TikTok's 2026 algorithm decoded — what we learned from 2M+ campaigns

What TikTok actually measures

Four signals matter:

1. **Watch-through rate** — keep them past 80%.

2. **Replay rate** — make them watch twice.

3. **Share velocity** — first 30 mins matter most.

4. **Comment-to-like ratio** — > 5% = winning.
