The Instagram algorithm in 2026 rewards three things above all: content people watch to the end, content people send to friends, and content that is original rather than reposted. Instagram has said this repeatedly through its head, Adam Mosseri, and through its creator guidance. The other big change is control: you can now reset your recommendations and steer the topics Instagram shows you.
This article covers what changed recently, how to reset the algorithm on your own account, and how to work out your best time to post. Meta also publishes a system card for Feed ranking. For the basics of how Feed, Stories, Reels and Explore each rank content, see our earlier guide to Instagram ranking signals.
Key Instagram algorithm updates for 2026
Instagram rarely announces a single "update". Instead it adjusts weights and adds tools. The shifts below are the ones that matter most for creators right now.
Sends per reach became a lead signal
Mosseri, who set out the basics in Instagram's ranking explainer, has named three signals as the most important for reaching new people: watch time, likes per reach and sends per reach. A send is when someone shares your post or reel to another person by direct message. Instagram treats it as a strong vote, because people only forward things they think a friend will value.
What to do: make content people want to pass on. Practical tips, relatable moments and useful lists earn sends far more often than polished but generic posts.
Originality beats reposting
Instagram updated its ranking to favour original creators over accounts that repost other people's work. When it detects a copy of content that already exists, it aims to show the original instead. Aggregator accounts that only repost lost much of their reach to recommendations.
What to do: film your own footage, use your own voice, and if you build on a trend, add something of your own. Avoid uploading videos that still carry another app's watermark.
Trial reels for testing with non-followers
Trial reels let professional accounts show a reel to non-followers first. If it performs well, you can share it to your followers afterwards. This lets you test new formats without risking a weak post in front of your main audience.
What to do: use trial reels for experiments, such as a new hook style or a new topic, and keep your proven formats for regular posts.
Longer reels and a taller grid
Reels can now be up to three minutes long, and profile grids show taller, portrait thumbnails. Longer does not mean better: watch time is measured as a share of length, so a 30-second reel that people finish usually beats a three-minute reel they abandon.
Instagram algorithm reset: how to start your feed fresh
If your Explore page and Reels tab are full of things you no longer care about, you can reset them.
- Go to Settings → Content preferences.
- Tap Reset suggested content.
- Confirm. Instagram will clear the history it uses for recommendations and rebuild it from new activity.
A reset does not change who you follow, and it does not affect your own posts or reach. After resetting, Instagram may suggest unfollowing accounts you rarely interact with, which you can skip.
To keep the new feed tidy, use Not interested on any suggested post you dislike. Tap the three dots on the post, choose Not interested, and Instagram will show fewer similar posts.
Instagram algorithm topics list: steering what you see
Instagram has been rolling out controls that show the topics it thinks you are interested in, and let you add or remove topics directly. Where available, open the Reels tab and look for the topic control in the top corner, or check Content preferences in Settings.
For creators, topics matter in the other direction too. Instagram classifies your posts by topic and recommends them to people interested in that topic. You help it classify you correctly by:
- Staying on a small set of topics. Accounts that switch subjects every post are harder to match with an audience.
- Writing descriptive captions. Instagram reads caption text, so say what the post is about in plain words.
- Using keyword-rich text on screen. On-screen text helps both viewers and classification.
- Choosing three to five specific hashtags. Broad tags like #love tell Instagram little. Niche tags help with categorisation.
Instagram algorithm and the best time to post
There is no universal time that suits every account. The right time depends on when your own followers use the app, which varies by country, age group and niche.
To find yours:
- Switch to a free professional account if you have not already.
- Open Insights → Total followers and scroll to Most active times.
- Note the days and hours with the highest activity.
Post shortly before that peak, so the post is ready when your followers arrive. The first hour matters because early engagement helps Instagram decide whether to show the post to more people.
A simple test
For four weeks, post at two different times, for example morning and evening, keeping content quality similar. Compare reach and interactions in Insights. The better slot is your posting time, at least until your audience changes.
The Instagram algorithm for reels
Reels are where most new reach comes from, and their ranking leans heavily on behaviour from people who do not follow you yet.
- Hook in the first two seconds. If people scroll past immediately, Instagram stops showing the reel to new viewers.
- Aim for completion. Cut slow intros and repeated points. A reel people rewatch counts even better.
- Use audio deliberately. Trending audio can help discovery, and original audio can become a trend that credits you.
- Add captions or on-screen text. Many people watch without sound.

Early engagement and where to start
Because early signals shape distribution, some creators give an important post an initial lift. If you do, keep it in proportion to your usual numbers and pair it with content that earns real sends and saves. Our Instagram likes and Instagram views services deliver gradually and need only the post link.
The bigger lesson from 2026 is that the algorithm follows people's behaviour. Make posts people finish, share and come back to, and the ranking systems tend to follow.
