Within Display & Video 360, what audience types can you use for a YouTube connected TV (CTV) campaign if you want to reach specific audiences?

For YouTube CTV campaigns in Display & Video 360, Programmatic Guaranteed is the primary audience type for reaching specific audiences. This deal type allows advertisers to secure guaranteed impressions at a fixed price, directly with YouTube, and apply audience targeting. While Private Auction and Open Auction are common in DV360 for other inventory, YouTube CTV inventory for audience-targeted buys is primarily accessed through Programmatic Guaranteed deals. "Private deals" is a general term and less specific than Programmatic Guaranteed in the context of YouTube CTV audience targeting.
