Denise has just set up of a call-tracking service and uploaded her first batch of conversions. How does Denise report on these offline conversions in DoubleClick Search?

To report on offline conversions in DoubleClick Search (DS), Denise needs to create a custom Floodlight column. This column allows her to select the specific Floodlight activities that track her uploaded offline conversions. Once created, this column will display the data for those offline conversions within her DS reports. The other options are incorrect because: She does not necessarily need agency manager or advertiser manager access to report on existing data; standard user access is often sufficient for reporting. "Specifying offline activity as the conversion source" is not a direct reporting action in DS; rather, the data source is defined by the Floodlight activity itself. A formula column is used to manipulate existing data, not to introduce new data sources like offline conversions.
