B2B attribution simulator · v2 · 2026-05
Same revenue. Same ad spend. Six different ROAS values.
For B2B with multi-touch sales cycles, your reported ROAS depends entirely on which attribution model you pick. Drag the sliders below to watch how the same conversion gets carved up differently across six standard models.

What each model does
Last-click
100% of credit to the final touch. If paid isn’t the last touch, paid gets zero — the dominant structural bias in B2B reporting.
First-click
100% of credit to the first touch. Inverse bias of last-click. Useful for top-funnel attribution but hides bottom-funnel effort.
Linear
Equal credit per touchpoint (1/N). Treats every touch as equally responsible. Simple but blind to recency and position.
U-shaped
40% to first, 40% to last, 20% spread across middle. Useful when the intro and close moments are clearly the most influential.
Time-decay
Credit decays exponentially with days since touch (7-day half-life — Google’s default). Heavily favors touches near the conversion event.
Data-driven
Approximates Google’s data-driven model: linear baseline with mid-funnel boost. Real DDA requires significant conversion volume per path.
