Thumbstop ratio: the number, and what it hides

Another name for hook rate: how often the ad stopped the scroll.

Term
Thumbstop ratio
How it is calculated
3-second video plays ÷ impressions

Why thumbstop ratio matters

The name is more useful than the metric, because it describes the actual physical event you are buying: a thumb stopping. Teams that talk about thumbstop tend to design openings; teams that talk about impressions tend not to.

Worked example

What this looks like with real numbers

Two ads, same product. One opens on a logo sting, the other opens mid-sentence on someone already annoyed about the problem. The logo ad stops 6% of thumbs; the mid-sentence ad stops 19%. Nothing about the offer changed. The second one simply started at a point worth stopping for.

What it does not tell you

Platforms count a 'play' generously. Treat the absolute number as meaningless and the relative number — this ad against your other ads — as the whole point.

The mistake people actually make

Quoting a thumbstop figure from another brand's case study. Platforms count plays generously, so the number only means something against your own other ads.
