# How the Instagram algorithm works in 2026 > Instagram ranks posts by predicted response, originality & recency, per Adam Mosseri. Here is what that means for how & when you post. - Published: 2026-09-30 - Last updated: 2026-09-30 - Author: Sanju (Founder & CEO @ DunSocial) - Topics: instagram, tips --- Instagram ranks each post by predicting how a given person will respond to it: whether they will watch it, share it with a friend, or engage with it. Originality, recency, & topic relevance shape that prediction, not your follower count alone. That is the picture Instagram head Adam Mosseri laid out in a video series in September 2026. Here is what it means for the way you post. ## Instagram ranks content, it does not just sort by time Mosseri explained that without ranking, feeds would be overrun by the accounts that post the most, & brands post far more than creators or people. Ranking exists so people see the most relevant content in the time they spend in the app. The ranking is based on predictions of how a user will respond, including whether they will watch a post or share it with a friend. Recency matters a lot too, which is why the feed is roughly in chronological order. ## Four principles that steer the algorithm Mosseri named four principles behind where the algorithm is heading: - **Originality.** Original content, & content from the original creator, gets precedence over reposts. - **Recency.** When you post matters for how much exposure a post gets. - **Breaking content.** Public posts from small creators are shown to people who do not follow them yet, so Instagram can learn how people respond & boost new creators. - **Model size.** Larger AI models take more factors into account across a wider range of posts. ## Focus on engagement rate, not raw views For reach, Mosseri's advice to creators was to focus on engagement rates rather than total views or likes. A post that a small audience genuinely responds to is a stronger signal than one that collects passive views. He also said to experiment, because trends change & what works one week may not the next. Trial Reels are one way to test a new approach. ## Keep your topics clear Instagram now lets people adjust which topics they want more or less of in their Reels feed with a control called Your Algorithm. Commentary from agencies reads this as topic clarity mattering more, so accounts that stick to two or three consistent themes are easier for Instagram to place. Treat that as a reasonable working assumption, not a confirmed ranking rule. Instagram has not published weights. ## Post original content on a steady rhythm Reposting other people's content works against the originality principle. Recency & the small-creator test both favor accounts that post consistently, in their own voice, when their audience is around. Mosseri also acknowledged that creators try to post as much as they can to increase their chances of a hit, while managing the time they have to avoid burnout. A batched schedule solves both. ## Schedule Instagram posts for the times your audience is online DunSocial [schedules directly to Instagram](/blog/best-social-media-scheduler-for-instagram), Reels & carousels included, from the same calendar as your other accounts.

It predicts how each person will respond to a post, such as whether they will watch it or share it with a friend. Recency & originality also weigh heavily, according to Adam Mosseri. ### Does posting more often help Instagram reach? Not on its own. Mosseri said ranking exists partly because accounts that post the most would otherwise dominate feeds. Focus on engagement rate & original content rather than volume. ### Does Instagram favor original content? Yes. Originality is one of the four principles Mosseri named: Instagram tries to give precedence to content from the original creator over reposts. ### Do Trial Reels help? Yes, as a testing tool. Mosseri suggested Trial Reels as a way to experiment with different content, since what resonates changes week to week. ### Can I review an Instagram post before it goes live? Yes. Every AI-assisted draft in DunSocial waits for your confirmation before it schedules or publishes. ## Sources - [Instagram chief shares algorithm insights and posting tips (Yahoo Tech)](https://tech.yahoo.com/social-media/articles/instagram-chief-shares-algorithm-insights-200528354.html): Mosseri's ranking explanation & four principles - [What Instagram's algorithm update means for your business (Hydra Creative)](https://www.hydracreative.com/insights/what-instagrams-algorithm-update-means-for-your-business): Your Algorithm & topic clarity --- ## About this document This is the Markdown representation of https://www.dunsocial.com/blog/instagram-algorithm-2026-how-reach-works.
