Attribution assumptions
Make the methodology explicit for finance stakeholders.
Default attribution counts customers whose first recorded touch was organic search. Assisted customers can be blended with a weighting factor.
Where to find inputs
- GA4: Acquisition reports → First user source/medium.
- CRM: First-touch channel field on closed-won customers.
- Assisted conversions: Multi-channel funnel assists.
Tip: Keep customer counts aligned with the same period as costs. That keeps CFO comparisons clean.
