3-Second Hook Design - 2026 Formula

Quick answer: Instagram algorithm measures retention in the first 3 seconds. 30% scroll past - reel suffocates. 80% stay - pushed to 10K more. Use 15 proven hook patterns: pattern interrupt, number, question, scandalous claim, or visual surprise.

15 Working Hook Patterns

1. Pattern interrupt - unexpected movement
2. Surprising number - 90% are doing this wrong
3. Direct question - Why is nobody talking about this?
4. Scandalous claim - I'm leaving Instagram
5. Visual surprise - something weird on screen
6. POV opener - viewer's perspective
7. Before / After
8. Behind the scenes
9. Confession
10. Stitch / Duet hook
11. Countdown
12. Negative - Don't do X
13. Promise - I'll explain in 30 seconds
14. Curiosity gap
15. Direct address

Mistakes That Kill 3 Seconds

• Intro with logo (instant cut)
• Background music before speech
• 3 seconds of silence at the start
• Tiny hook text (illegible on mobile)
