Marketing
Definition
Marketing attribution assigns credit for a conversion to one or more marketing touchpoints a prospect encountered. Models include: first-touch (all credit to first), last-touch (all credit to last), linear (equal credit across all), time-decay (more to recent), position-based (40-20-40 U-shape), and data-driven (ML-assigned).
Key points
- Single-touch models are simple but misleading for multi-touch journeys
- Multi-touch attribution better reflects how B2B sales really work
- Data-driven attribution (Google Analytics 4 default) uses ML when data volume supports it
- UTM parameters are the foundation — attribution fails without them
Example
A prospect reads a blog post (first touch), attends a webinar (middle), clicks a retargeting ad (last), and books a demo that closes. First-touch: 100% to blog. Linear: 33% each. U-shape: 40% blog, 20% webinar, 40% ad.
