YouTube is experimenting with new ways for advertisers to buy masthead ads, which is the most prominent ad unit on the home feed.
A YouTube masthead ad is a video unit that appears at the top of the home feed on mobile and desktop.
Masthead ads are usually reserved by one advertiser per country per day.
YouTube is now offering the option for advertisers to buy masthead ads on a cost-per-thousand (CPM) basis.
In addition, advertisers can customize the audiences they want to see the ad.
