Expert strategies
Best Practices Built In
These proven strategies are automatically applied by our AI in every generation.
Aim for 8+ on every video
Hooks scoring 8-10 create immediate curiosity or stakes. If your hook scores below 6, the AI rewrite will show you what you're missing.
Never start with a greeting
"Hey guys, welcome back to my channel" is the single biggest retention killer. Start with the value or the curiosity — save intros for after the hook.
Match your hook to your title
If your title promises "3 mistakes killing your channel," your hook should immediately reference those mistakes. Congruence = trust = retention.
Test multiple hooks
Write 3 versions of your hook and score each. The difference between a 5/10 and 9/10 hook can be the difference between 30% and 70% retention at the 30-second mark.

FAQ
Frequently Asked Questions
Everything you need to know about the YouTube Hook Scorer.
What makes a good YouTube hook?+
The best hooks create immediate curiosity, promise a specific payoff, or establish stakes within the first 5-10 seconds. They make the viewer feel like they'll miss something important if they click away.
How important is the hook for YouTube performance?+
Critical. YouTube's algorithm heavily weights early retention (first 30 seconds). A video that retains 80% at 30 seconds will be recommended far more than one that retains 50%, even if overall watch time is similar.
What hook techniques work best?+
Result teasers ("I went from 0 to 100K subscribers using this"), bold claims ("Everything you know about X is wrong"), and curiosity gaps ("The #1 mistake is something you're probably doing right now") consistently score highest.
Can I use this for Shorts hooks?+
Yes, but Shorts hooks need to be even faster — you have 1-2 seconds, not 5-10. Paste your Shorts opening and the scorer will evaluate it against the tighter retention window.
