Average view duration (AVD)
The average number of seconds a viewer spends inside a video before leaving.
Average view duration (AVD) is the mean watch time per impression, measured in seconds or minutes:seconds. It is one of two metrics YouTube uses to decide how to distribute a video, the other being click-through rate.
AVD is an absolute number, not a percentage. A 90 second video and a 9 minute video can have wildly different AVPs (percentages) but identical AVDs. The algorithm weighs absolute watch time heavily, which is why longer videos with strong retention often outperform short ones in the recommended feed.
AVD interacts with video length: doubling video length without dropping retention almost always pushes the video harder, because total watch time per impression doubles.

Why it matters
AVD is the metric YouTube optimizes for. Two videos with the same CTR but different AVDs will be distributed very differently. Pushing AVD up by 30 seconds on a 5 minute video can double total reach over the video's lifetime.
How to improve it
- 01Cut every section that does not advance the curiosity loop. Pacing beats production.
- 02Open new loops before closing old ones to keep AVD compounding.
- 03End cards that lead into a follow-up video extend session AVD across multiple uploads.
