You have 3 seconds. That's all the algorithm gives you before your viewer scrolls. Here's how to use them.
On TikTok, Instagram Reels and YouTube Shorts, the algorithm measures retention rate: how many viewers are still watching after 3 seconds, after 15 seconds, and to the end.
If your hook doesn't hold attention, nobody will ever see the rest of your episode — no matter how brilliant it is. A perfect script with a bad hook = 0 views. A mediocre script with an excellent hook = tens of thousands of views.
The hook is not the introduction. It's the reason to keep watching.
1. The impossible situation — "My husband's other wife just walked into my hospital." The viewer needs to know what happens next.
2. The brutal confession — "I've known for 6 months. I said nothing." Instant character, instant tension.
3. The question with no good answer — "Can you save someone you want to see die?" Creates a moral dilemma that the viewer must resolve.
4. The object that says everything — Close-up on a tattoo, a letter, a positive pregnancy test. No words needed.
5. The interrupted action — Character about to do something extreme, cut to title. Forces curiosity about what comes before.
6. The challenge — "Watch to the end. You won't see it coming." Works on retention + algorithm.
7. The reversal — "I thought I knew my husband. Then he walked into my operating room as a patient."
8. The urgent timeline — "In 72 hours, he'll lose everything. And he doesn't know yet."

Try it →The slow intro — "Hi, I'm Sofia, I'm a cardiologist, and today I'm going to tell you..." Nobody waits. Start in the middle of the action.
The vague hook — "Something happened that changed my life forever." Too generic, zero emotional hook.
The long setup — Explaining the context before creating tension. Plant the conflict in the first 3 seconds, explain nothing.
Talking to the camera — Micro-dramas are fiction. The characters talk to each other, never to the audience (except in specific narrative formats).
The slow zoom — Slow movement in the first 3 seconds signals "nothing happens". Cut faster.
Write your hook last. Once you know your episode's cliffhanger, ask yourself: what's the most shocking image or line that could preview this tension without spoiling it?
Test the hook alone, without the rest of the episode. Does it create a question? Does it trigger an emotion? Does it make you want to know more?
If you hesitate between two hooks, keep both. Test them on a real audience before committing to one.
