Marketing Attribution Explained Without the Jargon
Marketing attribution is the method used to assign credit for a conversion across the touchpoints that happened before it. Different models answer different questions, so there is no single attribution model that is automatically “correct” for every business.
Key takeaways
- Last-click favors the final touchpoint.
- First-click favors the discovery source.
- Multi-touch models distribute credit across multiple interactions.
- Compare models instead of treating one model as unquestionable truth.
Why attribution exists
A customer may discover you through an ad, return through search, click an email, and finally buy after another ad. Attribution gives you a consistent rule for interpreting that sequence.
Common attribution models
First-click
All credit goes to the first known touchpoint. Useful for understanding discovery.
Last-click
All credit goes to the final known touchpoint before conversion. Useful for understanding closers, but it can undervalue earlier influence.
Linear and other multi-touch approaches
Credit is distributed across more than one touchpoint. These models can better reflect longer journeys but also require more complete data and stronger assumptions.
Practical rule
Pick the model that matches the decision you are making, and check whether your conclusion changes under another reasonable model.
