Why the first 3 seconds decide everything

On TikTok, the For You algorithm watches how quickly people swipe away. If your opening line doesn't promise a payoff, viewers scroll before your video gets a chance — and weak retention tells the algorithm not to push it further. A strong hook buys the attention you need for the rest of the video to land.

What makes a hook work

• A clear promise — tell viewers exactly what they'll get if they stay.
• An open loop — raise a question the payoff will answer.
• Specifics over vagueness — numbers, names, and concrete details feel more real.
• Tension or surprise — challenge an assumption or tease an unexpected result.

Common hook mistakes to avoid

• Long intros ("Hey guys, welcome back…") — get to the point immediately.
• Burying the payoff — put the most interesting moment first, not last.
• Over-promising — a hook the video can't deliver on hurts both retention and trust.
