Add Funnel Analysis

Funnel Exploration

1. Obtain the sequence of the steps and the conversion event. The steps should happen consecutively over the time.

   step1 -> step2 -> ... -> conversion

   A step can be both an event triggered by the user or just a user being in a given location at a given time. This can be set with arguments like event_type and location stack filtering when running the funnel function. We can use a function similar to top_product_features_before_conversion (that internally uses conversions_in_time and conversions_counter) to get the relevant hits before conversion.

2. After calculating the data for each step, we do a breakdown of different metrics:

   • number of users/sessions
   • average duration of the sessions
   • top features, etc ...

3. Construct Sankey Diagram using maybe Plotly (https://plotly.com/python/sankey-diagram/).

For later add:

• max duration between the steps,
• tracking funnel changes over time.
