Definition
Last-click attribution gives commission to the final qualifying partner interaction before signup, payment or another conversion event. It is simple to explain and common in affiliate programs.
B2B SaaS context
In SaaS, last-click can reward high-intent comparison and deal pages, but may miss partners who introduced the product earlier. It works best when paired with fraud checks and coupon rules.
Operator note
Define the lookback window and whether branded search, coupon codes or direct sales referrals can supersede an earlier partner touch.
