🔑 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.
