How the Instagram Algorithm Works in 2026
Instagram doesn't have one algorithm. Feed, Stories, Explore and Reels each rank differently. Here's how they work in 2026, including originality, sends and the new 'Your Algorithm' controls.
Key takeaways
- Instagram uses different ranking systems for Feed, Stories, Explore and Reels.
- For reaching new people, Instagram has highlighted watch time, likes per reach and sends per reach as top signals.
- Original content is prioritised over reposts, and people can now tune topics with 'Your Algorithm'.
- Negative signals (quick skips, 'Not interested', hides) reduce distribution.
“The Instagram algorithm” is really several systems. Instagram’s head, Adam Mosseri, has repeatedly explained that each part of the app (Feed, Stories, Explore and Reels) is ranked differently, because people use each one differently. Here’s how they work in 2026.
Feed
The Feed shows posts from accounts you follow plus suggested posts. Signals include:
- Your activity: which posts you like, comment on, save and share
- Your relationship with the poster: do you message, comment or view their profile often?
- Post information: how popular it is and how quickly people engage
- Information about the poster: how often people interact with them
Stories
Stories are mostly from accounts you follow, ranked by closeness (DMs, Story replies, profile views) and viewing history. In 2026 Instagram removed the originality penalty for reposted content in Stories, according to industry reporting.
Explore
Explore recommends content from accounts you don’t follow, based on what you’ve engaged with before and what similar people engage with. Popularity matters more here.
Reels
Reels are designed largely for discovery. For reaching people who don’t follow you, Instagram has highlighted three signals:
- Watch time: how long people watch
- Likes per reach: the share of viewers who like it
- Sends per reach: the share of viewers who send it to friends via DM, the strongest signal for reaching new audiences

Negative signals
Instagram also listens to what people don’t want: quick skips, “Not interested”, hiding posts, muting and unfollowing all reduce distribution. Misleading hooks and repetitive content hurt.
What brands should do
- Make original Reels around a few clear topics.
- Hook fast and deliver, so watch time is strong and skips are low.
- Create content worth sending, such as useful tips, relatable moments and things people want to show a friend.
- Build relationships: reply to comments and DMs, use Stories to talk with followers.
- Test with Trial Reels, then share winners.
- Measure sends, saves and non-follower reach in Insights.
