Hook Frequency measures how often each hook type appears across all decoded high-performing ads. A higher frequency means top advertisers reach for this hook type more often, a signal that it reliably captures attention in the first 3 seconds.

Structural Decomposition is how we identify hook types. Every ad is decoded into beats, and the opening beat is classified by its psychological mechanism (curiosity gap, identity trigger, contradiction, etc.). This is not keyword tagging. It is behavioral analysis of how the hook actually works.

Filter by category to see which hooks dominate in your vertical. The distribution shifts significantly between health, SaaS, fashion, and other categories.
