A hook is the opening seconds of a short-form video, built to make someone who is scrolling stop and keep watching. It carries no plot of its own — its only job is to earn the next three seconds.
Because a video plays before anyone has decided to watch it, the hook does the work a headline does elsewhere: on-screen text, a striking first frame, or an opening line that promises something specific.
A weak hook is the single most common reason a well-made video underperforms, which is why it is worth testing on its own rather than blamed on the topic.
It is also the cheapest thing to test on purpose: filming two openings for the same idea and comparing what each one did is a smaller experiment than reshooting the whole video, and it isolates the one variable that actually explains most of the difference.
A common mistake is judging a hook by whether it is clever rather than by whether it made someone stop — a hook's only job is earning the next three seconds, and a line that is interesting to the person who wrote it is not automatically one that stops a stranger mid-scroll.
A weak hook is also easy to misdiagnose as a weak topic: a video reshot with the same idea and a different opening line can turn a quiet result into a strong one, which is why testing the opening on its own, before touching anything else, is usually the cheaper first move.
Where it comes from
Hootsuite's own guide to short-form video frames it the same way — an opening built to draw an audience in before the rest of the video plays.
Starting your video with a strong hook, through on-screen text, eye-catching visuals, or with a tantalizing story, can help draw your audience in and keep them watching.
