Most hook advice out there is recycled guesswork, so I stopped guessing and pulled the numbers. I took over 100 TikTok posts across 15 niches, most from creators who have something to sell (an app, a product, a service). For each one I logged the hook, the angle it used, what the post was promoting, and the real engagement and view counts. The full dataset is public, I'll drop it in the comments so you can verify everything yourself.

Quick note: engagement rate is calculated as (likes + comments + shares + saves) / views.

Four hook structures actually sold. Here they are, ranked best to worst.

1. "How to + a specific, emotional pain" (the engagement king)

The format: "how to [fix a feeling the viewer already has"

Strongest structure in the whole set. Median engagement above 20%, against roughly 11% for everything else. It sounds boring and it isn't, because it names a feeling the viewer is already sitting in.

"How to stop feeling like you're wasting your life" (437k views, 26% engagement)
"How to find your purpose after losing it" (537k views, 29% engagement)
"How to rebuild your social confidence" (444k views, 19% engagement)
"How to be disgustingly overeducated" (13k views, 24% engagement)

What they were selling: Only one creator promoted a product here, an AI communication coach app. Use this when you want saves and followers, because it builds the audience you sell to later.

2. "A number + a real payoff" (the all-rounder that actually sells)

The format: "[number] [things/habits/lessons] that [specific reward]"

The one structure that sold and engaged at the same time, around 19%. The number makes it feel doable, the payoff is something people want, and the post hands over real value before it asks for anything.

"5 uncomfortable things to do alone to build extreme confidence" (284k views, 23% engagement)
"5 things I learned that made my 17 to 25 less scary" (114k views, 22% engagement)
"10/10 habits to get dangerously over-educated" (35k views, 19% engagement)
"5 hobbies with high biological ROI" (1.6M views, 15% engagement)

The payoff has to be real. "5 things I wish I knew as a beginner" (124k views, 8% engagement) did much worse.

What they were selling: a self-improvement app, a workout tracking app, a learning app, and one creator funneled viewers to his Instagram. Use this when you want to sell and keep engagement at the same time.

3. "An open question" (the reach machine)

The format: "why/what/how [open question]?"

Question hooks pulled the biggest reach of any structure, around 1.3M median views, far above the 576k median for the whole set. The catch is engagement, which runs below average, under 11%. Lots of eyes, fewer saves.

"Why is Spanish so hard??"
"What camera did you use?" (2.1M views, 11% engagement)
"Since when does Instagram have this update??" (1.3M views, 7% engagement)

What they were selling: all three were app promos, a language-learning app, a photo-editing app, and a follower-tracking app. Use this when the goal is reach and getting a product in front of a big cold audience, not saves.

4. "A curiosity tease" (the virality play)

The format: "Wait, [X] can do what??", "___, what's the catch?"

A pure tease can still go huge. These hit millions of views. The problem is that more than 80% of all hooks now use some kind of curiosity gap, so the tease by itself no longer separates a winner from a flop. Without a feeling underneath it, engagement stays around or below average.

"Wait is this fr right now?" (3.4M views, 7% engagement)
"I'm sorry Claude can do what?" (902k views, 7% engagement)
"He seems kind of too perfect, what's the catch?" (3.1M views, 12% engagement)

What they were selling: a fact-checker app, an AI coding tool, and a habit-tracking app, all riding on top of the tease. Use this for raw reach and shareability, and add an emotional core if you want the saves too.

Curiosity gets people to stop. The feeling or the value underneath is what earns the save. And the save is the thing you sell to later.
