What is a hook?

The single most important part of any post — and the one that decides your reach.

A hook is the first one to three seconds of a video (or the first line of a post) that gives someone a reason to keep watching. It works by promising tension, a payoff, or a question the viewer needs resolved — before any setup. On short-form platforms the hook largely decides watch-time, and watch-time decides reach.

Why the hook decides everything

Short-form algorithms reward watch-time and completion. If the first seconds don't earn attention, the post falls below the account's own baseline and distribution stops. The posts that beat their baseline almost always share a strong, specific hook.

FAQ

How long should a hook be?

On video, the first 1-3 seconds; in text, the first line. It must promise a reason to stay before any context.

What makes a good hook?

Specificity and tension: a result, a number, a conflict or an open question in the opening moment.
