Question: An analyst changes the attribution model for their Google Analytics property from Last click to Data-driven. Which dimensions will reflect this new attribution setting?
- Dimensions related to Google Ads campaigns only (e.g., Google Ads campaign)
- Dimensions without a scope prefix (e.g., Source, Medium)
- Dimensions with the First user prefix (e.g., First user source)
- Dimensions with the Session prefix (e.g., Session source)
Explanation
Data-driven attribution applies to event-scoped traffic-source dimensions used for key event credit assignment. These dimensions follow the attribution model selected in the property settings. First user and Session traffic-source dimensions use paid and organic last click instead. This means attribution model changes affect key event attribution reporting, not user- or session-scoped acquisition dimensions.
Why the other options are incorrect
First user prefix is incorrect because user-scoped dimensions are not affected by attribution model changes.
Google Ads campaigns only is incorrect because the selected attribution model is not limited to Google Ads campaign dimensions.
Session prefix is incorrect because session-scoped dimensions continue to use paid and organic last click.
