The gap between a good hook and a great one is bigger than the gap between a bad one and a good one
Reels we scored 10 on the hook get a median 728,461 views against 106,397 for a 9. Measured from Scrptly analyses on 16 September 2026.
What the numbers say
A 7 and an 8 are worth about the same: 28,628 and 24,744 median views, and the 8 is marginally lower. The step from 8 to 9 multiplies median views by 4.3. The step from 9 to 10 multiplies them by another 6.8, to 728,461. Per follower, which takes account size out of it, the same shape holds more gently: 0.42, then 0.52, then 1.36. A 10 is the only score whose median reel gets more views than its creator has followers.
The useful reading is that hook effort is not linear. Moving an opening line from weak to competent buys almost nothing. Moving it from competent to unmistakable is where the whole return sits, and most drafts stop at competent because competent feels finished. Look at the seven below and notice what none of them do: not one sets the scene, names the creator, or explains what the video is about. Five of them are incomplete on purpose, in the sense that the line only makes sense once you keep watching. That is the mechanism. A 10 does not describe the video, it opens a gap the video then has to close.

The measurement
Every deduplicated reel carrying a hook strength score, grouped by that score. Median views is the median within the group. Views per follower is the median of the per reel ratio, which controls for the size of the account. Scores of 6 and below are left out: their groups hold between 1 and 13 reels each, and a median of one reel is not a measurement.
| Hook score | Reels | Median views | Median views per follower | Mean retention score |
|---|---|---|---|---|
| 7 out of 10 | 100 | 28,628 | 0.35 | 72.3 |
| 8 out of 10 | 363 | 24,744 | 0.42 | 75.6 |
| 9 out of 10 | 1,489 | 106,397 | 0.52 | 81.2 |
| 10 out of 10 | 123 | 728,461 | 1.36 | 87.4 |

The hook is pulled out on its own: Why do some people squat like this and others like this? The breakdown scores it 10 for hook strength and 88 for retention, and names why it works: the question is asked about the viewer rather than the creator, it is answerable in the length of the reel, and it sets up a comparison the reel then has to resolve. The structure is labelled as a two subject explainer: pose the question in 3 seconds, introduce subject one at 0:03, subject two at 0:17, resolve the comparison at 0:31, then give each subject a fix at 0:39.
Score returned: 10. 10 of 10 on hook strength, 88 on retention. The reel ran 56.9 seconds and earned 10,558,203 views from an account with 1,283,635 followers.

What to do next
- Score your opening line before you film, not after. Two script evaluations are free, and the number is only useful while the script can still change.
- If you land an 8, do not ship it and hope. The data says an 8 performs like a 7, and the return only appears at 9 and above, so the rewrite is worth more than the shoot.
- Steal the shape rather than the subject. Ask the question about the viewer, make it answerable inside the runtime, and set up something the rest of the reel has to resolve.
