A purchase or enquiry may follow search, advertising and email interactions. The path contains measured touchpoints, not necessarily every interaction the customer experienced.
GA4 Attribution paths reports key events, purchase revenue, days to key events and touchpoints. Distinguish the report date range, selected key events and attribution lookback settings. A universal 14-day or 30-day path window is not an accurate description.
Use recurring paths to decide which channel combinations deserve investigation. Frequency and attributed credit alone do not prove a channel caused the result.
