Every model is wrong, some are useful. First-touch over-credits awareness, last-touch over-credits the closer, multi-touch spreads credit but hides behind assumptions. The goal is not truth, it is a consistent rule everyone trusts.
The model matters less than measuring it in one place that reconciles to revenue, see attribution your CFO will sign off.
No model captures how buying really happens, across channels, over months, with offline conversations you never see. First-touch and last-touch each tell a convenient half-truth. Multi-touch sounds rigorous but buries assumptions.
So stop hunting for the true model. Pick one, apply it consistently, measure it in a warehouse that reconciles to booked revenue and use it to compare periods, not to declare a single channel the winner.
First-touch for demand creation, last-touch for capture. Different questions, different models.
Consistency beats accuracy. Switching models to flatter a channel fools only you.
Platform reports each over-credit themselves. A warehouse de-duplicates the truth.
If attributed pipeline does not add up to booked revenue, the model is fiction.
The rule that decides how credit for a conversion is split across the marketing touchpoints that led to it.
First-touch, last-touch and multi-touch. They credit the first, the last or a split across all touchpoints.
None is correct. Match the model to the question, apply it consistently and measure it where it reconciles to revenue.
Because buying spans many channels over months, including offline conversations you never see, so no model captures it fully.
