title Factor

Curiosity Gap

Whether the title creates an information gap — a feeling that the viewer is missing something they need to know. Measured on a three-level scale from no gap at all to a strong, irresistible pull.

Curiosity gaps are the single most powerful click driver on YouTube. When a viewer feels they almost know something but not quite, the psychological discomfort makes clicking nearly involuntary. But overusing strong gaps without delivering can train your audience to distrust your titles.
