Short-form Hook Guide

Short-form Hook Timing Guide

8 principles for hooks that hold viewers inside the 3-second window.

1. Why Seconds 0–3

  • Shorts, Reels, TikTok all run on auto-play, muted, vertical-scroll. Frame 1 decides retention.
  • TikTok internal data: 37% of viewers bounce within 2 seconds. Clear the 3s mark and completion triples.
  • Meta Reels guideline: first-3s retention is the top weight for feed distribution.

2. Hook Window by Video Length

  • 15s: Hook must land in 1.5s — "one breath, one frame."
  • 30s: Up to 2s. Hook plus one beat.
  • 60 / 90s: Up to 3s, but you must promise the payoff before second 3.

3. Four Core Levers

  • Specificity — numbers: "5 ways", "3 min", "30 days".
  • Personalization — "If you're [audience]", "Monday morning, you know this".
  • Tension — questions, twists, forbid, cliffhanger.
  • Payoff — a clear reason the finish is worth it.

4. First-Frame Visual Checklist

  • Caption: Assume muted playback. Always caption the hook line.
  • Strong visual: movement, contrast, crop. No static insert in second 1.
  • Human face: opening without a face drops retention ~15% on average.
  • SFX: a 0.3s thump / ding transition lifts attention hard.

5. Anti-patterns to Avoid

  • "Hey guys, today we're..." — instant second-1 bounce.
  • Context first — push "so last week..." into the body.
  • Clickbait + content mismatch — retention dies, ranking follows.
  • Vague hooks ("this is huge") — no specificity = no hook.

6. Hook → Body → CTA

  • First 3s hook → middle body (split payoff) → final CTA.
  • Release the hook's promised info near the midpoint to flatten the retention curve.
  • CTA can live in the last 2s — the algorithm stops counting drop-off at the very end.

7. A/B Testing

  • Draft 2–3 hooks, compare with the Hook Score on this page. A 2+ point gap matters.
  • After upload, track 3s-retention and completion rate in native analytics.
  • Re-upload the same body with a new hook — especially effective on TikTok.

8. Platform Tips

  • YouTube Shorts: text hooks crush. Open with a thumbnail-style caption.
  • Instagram Reels: visual hook + short caption. Trending audio matters.
  • TikTok: full-screen text wall + trending sound. Duet / stitch reaction hooks pay off.
