The percentage of video viewers who stop scrolling to watch your ad.
Why It Matters
Thumb-stop ratio measures whether your video's visual impact is strong enough to interrupt passive scrolling. It's the ultimate test of your creative's stopping power. High thumb-stop means more impressions convert to actual views, directly improving your cost per engaged viewer.
Practical Example
Scenario
A brand's standard product video shows 15% thumb-stop ratio. They create a version opening with a dramatic product transformation shot.
Result
Thumb-stop jumps to 38%. The same ad spend now generates 2.5x more engaged viewers and 40% lower CPA.
Pro Tips
- 1Open with visual contrast: bright colors, unexpected imagery, or dramatic motion that stands out in the feed
- 2Use faces and eyes—humans are wired to stop and look at other humans
- 3Preview the transformation or result immediately, not after context-setting
- 4Test thumbnail/preview frames specifically if your platform shows static previews before autoplay
Common Mistakes to Avoid
Opening with subtle, muted visuals that blend into the feed instead of standing out
Prioritizing brand guidelines over stopping power—sometimes you need to break conventions
Not measuring thumb-stop ratio separately from overall video metrics
