TikTok’s algorithm changes fast — but certain rules have stayed consistent. Here’s the simplest explanation of how TikTok decides who sees your video.
1. TikTok tests your video with a small group
Every video is shown to a small test audience (50–300 users).
If these users:
- watch for 5+ seconds
- rewatch
- like or comment
…your video moves to a bigger group.
2. Watch Time > Likes
TikTok cares more about how long people watch than how many likes you get.
3. Rewatch rate is the secret factor
Videos people replay get boosted aggressively.
4. Topic consistency helps your page
Posting random content confuses the system.
The algorithm loves “category clarity.”
5. TikTok pushes content that feels ‘native’
Natural lighting, human faces, quick cuts = success
Over-edited, commercial-looking videos = less reach
Bonus Tip: Don’t delete low-performing videos
Even a “dead” video can blow up suddenly weeks later.
Final Thought:
Understanding the algorithm doesn’t guarantee virality — but it gives you a massive advantage.
Create for humans, optimize for the system.
