Save posts describes the action of a viewer bookmarking a video, Short, or community post, usually through the "Save to playlist" or "Watch later" buttons on YouTube, or the save icon on Shorts. Saves are a strong satisfaction signal: they tell the platform the viewer expects to come back to the content, which lines up with high value and rewatch potential. Videos with strong save rates often earn better ranking in suggested feeds because saves correlate with future watch time and returning-viewer behavior.
