In-video ads on YouTube
In-feed video ads include an image thumbnail, a headline, and up to 2 lines of text (depending on where the ad appears). When a viewer interacts with the thumbnail, they’re taken to the ad’s landing page or website. In certain environments, hovering on the thumbnail will then lead to muted autoplay of the video ad.
