Multi-Touch Attribution Models
Understanding Attribution Models
Most customers see multiple ads before purchasing. Multi-touch attribution distributes credit across all touchpoints.
Last-Click Attribution (Default)
100% credit to the last ad clicked before purchase
Example: Clicked Ad A, then Ad B, then purchased → Ad B gets 100% credit
First-Click Attribution
100% credit to the first ad that introduced the customer
Example: Clicked Ad A, then Ad B, then purchased → Ad A gets 100% credit
Linear Attribution
Equal credit to all touchpoints
Example: Clicked Ad A, then Ad B, then purchased → Each gets 50% credit
Time-Decay Attribution
More credit to recent touchpoints
Example: Ad A gets 30%, Ad B (more recent) gets 70%
