Frequently Asked Questions
Why 3 seconds matter?
TikTok algorithm measures retention starting at second 1. If >50% drop off in first 3 seconds, your video gets demoted. Best-performing hooks end first sentence by 2s mark.
What is a pattern interrupt?
Something that disrupts expected scroll behavior: bold claim, visual shock, number, taboo statement, contrarian take. The brain pauses to process = retention.
