# Watch time

> The total time people spend watching your videos — a core ranking input across platforms.

Watch time is the aggregate duration viewers spend on your content. Where retention is a per-video percentage, watch time is the cumulative total, and platforms treat it as a strong proxy for value: more total attention earned means more distribution.

Posting more clips from each long video multiplies watch time without making more source content — the core idea behind repurposing. Ten sharp 30-second clips can out-earn a single long upload in total watch time because each one is its own entry point.
