A media buyer wants to evaluate performance and set up automatic rotation for three different video creatives assigned to one line item. Which setting should they use?

For video line items with multiple assigned creatives, Display & Video 360 uses creative optimization to decide how those creatives rotate before bidding begins. Match bidding strategy is the setting that automatically applies the rotation logic that best aligns with the video line item’s bidding setup, rather than forcing a separate manual optimization choice. Google documents that this option maps the line item’s bidding strategy to the corresponding creative optimization behavior, so rotation stays aligned with the performance goal. That makes it the appropriate setting when several video creatives need to rotate automatically while performance is evaluated in a way that matches the bidding objective. Google Help
