What kind of data would be used to target ads to people who have recently searched for information about soccer matches?

First- or third-party data segments are used to target ads to people who have recently searched for information about soccer matches. This data includes information like search history, website visits, and app usage, which can be collected directly by the advertiser (first-party) or by external data providers (third-party). This allows for precise targeting based on demonstrated interests. DCM IDs are used for tracking and reporting within DoubleClick Campaign Manager, not for audience targeting. Dynamic targeting keys are used to populate dynamic creative content based on user attributes, not to define the audience itself. User profile data is a broad category that can include demographic information, but "first- or third-party data segments" more specifically describes the mechanism for leveraging search behavior for targeting.
