๐ก Did You Know?
๐ How It Works
TikTok's algorithm tests content in stages. The 3-second rule filters out weak hooks. The 8-second gate ensures viewers aren't dropping after the hook. Completion rate is the apex metric โ high completion signals valuable content worthy of viral distribution.
The Three Gates
3-Second Gate: Fail here = no distribution. 8-Second Gate: Retention must hold โฅ30% of 3s or tier limited. Completion Apex: 80%+ Viral, 50-79% Strong/Moderate, 30-49% Limited, <30% Fail.
๐ฏ Expert Tips
๐ก Front-Load the Hook
First frame + first 3 seconds. No intro, no "Hey guys" โ jump straight into value.
๐ก Cut the Fat
If completion <50%, shorten to 7-15 sec. Every second past the payoff hurts completion.
๐ก SEO Keywords
Use 2-3 keywords in caption + audio. Search tail can triple evergreen revenue.
๐ก Test & Iterate
Run A/B hooks. Track 3s vs 8s retention โ if big drop, hook is strong but payoff weak.

โ FAQ
What is the 3-second rule?
TikTok tests if viewers stay 3 seconds. If fewer than 70% do, the algorithm stops distribution โ your video "fails" the first gate.
Why does 8-second retention matter?
It catches "hook-only" content. If retention drops below 30% of 3s by 8s, algo assumes the payoff is weak.
What completion rate is viral?
80%+ completion triggers viral distribution. 50-79% is Strong/Moderate. Below 30% is Fail.
What is search tail revenue?
Views from search/discovery months after posting. SEO-optimized content earns 30-50% from search tail.
How do I improve completion rate?
Shorten the video, cut intros, front-load value. If completion <50%, aim for 7-15 sec.
Does niche affect RPM?
Yes. Finance/tech see $1-2 RPM; entertainment often $0.10-0.30. Completion + niche = compound revenue.
Should I use SEO keywords?
Yes for evergreen content. Keywords in caption + audio drive search discovery and search tail revenue.
What is Neural SEO Score?
Combined score of keyword usage, search volume, and completion. Higher = more discoverable and revenue from search.
