Going viral on TikTok comes down to retention. The first two seconds decide everything, so open with a hook, not a hello. Pick one niche so the algorithm knows who to show you to, post consistently and make videos people watch to the end and share. Trends help but a strong hook and a clear niche matter more.
What actually drives reach
Reach follows retention, not luck. Earn the watch and the algorithm rewards you.
Hook in two seconds
Open on the payoff or the question. No slow intros.
One niche, posted often
A clear lane tells TikTok who to test you on.
Optimize for watch time
Short, tight edits that people finish beat long rambling ones.
