How does the TikTok algorithm work in 2026?
TikTok’s For You feed ranks videos mainly on watch time and completion rate, rewatches, shares, and comments — not follower count. Strong hooks and high completion let small accounts go viral.
TikTok's For You Page (FYP) is the most follower-agnostic algorithm in social — a brand-new account can outperform a large one on a single great video.
# The core signals
- Completion rate + watch time — finishing the video (and re-watching) is everything. Short videos that loop do well.
- Shares — sending to friends or off-platform.
- Comments + replies — especially fast early engagement.
- Re-watches — a strong quality signal TikTok leans on heavily.
# What this means
- The first 1–2 seconds decide everything. A weak hook = people swipe = the video dies.
- Keep it tight. Shorter videos with high completion usually beat long ones that lose people.
- Give a reason to rewatch or comment — a question, a twist, a detail people replay.
- Followers barely matter for reach — each video is judged fresh, so consistency + hooks compound.
TikTok also runs higher engagement-rate norms than Instagram, so judge performance against TikTok-specific bands.

Far less than on other platforms. The For You feed judges each video on watch time, completion, and shares, so small accounts can reach millions.
