Marketing attribution determines which touchpoints and channels deserve credit for conversions. Proper attribution helps allocate budget to what actually works.
Attribution Models
View Attribution Models
Last Click: 100% credit to final touchpoint (most common, flawed)
First Click: 100% credit to first touchpoint
Linear: Equal credit to all touchpoints
Time Decay: More credit to recent touchpoints
Position-Based: 40% first, 40% last, 20% middle
Data-Driven: AI determines credit based on patterns

Practical Advice
No attribution model is perfect. Use multiple views, understand each model's bias, and combine with incrementality testing for better decisions.
