Hook Rate Calculator
In a feed, you have about three seconds before the thumb moves on. Hook rate measures how often your opening wins those seconds. It is the first number we look at on any paid-social video, because nothing downstream — hold, clicks, conversions — can happen until the scroll stops.
Hook rate = 3-second video views ÷ impressions × 100%. Often called the thumb-stop rate, it measures how often your opening frames stop the scroll long enough to start the video. It is the first gate in the paid-social funnel: a weak hook caps everything that follows, no matter how good the offer is. A hook rate around 30% is widely treated as strong on feed placements, though the number depends heavily on placement, audience and how each platform counts a view.

How to use this calculator
- Pull 3-second video viewsUse the platform’s 3-second view count for one creative. This is the standard short-view metric on Meta; on other platforms use the closest brief-view definition and keep it consistent.
- Pull impressions for the same creativeTake impressions — the number of times the ad was shown — for the identical creative and window. Use impressions, not reach, so the denominator matches how views are counted.
- Read the rate and the bandThe big number is your thumb-stop rate. Below roughly 15% the opening is being scrolled past; around 30% and above is the territory most buyers treat as a strong hook.
- Fix the first three secondsA weak hook is an opening problem: the first frame, the first motion, the first words. Lead with the most arresting moment, add early on-screen text, and make the thumbnail read in a busy feed.
- Export and decideCopy a share link, download the CSV into your creative tracker, or print a PDF for the review where you choose which hooks to scale and which to recut.
RGM Expert Says
Hook rate is the first thing we look at on any paid-social video, because it is the gate every other metric sits behind. You can have a perfect offer, a tight landing page and a generous budget, and none of it matters if the thumb never stops. We tell clients to treat the first three seconds as a separate product with its own success metric, and that metric is the hook rate.
The discipline that pays off is testing hooks in isolation. We will run the same body with four different openings and let hook rate pick the winner before we spend behind the full creative, which keeps the expensive production focused on edits the feed has already proven it will watch. It is far cheaper to lose an A/B test on a three-second opening than to scale a finished video nobody stops for.
The trap is reading hook rate alone. A high hook with a collapsing hold means the opening is writing checks the body cannot cash — you bought a stop you immediately lose. We always pair this number with hold rate, so a strong thumb-stop is judged by whether it leads anywhere, not just by how loud the first frame shouts.
How it works
Hook rate is a simple capture rate: of every time the ad was shown, how often did someone stop long enough to clear the platform’s three-second view threshold.
- 3-second video views — the platform’s short-view count at the three-second mark.
- Impressions — times the ad was shown (not unique reach), for the same creative.
- Worked example: 9,000 three-second views ÷ 30,000 impressions = 30.0% hook rate.
Each platform counts a ‘view’ differently, so a hook rate is only comparable within one definition; see Meta’s advertising help for video metric definitions. The ~30% strong-hook guideline is a paid-social rule of thumb, not a guarantee.
Why the hook is the gate everything sits behind
Paid-social performance is a chain, and the hook is the first link. If the opening cannot stop the scroll, none of the downstream work — the message, the offer, the landing page — ever gets a chance to perform. That is why a low hook rate caps an entire campaign no matter how strong the rest of the funnel is, and why fixing the first three seconds is often the highest-leverage creative change available.
Hook rate also makes creative testing cheap. Because the opening can be tested in isolation, you can find the winning three seconds before committing budget to a finished video. Run several openings against the same body, let hook rate decide, and spend behind the proven hook — a far better use of money than scaling a polished edit the feed will not stop for.
Read it with hold rate, never alone. A high hook and a weak hold means you are paying to stop people who immediately leave; a modest hook with a strong hold means the few who stay are the right audience. The pair, not either number by itself, tells you whether the creative is working — which is why our hook and hold calculators are designed to sit side by side.
Hook rate in context
Hook rate swings with placement, audience, format and how each platform counts a view, so any range is orientation rather than a target. Compare hooks against each other under one definition and against your own history.
| Hook band | Typical read | First lever |
|---|---|---|
| Below 15% | Scrolled past | Rework first frame and motion |
| 15% to 30% | Average thumb-stop | Bolder opening, early text |
| 30% to 50% | Strong hook | Shift focus to hold rate |
| Above 50% | Scroll-stopping | Scale, template, watch frequency |
What buyers say about the hook
Win the first three seconds or you do not get the next thirty — the hook rate is the only gate every other metric sits behind.
