Early tests of ads on YouTube Shorts have shown that they cost about 50% less than TikTok ads and generate longer views, according to a recent case study from video ad agency Precise.TV. The agency, which ran Shorts ads for sneaker maker Asics, Moose Toys and dozens of other clients, was participating in an exclusive experiment on YouTube. The Google platform allowed some brands to target video campaigns solely to Shorts, representing a new way of buying into that channel.
