What Is Marketing Attribution?
Marketing attribution is the practice of assigning credit for a conversion or revenue to the marketing touchpoints that influenced it. The attribution model you choose decides how credit is split across channels and interactions, so you can see which marketing actually drives pipeline and revenue.
Key takeaways
- Attribution connects marketing touchpoints to revenue outcomes.
- The model you choose changes which channels look effective — pick one deliberately.
- No model is perfect; match it to your sales-cycle length and number of touches.
Common attribution models
| Model | How it assigns credit |
|---|---|
| First-touch | 100% to the first interaction |
| Last-touch | 100% to the final interaction before conversion |
| Linear | Evenly across every touchpoint |
| U-shaped | 40% first, 40% lead-creation, 20% spread between |
| W-shaped | Weights first touch, lead creation and opportunity creation |
| Time-decay | More credit to touches closer to the conversion |
Single-touch vs multi-touch
Single-touch models (first- or last-touch) are simple but blunt — they ignore everything in between. Multi-touch models spread credit across the journey, which is more realistic for long B2B cycles but needs clean tracking to be trustworthy.
Frequently asked questions
What is the best marketing attribution model?
There's no single best model. Short, few-touch journeys are served fine by last-touch; long multi-stakeholder B2B cycles call for a multi-touch model like W-shaped. Choose for your sales motion, then stay consistent.
What's the difference between first-touch and last-touch attribution?
First-touch credits the interaction that first introduced the contact; last-touch credits the final interaction before they converted. They answer different questions — discovery vs closing.
What is multi-touch attribution?
Multi-touch attribution distributes credit across several touchpoints in the journey rather than just one, giving a fuller picture of what influenced the deal.
