Average View Duration
The mean amount of time viewers spend watching a video, in seconds or as a percentage of its length.
Average view duration is the typical watch time across everyone who saw the clip. As a percentage of total length it's a clean way to compare videos of different durations — a 20-second clip watched to 90% is doing better than a three-minute one watched to 30%.
Shorter, tighter clips tend to post higher percentage retention, which is part of why short-form favors brevity.

Retention (Watch Time)
How much of a video viewers actually watch — the metric short-form algorithms weight most heavily.
Read →Completion Rate
The percentage of viewers who watch a clip all the way to the end (and often loop it).
Read →Engagement Rate
The share of viewers who like, comment, share or save — signals that a clip resonated enough to act on.
Read →Virality Score
An AI prediction (often 0–100) of how likely a clip is to perform, based on hook, pacing and retention signals.
