of all three publishers. Common multi-touch models: linear attribution: equal credit distributed across all affiliate touchpoints in the journey; time-decay attribution: more credit to touchpoints closer to the conversion; U-shaped attribution: 40% to first touch, 40% to last touch, 20% distributed across middle touches. Practical implementation challenges: most affiliate networks operate on single-touch (typically last-click) attribution; implementing true multi-touch attribution requires custom tracking infrastructure that captures all affiliate touchpoints in a customer journey and a commission splitting mechanism; few programs do this at scale. Practical approaches for brands without full multi-touch infrastructure: analyze which publisher types appear in first-touch vs. last-touch positions across your attributed conversions; use this analysis to adjust commission rates or tiers to reflect the differential value of discovery vs. closing touchpoints; pay content publishers who frequently appear as first-touch at rates that reflect their journey-starting value, even within a last-click attribution system.
