Entry / Exit Analysis

Entry / Exit Analysis lets you use the entry (first) or exit (last) in-session dimensions across different types of analysis.

Supported metric types

Entry / Exit analysis supports the following metric types:

• Uniques: The count of unique users
• Event totals: The total number of events
• Session totals: The total count of sessions
• PROPSUM: The sum of a group-by property value

Enable Entry / Exit Analysis

Apply Entry or Exit semantics to any supported metric type in the Data Table.

To enable this analysis:

1. In a data table with at least one event or metric, click the Options menu in the header of the column you want to enable the analysis on.
2. Click Enable Entry/Exit Analysis in the options menu. The Enable Entry/Exit Analysis dialog appears.
3. Select how to apply group-by properties to the column:
   • Default: Uses the standard group-by setting for the column
   • Entry: Groups data by the first non-null property value of an active event in a session that contains the specified event.
   • Exit: Groups data by the last non-null property value of an active event in a session that contains the specified event.

4. Click Apply.

Processing flow

For each session that contains the event specified in the column:

1. Amplitude identifies all relevant sessions.

2. For each session:

   • Amplitude extracts the first property value of an active event for Entry Analysis.
   • Amplitude extracts the last property value of an active event for Exit Analysis.

3. Amplitude uses these values to compute session-based metrics.

Calculations

Amplitude uses the following formulas to compute the metrics that support Entry and Exit analysis:
