Hook rate measures what percentage of viewers who started watching a video continued past the 3-second mark, assessing how well your opening retains initial attention.
Hook rate is calculated as 3-second video views divided by total video plays (not impressions). While thumb stop rate measures whether a user pauses their scroll at all, hook rate measures retention among those who've already started watching. It captures the quality of your hook for people who gave your ad a chance.
The distinction matters because some video plays are auto-triggered by platform algorithms before the user has made a conscious choice to watch. Hook rate filters for genuine early retention: did the viewer who started watching find the first 3 seconds compelling enough to continue?
Hook rate is widely used in TikTok performance analysis and increasingly in Meta creative reporting. It's more sensitive to hook quality than thumb stop rate because it removes the noise of impressions-without-plays from the denominator.
Hook rate reveals whether your creative's opening is doing its job once a viewer is in play. A low hook rate with decent thumb stop rate means your thumbnail or first frame stopped the scroll, but the next 2 seconds lost the viewer. This distinction tells creative teams whether to fix the hook narrative (hook rate problem) or the static/opening visual (thumb stop problem). They're two different fixes.
Example
“A DTC brand's video gets 10,000 plays but only 3,200 3-second views, a 32% hook rate, revealing that the voiceover intro is slow and needs to start with the payoff instead.”
