In DV360 reporting, if no specific attribution model is manually selected for a data set, which model is used as the default?
- Time decay
- First interaction
- Linear
- Primary (bidding)
Explanation
In standard Display & Video 360 reporting, the default attribution setting is the Biddable Conversions model when no attribution model is explicitly selected. Google states that if no attribution model is selected, the report uses the biddable conversion model by default. This model is based on the Primary attribution model and respects the Floodlight activity selections applied at the line item level. That is why the correct choice is the primary bidding model rather than another reporting-only attribution rule. Google Help
Why the other options are incorrect
Time decay is an optional attribution model and is not the default model automatically applied in standard Display & Video 360 reports when none is selected. Google Help
Linear is also a selectable attribution model, but Google does not identify it as the default reporting model in this case. Google Help
First interaction is a separate attribution option and does not serve as the automatic default for standard Display & Video 360 reporting. Google Help
