Saves indicate intent: a like is cheap, but a save means "this is worth keeping." That makes save rate a quality signal that often predicts reach better than likes, because recommendation systems interpret high saves as evidence the content is valuable enough to recommend to more people.
Educational, reference, and how-to content earns the highest save rates — recipes, tutorials, checklists, and tip lists people genuinely want to find again. Creators optimize for saves by making content worth keeping and explicitly prompting it ("save this for later"), since a strong save rate can extend a post's reach well beyond its initial audience.
