You know that mixing video ad formats is a good idea, but you aren't sure which mix is most appropriate for your goal of driving maximum reach and video completions. What mix of awareness ad formats should you use?

The selection is correct because combining skippable in-stream ads and non-skippable in-stream ads creates the most effective synergy for achieving maximum reach and video completions within an awareness strategy. Non-skippable in-stream ads, which are limited to 15 seconds, guarantee that the entire message is viewed, directly securing high completion rates for core brand storytelling. Meanwhile, skippable in-stream ads extend total reach and scale by allowing users to choose their level of engagement, providing the algorithm with "cost-per-view" efficiency where you only pay for significant watches. Together, these formats allow Google’s machine learning to optimize the mix based on real-time viewer behavior, ensuring that you capture the broadest possible audience while maintaining a high volume of full-length video views that shorter formats like bumper ads cannot provide.
