The Cognitive Science of the 3-Second FYP Hook
TikTok's recommendation engine weighs the 3-second completion rate higher than any other single metric. If a video loses more than 65% of viewers before second 3, the video is removed from general FYP distribution.
Hooks succeed not by being clickbait, but by presenting an unresolved cognitive tension. The viewer's brain must subconsciously feel: “If I swipe away now, I will miss critical information that affects my life.”
Frequently Asked Questions (FAQ)
How many words should a TikTok hook be?
Between 8 and 16 words. At standard conversational pacing (160 WPM), 10 words take exactly 2.5 seconds to speak—leaving 0.5s of audio breath buffer.
Should I say 'Hi guys' at the start?
Never! Saying 'Hi guys', 'Welcome back', or introducing your name wastes the 1.5 seconds when the viewer is deciding whether to swipe. Start mid-action.
