Quick definition
A hook is the first line, frame, or few seconds of a post, engineered to stop the scroll — it earns the attention the rest of the content needs to work.
The hook is whatever your audience encounters first: the opening seconds of a video, the first line of a caption before the truncation fold, the first post of a thread, the cover slide of a carousel. Its only job is to interrupt a scroll and buy the next few seconds of attention. Classic hook patterns include direct questions, bold or contrarian claims, curiosity gaps (“nobody tells you this about…”), specific numbers, and visual pattern interrupts.
Feeds audition content constantly, and viewers issue verdicts in moments. Platforms have repeatedly indicated that held attention — watch time, completions, early engagement — influences how widely a post is distributed, so a weak opening doesn’t just lose the viewers who scroll past; it suppresses the post’s reach to everyone else. Text gets the same treatment from truncation: most feeds show a line or two of a caption before “more,” so the first sentence is the only one with guaranteed delivery.
Take two cuts of the same 30-second clip. Version A opens with a four-second logo animation; of 100 viewers, 40 are still watching at second five. Version B opens mid-action with the payoff stated up front; 70 of 100 survive the same mark. Every downstream number — average watch time, completions, shares, CTA clicks — inherits that 1.75× difference in surviving viewers, before content quality even gets a vote.
Write the body first, then steal its single most interesting sentence for the opening. Lead with the payoff, not the setup; cut throat-clearing intros entirely. Then test deliberately: rotate hook styles — question, claim, number, story — across comparable posts, and read the results in retention curves and engagement. Keep a swipe file of openings that worked; strong hooks are reusable patterns, not one-off luck.
