Hook
The opening few seconds of a video ad, designed to grab attention and stop the viewer from scrolling past.
Definition
The hook is the very start of an ad — usually the first one to three seconds — whose only job is to earn the next few seconds of attention. It can be a bold claim, a question, a surprising visual, or a relatable problem stated out loud.
Why it matters
On fast-scrolling feeds, most viewers decide almost instantly whether to keep watching. A weak hook means the rest of the ad — however good — never gets seen. This is why advertisers often test many hooks against the same core message.
How it applies to UGC ads
Hook testing is one of the most common reasons teams want lots of creative variants. With UGCABC you can keep a script's body the same and swap just the opening line across multiple renders, so you can find the hook that holds attention without re-shooting the whole ad.
