What is Attribution Modeling
Determining channel contribution to conversion
Attribution Modeling
Attribution Modeling — methodology for determining the contribution of each marketing channel and touchpoint to the final customer conversion.
Main Attribution Models
| Model | Distribution | Features | |-------|--------------|----------| | Last Click | 100% to last | Simple but inaccurate | | First Click | 100% to first | Awareness evaluation | | Linear | Evenly distributed | All touches equal | | Time Decay | More closer to conversion | Time consideration | | Position-Based | 40/20/40 | First + last | | Data-Driven | ML model | Most accurate |
Traditional Attribution Problems
- Cross-device tracking — one user, different devices
- Offline touchpoints — calls, office visits
- Brand influence — not directly measurable
- Assisted conversions — upper funnel undervalued
Modern Approaches
- Multi-Touch Attribution (MTA) — multiple touches
- Marketing Mix Modeling (MMM) — econometrics
- Unified Measurement — MTA + MMM
- Incrementality Testing — channel A/B tests
Tools
- Google Analytics 4 (data-driven)
- Adobe Analytics
- Segment / Amplitude
- Custom ML models
Effectiveness Metrics
- ROAS by channel
- CAC by entry point
- Assisted conversions
- Path length
