Which statement best describes view-based view engagement conversions?

• A. Watches the ad for 30 seconds or through the end; 30-day default window.
• B. Counts any impression as a conversion.
• C. Measures clicks only.
• D. Requires user login.

Answer: (D)

View-based view engagement conversions hinge on tying a video view to a real user identity so Google can attribute a later action to the same person. That identity linkage is possible only when the user is signed into a Google account, which allows cross-device and cross-session attribution of the viewed ad to a concrete user. Without a login, there’s no reliable way to connect the view to the person who later converts, so this type of conversion can’t be tracked accurately. The other ideas—a fixed view duration, counting any impression as a conversion, or measuring only clicks—don’t address the essential requirement of identifying the user to attribute the view to a later engagement.
