Funnel metrics

Funnel metrics allow you to track and analyze multi-step processes or user flows. By defining the sequence of events in a funnel, you can identify bottlenecks, drop-off points, and conversion rates at each step. This facilitates a granular analysis of user behavior and helps understand experiment effects throughout the user journey.

info

Eppo considers each step of the funnel as a binary outcome: either the user has made it to this step (at least once), or they have not. If a user completes the funnel twice, that is still counted as a single conversion.

Creating a funnel​

Creating a funnel requires you to specify a sequence of events that need to happen consecutively. A natural example of a funnel is the checkout flow for an ecommerce platform:

  • User adds item to cart
  • User clicks checkout button
  • User fills out address
  • User fills out credit card details page
  • User confirms order

Each of these actions are connected to separate events, and we want to understand the user drop-off in each of the steps.

note

Make sure that, if a user hasn’t reached a step, the event in the corresponding table is either missing, or NULL and not marked as 0.

note

Eppo requires the funnel steps to happen in order, but does not care whether unspecified events happen in between the funnel steps.

Time frames​

You can additionally specify a time frame in which a user needs to complete the funnel in order to count as a funnel conversion.

There are three options:

  • No time frame: as long as the user completes the steps in order, it counts as a conversion.
  • Time window from time of assignment: the user has to complete the funnel within the set duration, where the time of assignment starts the clock.
  • Time window from time of first event: the user has to complete the funnel within the set duration, but the clock starts at the time of the first step in the funnel for that user.

Analysis of funnel metrics​

To analyze the effects of an experiment on a funnel, add it as a metric to an experiment as usual. Initially, the funnel will show up in a collapsed format, but can be expanded by clicking the carrot.

Funnel metric analysis

The results show the conversion rate from assignment to each particular step; the overall results thus are the same as the results for the last step. The popover shows additional details:

  • drop-off from the prior step indicates what fraction of users who made it to the previous step in the funnel did not make it to this step
  • survivors are the total number of users that made it all the way to this step in the funnel.

Funnel Steps​

The funnel steps visualization shows how each step of the funnel converted (cumulatively). The solid bars represent the conversion from assignment into the experiment and the gradient represents the drop-off. You can view further details and the survivor count in the tables below. Funnel Steps

Funnel Lift​

The funnel lift visualization shows for each step the relative percent lift in comparison to the control variant.
