Ranking Factors
TikTok's #1 ranking signal. The percentage of viewers who watch a video to the end (or rewatch it) is the strongest predictor of further distribution. A 60%+ completion rate on a 15-second video typically triggers wider FYP push.
When viewers loop a video or watch multiple times, TikTok reads this as exceptional quality. Short videos (7 to 15 seconds) with seamless loops get heavily boosted.
Sharing to DMs or external platforms (WhatsApp, iMessage) is one of the strongest engagement signals — weighted significantly higher than likes.
Comments and reply-comments signal community-worthy content. Replying to your own comments within the first hour boosts overall engagement velocity.
Less weighted than completion or shares, but still a positive signal. The ratio matters more than the absolute count.
Actionable Tips
- →Hook viewers in the first 1 to 2 seconds with motion, faces, or a bold text overlay
- →Aim for 15 to 30 seconds — the sweet spot for completion rate in 2026
- →Design your videos to loop seamlessly so re-watches feel natural
- →Reply to top comments in the first hour to spike engagement velocity
- →Add captions/text overlays — 80% of TikTok is watched with sound on but text drives accessibility and retention
