You're planning to run a Google video campaign with an awareness goal, and you want to measure the following: how many people were served your ads and how many times they were each served across devices and formats. In addition to fundamental video metrics such as 'Video played to', what measurement solution should you use?

The selection is correct because unique reach and frequency metrics provide the specific, deduplicated data required to understand how a campaign is performing against its awareness goals across a multi-device landscape. While standard metrics like "Video played to" track depth of engagement within a single ad instance, unique reach uses Google’s sophisticated statistical modeling to count the actual number of individual people—rather than just cookies or devices—who saw your ad. Simultaneously, the frequency metric reveals the average number of times those unique individuals were exposed to your message. This combination is essential for an awareness strategy, as it allows you to ensure you are casting a wide enough net to find new customers while also monitoring for "ad fatigue" to ensure your message remains impactful and efficient without being over-served to the same audience.
