What is Hook rate?
Hook rate is the percentage of people who keep watching past the first three seconds of your video ad: 3-second video views divided by impressions, times 100. On Meta it's a leading indicator of creative strength — it measures whether your opening stops the scroll, long before conversion data has accumulated.
Formula
Hook rate = (3-second video views ÷ impressions) × 100
Example
A video ad gets 10,000 impressions and 2,800 three-second views → hook rate = (2,800 ÷ 10,000) × 100 = 28%. A second version with a stronger opening hits 45% on the same audience — a clear sign its first frames stop more people, which usually flows through to a lower cost per result.
Why it matters
The first three seconds decide whether anyone sees the rest of your message, so hook rate is the earliest read on whether a creative will work — you can spot winners and losers within hours, before enough purchases accumulate to trust CPA. Because Meta rewards attention-grabbing creative with cheaper delivery, a weak hook rate quietly raises CPM and CPC and caps everything downstream, which makes it one of the most useful metrics in creative testing.
How to use and improve it
Lift hook rate by front-loading the payoff: open on movement, a pattern interrupt, a bold claim, or the exact problem your audience feels, and put the offer or emotion in the first frame rather than after a slow intro. Test several openings against the same body, read hook rate within the first day, and cut weak hooks before they waste budget. Geniusko's AI can generate multiple video hook variations to test quickly.
Frequently asked questions
What is a good hook rate for Facebook and Instagram video ads?
It varies by format, placement and audience, so there's no universal figure. Judge each creative against your own account's typical hook rate and prioritise the openings that clearly beat your baseline.
What's the difference between hook rate and CTR?
Hook rate measures whether people keep watching past three seconds (attention on the video); CTR measures whether they click through to your site (intent to act). A creative can have a strong hook rate but weak CTR if the opening grabs attention that the offer then fails to convert.
How do I improve my hook rate?
Rework the first three seconds: open with motion, a pattern interrupt, a bold statement, or the specific problem your audience has, and show the offer or emotion immediately instead of a slow branded intro. Test multiple openings on the same video body.
Why is hook rate useful in creative testing?
It's a fast leading indicator — you can read it within hours of launch, long before conversions build up. That lets you cut weak creatives early and pour budget into the openings that stop the scroll, tightening the whole testing cycle.
