The short answer
Write the hook last, and make it the most specific true thing the post delivers, said in the first second or the first line. Show or say the result, the question, or the moment itself; cut the greeting, the logo and the setup. Then check it against the platform’s own number for openings: Instagram’s skip rate for Reels, or the intro figure in YouTube’s retention report.
The first seconds carry more weight every year. Metricool’s 2026 study of 799,718 YouTube videos found the average Short was watched for about 16 seconds, roughly 67% less than a year before. A hook has about a second to earn the next fifteen.
What the first seconds must do
A hook has one job: give the viewer a reason to keep watching or reading that is specific to this post. A generic opening (“Hey guys, today I want to talk about…”) could start any video, so it gives no reason at all. A specific one (“This is why your bread comes out flat”) tells the right viewer they are in the right place.
Platforms measure this directly. Instagram reports a skip rate for Reels, the share of viewers who skipped within the first 3 seconds, and Meta lists it in its Instagram media insights. YouTube’s audience retention report shows the intro, the share of viewers still watching after 30 seconds.
Weak hooks, rewritten
The fix is nearly always the same: replace the setup with the specific thing.
| Weak opening | Why it loses people | Stronger rewrite |
|---|---|---|
| “Hi everyone, welcome back to my channel” | Could start any video | “Three mistakes are making your sourdough flat. The second one surprised me.” |
| “Today I want to talk about pricing” | A topic, not a reason | “We raised our prices 20% and lost no customers. Here is what we changed first.” |
| “So I tried something new this week” | No hint of the payoff | Open on the finished result, then rewind to how |
| “Some tips for small businesses” | Too broad to recognise yourself in | “If you run a salon, post this before Friday.” |
| A logo animation | Spends the first seconds on nothing | Cut it; put the brand at the end |
| “You won’t believe what happened” | Promises without saying what | Say what happened, in the first line |
A five-step method
A method that works for video and text:
- Make the post first. You cannot write the hook until you know what the post delivers.
- Write down the single most interesting true thing in it: a number, a result, a mistake, a moment.
- Write five openings that lead with that thing, each a different shape: a result, a question, who it is for, a mistake, the moment itself.
- Pick the one a stranger would understand in one second, and cut every word before the point.
- For video, make the first frame match the words: show the result or the problem on screen as it is said, and add it as on-screen text for people watching without sound.
Hooks for captions and carousels
Text posts and carousels have hooks too. A caption’s first line is what shows before a reader taps to see more, and a carousel’s first frame decides whether anyone swipes. Use the same rule: the specific thing first, the context after. For a carousel, put the promise on the first frame (“5 steps to a cleaner kitchen in 10 minutes”) and make the last frame worth reaching.
Keep the promise
A hook that the post does not keep is clickbait. It wins the first second and loses the viewer soon after, which shows up in the same numbers the hook was meant to raise: a low average watch time, a dip in the retention curve, few shares. Write the hook from what the post actually delivers, and deliver it early.
Test one change at a time
Compare openings across your own recent posts, not someone else’s. Change one thing, the first line or the first shot, keep the rest of the post the same in kind, and compare its skip rate or intro figure with your median. After a month you will know which shapes work for your audience.
Questions
How long should a hook be?
About one to three seconds of video, or one line of text. Instagram’s skip rate counts viewers who leave within 3 seconds, so the point has to land before then.
Should the hook be spoken or written on screen?
Both. Say it and put it on screen in the first frame, so viewers watching without sound get it too.
What is the difference between a hook and clickbait?
A hook promises what the post delivers. Clickbait promises more than it delivers, and viewers leave when they notice, which lowers watch time and shares.
How do I know if my hook worked?
Compare the opening numbers with your own median: Instagram’s skip rate for Reels, or the intro figure in YouTube’s retention report.
