Funnel Exploration

Funnel exploration is an analysis tool in GA4 that visualizes the various event stages a user goes through and checks the abandonment rate of each stage. It is used to find conversion bottlenecks.

In funnel exploration, a funnel of up to 10 stages is defined, and the completion rate and number of dropouts between each stage are checked using bar charts and tables. Two types are supported: open funnel and closed funnel. Closed funnels only track users who completed step 1 first, while open funnels include users who entered at any stage.

It is different from Universal Analytics’ goal funnel. GA4 funnel exploration allows segment comparison, so you can view the step-by-step abandonment of new and returning users side by side, and investigate what users who abandoned the funnel did next with path exploration.

When analyzing a hospital reservation system, if you create a three-stage funnel of ‘page view (reservation page) → form start → form submission’, you can immediately see which stage has the most abandonment. Discovering which steps have a high abandonment rate provides a basis for prioritizing UX improvement work for those pages.

Key takeaways

  • Define a funnel with up to 10 sequential events or page conditions.
  • It supports two types: open funnel (entry to any stage is allowed) and closed funnel (entry to stage 1 is required).
  • The number and ratio of users who have dropped out can be visualized by stage, and users who left a stage can be investigated in other explorations.
  • By comparing segments, we analyze funnel performance by new/returning, device, and channel side by side.

Frequently asked questions

Should you use an open or closed funnel?

Use a closed funnel if you want to track the conversion flow strictly in order, or an open funnel if you want to include entry at any stage. Flows where order is important, such as purchases and reservations, generally have closed funnels.

How is it different from Goal Funnels in Universal Analytics?

Although the UA goal funnel was set only on a page view basis, GA4 funnel exploration is defined as event-based, and segment comparison and exit path connection functions are added, making it much more flexible.
