There isn’t one algorithm. Instagram uses different systems for Feed, Stories, Reels and Explore, but they look at similar signals.
What Instagram looks at
- Your activity: what you like, save, share and watch.
- The post: how quickly people engage, how long they watch, how many save or share it.
- The creator: how often you interact with them.
For reels specifically
Watch time, rewatches and shares matter most. A reel watched to the end and sent to a friend gets pushed further.
What this means for you
- Hook people in the first second.
- Make content worth saving or sharing.
- Post consistently so Instagram learns who your audience is.
- Grow an audience that matches your niche, because their engagement trains the algorithm.
