Proof density
The number of credibility signals (results, data, demos) per minute of video.
Proof density is a retention metric. The more often a viewer encounters proof — a screenshot, a number, a before/after, a demo — the longer they stay.
Channels in business, finance, education and tech under-index on proof density and over-index on opinion. Reversing that ratio is one of the highest-leverage edits available.
Proof can be visual (screenshots), numerical (results), or testimonial (real names). Visual proof outperforms the others in short-form.
Why it matters
Adding one extra proof element per minute typically lifts AVD by 8–15 percent and trust-driven CTR on the next video by 5–10 percent.
How to improve it
- 01Audit your last 5 videos. Count proof events per minute.
- 02Aim for at least 1 proof event per 30 seconds.
- 03Cut anywhere proof density drops below threshold.
