Marketing Attribution Models Explained

Updated August 30, 2026 · Independent editorial guide

An attribution model is a rule—or model—that allocates conversion credit. Simple models assign 100% of credit to one touchpoint. Multi-touch models distribute credit across several interactions.

Single-touch models

First click rewards acquisition. Last click rewards the final measurable interaction. Both are easy to interpret but compress a complex journey into one event.

Multi-touch models

Linear models split credit evenly; time-decay gives more weight to later touches; position-based models emphasize selected stages. Vendor-specific models may also blend first-party, modeled or survey data.

Where software fits

Attribution software helps collect the underlying events, connect touchpoints and apply these models consistently across channels. If native platform reports are materially affecting budget decisions and routinely conflict with backend revenue, a dedicated measurement layer may be worth evaluating.
