Question: Your client has a documentary film coming out next month. They have three separate 30-second promo videos and want to identify which ad viewers watch to the end most often. To prioritize showing that ad, what type of video creative optimization would you use in Display & Video 360?
- Optimize for clicks
- Optimize for completions
- Optimize for conversions
- Optimize for time spent on-screen
Explanation
Video creative optimization in Display & Video 360 can prioritize ads expected to finish playback while audible and viewable. The relevant video metric is Completions, which identifies creative variants more likely to be watched through the end. This setting shifts delivery toward the strongest-performing promo among the available 30-second videos. It is suited to video line items with multiple video creatives assigned.
Why the other options are incorrect
Optimize for conversions prioritizes conversion actions, not completed video playback.
Optimize for time spent on-screen favors ads likely to remain on screen for at least 10 seconds, not full viewing.
Optimize for clicks prioritizes click activity rather than completed video views.
