Average View Duration

Average View Duration (AVD) is a YouTube analytics metric that measures the mean amount of time viewers spend watching a video before leaving. It is calculated by dividing total watch time by total number of views. AVD is one of the most important metrics for understanding content quality and pacing — a higher AVD relative to the video's total length indicates stronger viewer engagement. YouTube's algorithm uses AVD as a key signal for recommending content. Creators can improve AVD by strengthening their video intros, maintaining consistent pacing, and delivering on the promise made in the thumbnail and title.
