Attribution Modeling Comparison
Last-click undervalues top-funnel. Linear over-credits low-value. Data-driven (algorithmic) most accurate.
Model comparison
Example customer journey: Display → SEO → Email → Search → Purchase
| Model | Display | SEO | Email | Search |
|---|
| Last-click | 0% | 0% | 0% | 100% |
| First-click | 100% | 0% | 0% | 0% |
| Linear | 25% | 25% | 25% | 25% |
| Time-decay | 10% | 15% | 25% | 50% |
| Position-based | 40% | 10% | 10% | 40% |
| Data-driven | 5% | 30% | 20% | 45% |
Choosing your model
- Last-click — simple, but undervalues awareness
- First-click — credits brand-builders
- Linear — balanced view
- Time-decay — recency-weighted (most common)
- Position-based — emphasizes first + last
- Data-driven — algorithmic (Google's default in GA4)
Multi-touch reality
Average customer journey: 5-12 touchpoints. Channels rarely act alone. Use multi-touch attribution to value channels correctly.
For CardPrepAI: data-driven if GA4 has 100+ conversions; time-decay otherwise.
