Hook IQ

A composite score predicting how well a hook will retain viewers past the first decision point.

Hook IQ is ViralHookAnalyzer's composite score for a single hook. It blends pattern interrupt density, promise clarity, curiosity gap strength, and emotional valence.

Scores range 0–100. Hooks scoring 80+ have a measurable hook rate advantage in production.

Hook IQ should be calibrated per niche; what scores 75 in finance may behave like 85 in beauty.

Why it matters

Hook IQ acts as a pre-publish guardrail. Channels that consistently publish 75+ IQ hooks compound faster than those that don't.

How to improve it

  • 01Set a minimum hook IQ threshold per channel.
  • 02Test 3 hooks per script and pick the highest IQ.
  • 03Track post-publish hook rate against pre-publish IQ to recalibrate.
