Behavior Flow

Behavior flow is a view that follows users' movement step by step: from the entry page or event, to the next step, through to the exit point.

Behavior flow answers what happens next, and unlike a funnel — where you predefine the path — it discovers users' real, open-ended routes. Its strength is seeing unexpected branches and loops; its weakness is that when routes are highly varied the diagram becomes a thicket of thin branches that is hard to read. That is why it is usually limited to the first few steps or the most common paths. The key point is that behavior flow shows the what, not the why; it says users left the product page without reaching the cart, but the cause must be seen in session replay. Treat it as kin to path analysis and user journey, differing in aggregation level and direction.
