What is a hook in a UGC ad?
A hook is the first two to three seconds of an ad: the opening line, first shot and on-screen text that make a viewer stop scrolling. In UGC ads it's usually a spoken line the viewer recognises themselves in, such as a specific problem, a surprising claim or a direct question.
The three layers of a hook
- Spoken line: what the presenter says first, e.g. "Is your dog slowing down on the stairs?"
- First shot: what's on screen in frame one, ideally the presenter mid-action or the product in use, never a logo.
- On-screen text: the hook repeated as a caption, for people watching muted.
The strongest hooks make all three say the same thing.
Why the hook matters so much
In short-form feeds, people decide in a moment whether to keep watching. If the opening doesn't land, nobody hears the problem, sees the product or reaches the call to action. That's why media buyers measure hook rate, the share of impressions that watch at least three seconds, separately from sales.
Hook types
- Problem call-out: names a frustration the viewer has.
- Question: asks something the viewer answers "yes" to in their head.
- Time stamp: "2 a.m. and still scrolling?"
- Contrarian: challenges a common belief.
- Story opener: "I almost returned this…"
- Result or demo first: shows the outcome, where claims allow.
A hook is cheap to test
Because it's only the first few seconds, you can swap hooks on the same ad body and learn which opening works without making a whole new ad. Our hooks guide has 48 example lines sorted by angle.
Every ad we deliver at ScrollStop Labs comes with alternate opening hooks, so you can run this kind of test without a reshoot.
