What Is a Hook in a Video?

A hook is the first line or first seconds of a video, written to make people stay for the rest: a question, a surprising fact or the start of a story.

On TikTok, Reels and Shorts, people decide in a second or two whether to keep watching. The hook is what earns that second. Common hooks open with the most surprising fact, a question the video answers, the middle of a story, or a promise of what the viewer will learn.

YouTube Studio shows how an opening works: its retention report has an intro figure, the share of viewers still watching after the first 30 seconds of a long video, and YouTube says a high one can mean the opening matched what the title and thumbnail promised. On Shorts, the gap between views and engaged views shows how many people swiped away at once.

A good hook promises only what the video delivers. A hook that tricks people raises views for a moment and lowers retention, and a viewer who feels tricked does not come back.

Questions

How long should a hook be?

Short: one sentence, or the first 1 to 3 seconds of a short video. It should say why the next seconds are worth watching.

What makes a good hook?

A real surprise, question or story from the video itself, said in plain words. It works when the video then keeps its promise.

How do I know if my hook works?

Look at retention in the first seconds. On YouTube, the intro figure and, for Shorts, engaged views against views show how many stayed.

Is clickbait a hook?

A hook that promises what the video does not deliver is clickbait. It can raise views once and lower retention and trust after.

Should the hook be spoken or written on screen?

Both work best together on short videos: say it in the first line and show its key words on screen, for viewers who scroll with the sound off.
