Definition
Hook rate is the share of viewers who stay engaged through the first seconds of a video ad (platform definition varies). It is an early creative quality signal.
How to use it
- Use hook rate with CTR and CVR to avoid optimizing only for views.
- Test hooks as isolated variables (same offer, different first 2-3 seconds).
- Compare hook rate by audience to see which segments respond to the opener.
Common mistakes
- Optimizing hook rate without confirming downstream conversion quality.
- Comparing hook rates across platforms with different definitions.
Measured as
Measure Hook Rate with a fixed attribution window, conversion event, and spend basis before comparing campaigns or creative tests.

Operator takeaway
- Use hook rate with CTR and CVR to avoid optimizing only for views.
- Test hooks as isolated variables (same offer, different first 2-3 seconds).
- Compare hook rate by audience to see which segments respond to the opener.
- Use Hook Rate only inside a stable attribution rule, conversion definition, and time window so campaign comparisons stay honest.
- If performance changes, check whether the metric moved for a real business reason or because the measurement setup changed underneath you.
