TikTok's algorithm is built around one core question: will this video keep someone watching?
The signals that matter most:
- Completion rate — videos people watch all the way through (or loop) get pushed harder than videos with high but shallow view counts.
- Early engagement velocity — likes, comments, and shares in the first 30-60 minutes after posting strongly influence whether TikTok tests your video to a wider audience.
- Re-watches and shares to direct messages — these are weighted heavily because they signal content worth spreading.
Practically, this means: keep videos tight (under 15-20 seconds often performs best for completion rate), hook viewers in the first 2 seconds, and post when your existing audience is most active so early engagement comes in fast.
A small like or view boost right after posting can help a video clear that crucial early engagement threshold, giving the algorithm more confidence to test it further — but it works best on content that's already well-edited, not as a substitute for it.
