Quick answer: There isn’t one Instagram algorithm. Feed, Stories, Explore and Reels each rank posts by predicting what you’ll do: watch, like, share, save or tap through. In 2026, Instagram’s head Adam Mosseri says originality, recency and sends to friends matter most, and new posts from smaller accounts get shown to some non-followers as a test.
That means there’s no secret hashtag count or magic posting time. Instagram looks at thousands of signals and makes a guess about each post for each person. You can’t control the guess, but you can give it better material, and as a viewer you can now steer it more directly than before.
This guide pulls together what Instagram has officially said about ranking, plus what Mosseri shared in September 2026. More guides like this live in our social media section.
How does the Instagram algorithm decide what you see?
Instagram’s own ranking explainer says each part of the app uses its own system, because people use each part differently. In every case, Instagram first gathers the posts you could see, then scores them on how likely you are to interact with them.
In a September 2026 video series, reported by Social Media Today, Mosseri explained that without ranking, your feed would be dominated by whoever posts the most. Ranking predicts “how users will respond to a post, including whether they’re likely to watch it, share it with a friend, etc.”
What matters in Feed, Stories, Explore and Reels?
| Section | Mostly shows | Key signals Instagram lists |
|---|---|---|
| Feed | Accounts you follow, plus suggestions | Your activity, post popularity and timing, your history with the poster |
| Stories | Close connections | How often you view their Stories, likes and DMs, how close you are |
| Explore | Accounts you don’t follow | Post popularity, your Explore history, likes, saves and shares |
| Reels | Entertainment, often from new creators | Reshares, watching to the end, likes, visits to the audio page |
Two patterns stand out. Stories favour people you already talk to, so DMs and replies help. Reels and Explore are about discovery, so shares and full watches carry a lot of weight.
What did Adam Mosseri say about the algorithm in 2026?
According to Social Media Today, Mosseri highlighted four principles:
- Originality. Instagram favours the original creator over accounts that repost other people’s content.
- Recency. When you post matters, and feeds are kept “roughly in chronological order” among the posts Instagram picks.
- Testing small creators. Posts from smaller public accounts are shown to some non-followers to see how they respond. A good response can push a post wider.
- Bigger models. The AI systems behind ranking now consider more signals across more types of content.
He also suggested creators watch engagement rates rather than raw views or likes, keep experimenting because trends shift quickly, and post often enough to get chances at a hit without burning out.
How can creators and small businesses get more reach?
Based on Instagram’s guidance, these are the habits that line up with how ranking works:
- Make it yours. Original photos and videos beat reposted clips. If you sell products, shoot your own items rather than reusing supplier images.
- Earn shares, not just likes. Content people send to a friend, such as a useful tip, a relatable joke or a “this is you” moment, scores well in Reels and Explore.
- Hook from the first second. Instagram’s Reels guide stresses strong openings and suggests 15 to 60 seconds as the sweet spot for tutorials and most formats, with longer Reels up to three minutes for walkthroughs.
- Use text overlays and captions. Overlays highlight key moments, while captions make your audio readable for people watching on mute.
- Try trial Reels. Mosseri recommends them for testing new ideas. Per TechCrunch, trial Reels are shown only to non-followers, and after 24 hours you can see how they did and choose whether to publish them to your profile. They need a professional account.
- Talk to your audience. Replies, DMs and Story stickers build the closeness signals that help in Stories and Feed.
- Check Account Status. Instagram’s ranking page says you can see there whether your account is eligible to be recommended to non-followers. A policy problem can quietly limit your reach.
What doesn’t help
Buying followers, engagement pods and mass-reposting viral clips all work against the signals above. Fake followers don’t watch or share, which drags down your engagement rate, and reposted content loses out to the original.
How do you reset or control your own Instagram feed?
As a viewer, you have more control than many people realise:
- Use “Your Algorithm” in Reels. Launched in December 2025, it shows the topics Instagram thinks you like and lets you add topics, remove them or see less of them. Search Engine Land reported it started in the US with a global English rollout planned, so it may not have reached every account.
- Tap “Not interested” on posts you don’t want more of.
- Add accounts to Favorites so their posts rank higher in your feed, and use Close Friends for Stories you share.
- Reset your recommendations if your suggestions have gone stale. Engadget reported in November 2024 that the option sits in settings under content preferences and clears suggestions across Feed, Reels and Explore. It doesn’t delete your data or change ad personalisation.
Is the algorithm the reason my reach dropped?
Sometimes, but rarely in a mysterious way. Before blaming a “shadowban,” check Account Status for violations, look at whether your recent posts were reposts or very similar to each other, and compare engagement rate rather than total views. A sudden drop can also follow a hacked account or spam-like behaviour. If you’ve lost access entirely, our guide on how to recover a hacked Instagram account walks through the official steps.
Frequently asked questions
What is the best time to post on Instagram?
Instagram hasn’t published a universal best time. Mosseri says recency matters, so post when your own followers are active. Your Insights panel in a professional account shows when that is.
Do hashtags still matter on Instagram?
Hashtags aren’t among the main signals Instagram lists in its ranking explainer. They can help describe a post, but shares, saves, watch time and originality matter far more for reach.
Does Instagram show my posts to non-followers?
Yes, especially through Reels and Explore. Mosseri says posts from smaller public creators are tested with some non-followers, and good responses can lead to wider distribution.
Can I reset my Instagram algorithm?
Yes. Instagram has a reset option for recommendations in its content preferences settings, which clears suggestions in Feed, Reels and Explore. You can also steer things with “Your Algorithm” in Reels where available, “Not interested” and Favorites.
