Marketing Attribution Models Explained
Attribution models are rules for distributing credit. No single model is universally correct; each highlights a different part of the buying journey.
First-click
Credits the first known touchpoint. Useful for studying discovery. In practice, document your assumptions and compare the reported number with the business outcome you can verify. Measurement is most useful when the team understands what the data includes, what it misses and which decision the metric is meant to support.
Last-click
Credits the last known touchpoint before conversion. Simple and action-oriented, but can undervalue earlier demand creation. In practice, document your assumptions and compare the reported number with the business outcome you can verify. Measurement is most useful when the team understands what the data includes, what it misses and which decision the metric is meant to support.
Linear
Splits credit evenly across known touches. In practice, document your assumptions and compare the reported number with the business outcome you can verify. Measurement is most useful when the team understands what the data includes, what it misses and which decision the metric is meant to support.
Position-based
Gives extra weight to first and last touches while sharing the rest. In practice, document your assumptions and compare the reported number with the business outcome you can verify. Measurement is most useful when the team understands what the data includes, what it misses and which decision the metric is meant to support.
Data-driven
Uses modeled patterns to assign credit, which can be useful but less transparent. In practice, document your assumptions and compare the reported number with the business outcome you can verify. Measurement is most useful when the team understands what the data includes, what it misses and which decision the metric is meant to support.
Best practice
Compare models and keep the underlying business outcome stable. In practice, document your assumptions and compare the reported number with the business outcome you can verify. Measurement is most useful when the team understands what the data includes, what it misses and which decision the metric is meant to support.
What to do next
Choose the next guide based on the decision you are trying to make. If your main problem is collection quality, start with server-side tracking. If the data exists but channels disagree, study attribution models. If you are evaluating software, compare implementation, integrations and decision value—not marketing claims alone.
