🔑 Engagement & Retention Signals

• Average watch time / completion rate → 10/10
  If people watch till the end, the algo keeps pushing. This is the strongest signal.

• Rewatches per viewer → 10/10
  Stickiness. Tells the algo it’s replay-worthy.

• Hook retention (first 3–5 sec) → 9/10
  If people don’t swipe early, your video survives the “first filter.”

🚀 Distribution Signals

• Shares per 100 views → 8/10
  Expands audience beyond the feed.

• Save-to-view ratio (saves per 100 views) → 8/10
  Indicates long-term value. Platforms see this as a “bookmark for later,” very positive.

• Profile clicks per 100 views → 7/10
  Signals curiosity about you as a creator. Stronger for account growth than for pure video scaling, but still good.

💬 Interaction Signals

• Comments per 100 views → 5/10
  Shows depth of engagement. Important but not as predictive as watch/shares.

• Likes per 100 views → 4/10
  Baseline engagement, but too easy. Algorithms treat it as weak compared to stronger actions.

🌀 Negative Signals

• Swipe-away rate in first 3 seconds → -10/10
  Immediate killer. If too high, video dies.

• Mute / sound-off rate → -6/10
  Platforms want engaging audio-visual experience. If most mute → weak.

• Low completion with long duration → -8/10
  If your video is long but no one finishes, scaling stalls.
