YouTube watch time

Watch time is the total minutes viewers spend watching your videos. YouTube uses it as the primary ranking input — more than likes, more than comments, more than subscriber count.

Two derived metrics matter most:

• Average view duration: the mean seconds watched per view.
• Audience retention graph: the percentage of viewers still watching at each timestamp.

A strong retention graph keeps a flat line for the first 30 seconds (no hook drop-off) and retains at least 40% by mid-video. High watch time unlocks suggested-video placement, which is the main discovery surface for established channels. For monetization, 4,000 public watch-hours in the last 12 months is the gate for the Partner Program, alongside 1,000 subscribers.
