How to use the ad hook generator
Describe the product and the result it delivers.
Add the audience if you know it; hooks get sharper when they can call someone out.
Generate, then read the hooks out loud. They are written to be spoken.
Film or design the best three and test them against the same body of the ad.
Example brief and output
Example brief
- Product: a posture corrector worn under clothes for 20 minutes a day.
- Audience: people who sit at a desk all day.
- The output mixes hook types, for example a callout ('Desk workers, check your shoulders right now'), a question ('When did you last sit up straight without thinking about it?') and a mistake hook ('Stretching at night is not fixing your posture').
Hook types and when to use them
Each generated hook is labelled with its type, so you can test structures rather than near-identical lines.
| Hook type | When it works |
|---|---|
| Callout | Names the viewer ('New runners…'). Strong when the audience is specific. |
| Pattern interrupt | An unexpected line or visual. Useful in crowded feeds. |
| Question | Invites a mental answer. Works when the problem is familiar. |
| Bold claim | Leads with the outcome. Needs proof within the next few seconds. |
| Story | Starts mid-scene. Suits UGC and founder-led ads. |
| Mistake | Corrects something the viewer does, positioning you as the expert. |
| Before and after | Shows the change. Check Meta's policies for sensitive categories. |
| Curiosity | Opens a loop the ad closes. Avoid promises the product cannot pay off. |
Hooks are visual too
In video, the hook is the first frame as much as the first line. Pair each line with an opening shot that shows the product in use, the problem, or a surprising action, and add on-screen text, because many people watch with the sound off.
Testing hooks efficiently
Keep everything after the first few seconds the same and swap only the opening; that isolates the hook as the variable. Use hook rate (3-second video plays divided by impressions) and hold rate as early signals, then judge on CPA once there is enough data.
- Test three to five hooks per concept.
- Retire hooks that clearly lose and iterate on the winner's structure.
- Save hooks from long-running competitor ads to a swipe file and study their structure.
Questions and answers
What is an ad hook?+
The opening line or moment of an ad, designed to stop the scroll and earn attention for the rest of the message. In video it is usually the first one to three seconds.
How long should a hook be?+
Short enough to say in about three seconds, which usually means under 15 words. The generator keeps every hook under that length.
What is a good hook rate?+
Hook rate, usually 3-second video plays divided by impressions, varies by format, placement and audience. Compare hooks against each other and against your account's typical figure rather than against a universal benchmark.
Can I use these hooks for TikTok?+
Yes. They are written in a spoken style that suits TikTok, Reels and Stories, and they also work as the first line of primary text in static ads.
How many free generations do I get?+
Guests get a small number of free generations each day. Create a free account to keep generating and to use the AI studio inside PixelSpyer.
Where can I find hooks that already work?+
Look at ads that have been running for a long time in your niche, since longevity is a reasonable sign an ad is profitable. PixelSpyer's ad library lets you search by niche and see how long each ad has been live.
