How to Write a TikTok Hook That Stops the Scroll

Why hooks decide everything on TikTok

TikTok's delivery system watches early retention. When viewers hold past the opening seconds, the algorithm reads the ad as worth distributing and your costs drop; when they swipe, distribution throttles and CPMs climb. A weak hook doesn't lose you one viewer — it taxes every impression after.

Five hook formulas that work

• The pattern interrupt. Open with motion, an odd object, or framing that doesn't look like an ad. The feed trains thumbs to swipe at anything polished; looking different buys you a second.
• The bold claim. “This is why your ads don't convert.” Plant a stake in the first second. Controversy and confidence both out-perform politeness.
• The direct question. “Still paying to test ads the slow way?” A question the target audience feels creates an open loop they want closed.
• The mid-action start. Start in the middle of the demo, the reveal, the mess. Context can come later; momentum can't.
• The result first. Show the after, then explain. Transformation in second one earns the next ten seconds of how.

The mistakes that kill hooks

The most common hook killer is the slow open: logo animation, brand intro, establishing shot. The second is front-loading context — explaining who you are before showing why anyone should care. The third is polish: footage that reads as "ad" in the first frame triggers the learned swipe reflex. Save the brand for the end; viewers reward ads that entertain first and sell second.

Test the hook before you post

Writing three hook variants takes an hour. Knowing which one holds attention used to take a paid campaign. Now you can upload each cut to PreTestAds and compare Hook Strength — predicted viewer engagement in the first 3 seconds — before spending anything. Pick the strongest hook, check where attention drops later in the ad, fix it, then launch. See TikTok ad testing for the full workflow, or how the scoring works.
