Final answer:
In the context of Data Transfer services for online advertising, metrics like Active View and Cross-environment conversions are generally available to advertisers, whereas the Designated Market Area (DMA) ID metric is not included in this type of raw event-level data service.
Step-by-step explanation:
The Data Transfer in the context of online advertising is a service that provides raw data logs that reflect all events that occur on a digital platform, such as impressions, clicks, and conversions. This type of data service is generally used by advertisers and marketers who wish to perform custom data analysis for which standard reporting doesn’t suffice.
The metrics available in Data Transfer often allow for a deep dive into advertisement performance and user engagement. Active View is a metric that is available in Data Transfer services which measures the viewability of an ad, namely how long the ad was displayed on the screen and whether it was seen by the user. Cross-environment conversions are also typically available, enabling users to track conversions across different devices such as mobiles and desktops.
The metric that is NOT available in Data Transfer would be Designated Market Area (DMA) ID. The DMA ID is used to identify geographical regions where the audience is more likely to consume certain media, and while important for targeting and segmentation, it is generally not included in the raw event-level data provided by Data Transfer services.
