1. What makes a scroll-stopping hook
A TikTok hook works by creating an immediate open loop — a feeling of incompleteness that the viewer's brain wants to resolve. The four types that work best for e-commerce:
1. Pain/frustration: "I wasted £200 on gym bags before I found this one" 2. Curiosity gap: "Nobody talks about the real reason your hair keeps breaking" 3. Bold claim: "This $12 tool does what a $400 blender does" 4. Direct challenge: "If you're still doing your skincare routine without this, stop"
The hook doesn't have to be about the product directly — it just needs to make the right person think "wait, that's me" or "I need to know more".
2. The 120-character rule
TikTok captions and on-screen text have practical length limits. More importantly, hooks work best when they're short and punchy — a hook that takes 5 seconds to read has already lost most viewers.
Keep hooks under 120 characters. That's typically 10–15 words. Force yourself to be ruthless:
Too long: "If you're someone who really struggles with finding a water bottle that actually keeps your drinks cold all day, you need to see this" Sharp: "Your water bottle isn't keeping drinks cold. This one does for 24 hours"
Fragments are fine. Complete sentences are not required. Punchy wins.
3. Pain-based hooks vs curiosity hooks
These are the two highest-converting hook types for e-commerce, and they work differently:
Pain-based hooks work because they create instant identification. If someone is experiencing the exact frustration you describe, they stop scrolling automatically. Best for products that solve a clear, common problem.
Curiosity-driven hooks work by withholding information. "The reason your [X] isn't working" or "What most people don't know about [Y]" forces the viewer to watch to get the answer. Best for products where the benefit isn't immediately obvious.
Test both for every product. Pain-based hooks typically have higher immediate CTR; curiosity hooks often generate more saves and shares.
4. Native vs salesy
TikTok users are extremely sensitive to content that feels like an ad. Hooks that sound corporate, formal, or like traditional advertising get scrolled past instantly.
Salesy (avoid): "Introducing our revolutionary new blender that will transform your morning routine!" Native: "I can't believe I used to pay £5 a day for smoothies"
The best TikTok e-commerce hooks sound like they came from a regular person sharing a discovery — because that's what organic TikTok content looks like. Even paid ads perform better when they mimic organic content style.
5. Using hooks in video and caption
Your TikTok hook should work in at least two places:
1. On-screen text overlay in the first 1–2 seconds of the video 2. The TikTok caption (which appears below the video)
The on-screen hook is more important — most viewers never expand the caption. But having a strong caption hook helps with viewers who pause, and it adds indexable text for TikTok's search algorithm.
For paid TikTok ads, test 3–5 different hooks against the same video creative. Hook performance varies dramatically by audience, and the winning hook often surprises you.
