Question: A nursery wants to maximize the number of impressions that are actually seen for their annual sale while staying within a $3 target. Which optimization strategy should they select?
- vCPM
- CPA
- Custom bidding
- Maximize conversions
Explanation
vCPM is the correct strategy because Display & Video 360’s brand-focused automated bidding can maximize viewable impressions and optimize toward a target viewable CPM. That directly matches a goal of getting as many impressions actually seen as possible while aiming to stay near a $3 efficiency target. Google also ties this optimization to Active View, which is the measurement system used to determine whether an impression was viewable. In this scenario, the objective is viewability efficiency, not conversion efficiency or bespoke scoring logic. Google Help+1
Why the other options are incorrect
Custom bidding is used when an advertiser wants advanced control to score impressions with custom logic, not when the main goal is maximizing viewable impressions at a target viewable CPM. Google Help+1
CPA is a conversion-focused bid strategy, so it optimizes toward conversions rather than viewable exposure. Google Help+1
Maximize conversions is also a conversion-focused strategy, which does not align with a viewability objective. Google Help+1
