Process Flow
Animated overview of the full workflow
TL;DR
GA4 has two acquisition reports that look similar but measure different things. User Acquisition shows how new users first found your site (their very first visit). Traffic Acquisition shows how all sessions (including returning visits) arrived. Use User Acquisition to understand which channels bring new customers. Use Traffic Acquisition to understand which channels drive ongoing engagement and conversions.
