Measure whether your title and thumbnail promise is actually fulfilled in the first 30 seconds.
When viewers see a title and thumbnail, they expect a specific outcome, answer, or experience. That expectation is the click promise. When the opening confirms it quickly, viewers know they chose the right video.
The title states the outcome, the thumbnail adds curiosity or proof, and the first 30 seconds confirms both. If they tell different stories, a strong click can still lead to an early exit.
The score combines title–hook alignment (30%), promise clarity (20%), thumbnail–title complementarity (15%), time to value (15%), specificity (10%), and honesty (10%).
Curiosity withholds the answer while representing the real topic accurately. Clickbait promises an unsupported result or creates an expectation the video does not fulfill.
It is how clearly the first 30 seconds fulfill the expectation created by the title and thumbnail.
It weights title-hook alignment, promise clarity, thumbnail complementarity, time to value, specificity, and honesty.
