Why hooks are 80% of the video
On TikTok, the first second decides everything. If you don't earn the next 1.5s, the algorithm assumes your video is filler and chokes distribution.
The 1.2-second window
TikTok measures 'completion velocity' — how quickly users decide to keep watching vs. swipe. If your average watch time on the first 2 seconds is under 70%, your video is dead before it had a chance.
Hooks aren't clickbait. A hook is a contract: it promises a specific payoff and your video must deliver it within the next 15 seconds.
The 3 hook layers
1. VISUAL hook — what they see in frame 1 (movement, contrast, faces, scale).
2. AUDIO hook — the first 3 words or sound effect that interrupts the autopilot scroll.
3. TEXT hook — on-screen overlay that creates a curiosity gap or stakes.
You need at least 2 of 3 firing simultaneously. Top creators stack all 3.
Examples in the wild
Alex Hormozi opens with a close-up zoom + bold caption like 'Most people will be broke forever' — visual + text firing in frame 1.
Khaby Lame's silent stitches lead with a confused face (visual) and an absurd setup clip (audio) — no words needed.
MrBeast cold-opens with the stake on screen: '$10,000 if he can finish this maze' — text + visual + voice in the first second.
Key takeaways
- →If retention at 0–2s is below 70%, rewrite the hook — do not post.
- →Stack visual + audio + text. Never rely on a single channel.
- →A hook is a promise. The next 15s must pay it off.
