GA4 Event Metrics to BigQuery Mapping

GA4 BigQuery

Here’s a breakdown of GA4 event metrics and their corresponding BigQuery fields:

GA4 Event MetricsWhat it isBigQuery Field Name
Key eventsMeasures how frequently users trigger events that have been designated as key events.Not directly available in BigQuery export schema; requires custom logic based on event names designated as key events.
Event countThe total number of times any event is triggered by users across the platform.COUNT(event_name)
Event count per userRepresents the average number of events each active user triggers.COUNT(event_name) / COUNT(DISTINCT user_pseudo_id)
WHERE /* Add filter based on user activity data for the timeframe */
Event valueThis metric aggregates all value parameters associated with events, capturing both realized and potential contributions beyond direct purchases.SUM(event_params.value.double_value) WHERE event_params.key = 'value'
Events per sessionThe average number of events that occur within a session, indicating user engagement per session.COUNT(event_name) / COUNT(DISTINCT event_bundle_sequence_id)
First opensCounts the number of times the application is opened for the first time by new users.COUNTIF(event_name = 'first_open')
First visitsTracks the number of first-time visits to your website by new users.COUNTIF(event_name = 'first_visit')

Points to consider

There is no corresponding field in the BigQuery export schema that flags an event as a key event. 

To calculate this metric, you would need to define which events are considered key events within your GA4 configuration and then count occurrences of those events.
