Ranked in these QuestionsQuestion Ranking
Pro Generous free plan
Pro Event Flows visualize popular user paths
Event Flows, an Enterprise level feature, shows a branching user-action path from or towards a certain page/action.
For example, it could show most popular actions performed after landing on a product page or the most popular path towards clicking the buy button.
Compared to funnels, that allow you to track if users follows a predetermined path and where they drop off, Event Flows show what users choose to do instead. And while it's possible to create a funnel for each branching path, that involves a lot of time and some guesswork which is not present in Event Flows.
