Audience retention curve
A chart showing what percentage of viewers are still watching a video at each point in its runtime.
An audience retention curve is a chart, usually plotted with playback position on one axis and the percentage of viewers still watching on the other, that shows exactly where in a video people stop watching.
It is built by measuring, at each point in a video's runtime, what share of viewers who started the video are still present. This differs from a single-number metric like watch time or overall completion rate, because it locates the specific moments, a slow intro, an ad break, a weak segment, that cause the sharpest drop-offs, rather than only reporting an average.
Video creators and publishers use retention curves to diagnose pacing problems, decide where to place ad breaks with the least disruption, and identify the segments viewers rewatch, which often signal the most valuable content. Combined with content engagement data, the curve helps prioritize edits for future videos. A common misreading is comparing raw retention curves across videos of very different lengths without normalizing for runtime, since longer videos naturally show steeper average decay.
