Understanding TikTok's Algorithm in 2025
Algorithm Ranking Factors
Primary Signals (High Impact):
- User Interactions: Likes, shares, comments, follows
- Video Information: Captions, sounds, hashtags, effects
- Device/Account Settings: Language, location, device type
- Completion Rate: Percentage of viewers who watch full video
- Re-watch Rate: Users watching video multiple times
Secondary Signals (Medium Impact):
- Profile Engagement: Account followers and following

- Secondary Test (1-6 hours): 1K-10K views
- Viral Push (6-24 hours): 100K+ views
- Peak Distribution (24-72 hours): Maximum reach
- Decay Phase (3-7 days): Gradual decline
