TikTok FYP Secrets: What Actually Triggers the Algorithm
The 4 signals TikTok uses to decide which videos go viral — and how to game them ethically.
TikTok's For You Page is powered by 4 core signals: watch time, replay rate, share rate, and comment rate.
Watch time: If viewers watch 100% of your video, the algorithm shows it to 10x more people. Keep videos short (15-30s) until you're consistently hitting 90%+ retention.
Replay rate: Loop endings or unfinished ideas make people rewatch. Every replay counts as extra watch time.
Share rate: The single strongest signal. Videos that hit 5%+ shares almost always go viral. Add screenshot-worthy quotes or 'send to a friend who…' hooks.
Comment rate: Ask a question in the caption. Reply to every early comment in the first hour.
Combine these with a healthy follower base (JEYOS can help you cross the 10K threshold that unlocks LIVE) and you'll see consistent FYP appearances.
