The six signals we score
Every title is graded against the drivers that actually move the algorithm.
Curiosity gap
Does it make viewers desperate to know more?
Emotional pull
Does it trigger fear, excitement or FOMO?
Specificity
Numbers and details beat vague promises.
Length
Ideal length for the platform you picked.
Trending keywords
Power words and search terms that pull clicks.
Actionability
Is the payoff for the viewer clear?
A scored title is step one.
LumeFlux turns the winning idea into a full faceless video: script, voiceover, captions and visuals. Then it learns which of your videos actually get watched to make the next one better.
