What are YouTube Shorts?
Short answer
YouTube Shorts are short vertical videos on YouTube, shown in a swipeable Shorts feed and recommended to viewers based on what they watch.
Shorts sit inside the main YouTube app, alongside long-form videos. A channel can post both, and Shorts are often used to bring new viewers to a channel.
Like Reels, Shorts are recommended widely, so a channel with few subscribers can still reach a large audience.
