Platform metrics
Completion rate
The percentage of viewers who watch a video to the end — the strongest per-viewer quality signal for short-form content.
How INFLU measures it
Computed against video length; high completion on a 30-second Reel is worth more than the same rate on a 5-second clip.

Cumulative seconds viewers spent on a video — the ranking input Instagram’s recommendation system optimises hardest for.
Plays
Video start count — Instagram’s headline Reels metric. A play is a start, not a finish, so it overstates real viewing.
Decay
How quickly a post’s engagement falls off after publishing — the half-life that separates evergreen content from a one-day spike.
