Instagram Algorithm in 2026: How to Get More Reach and Engagement

Forget About One Algorithm

Instagram doesn’t have one algorithm. It has several, and each works differently. Feed, Stories, Reels, Explore page – every part of the app has its own rules.

“People tend to look for their closest friends in Stories, use Explore to discover new content and creators, and be entertained in Reels,” Mosseri explains.

That’s why a video that kills in Reels might flop in the feed. And vice versa.

What Actually Matters in the Feed

Instagram tracks thousands of signals, but five things carry the most weight:

• User engagement – what a specific person likes, shares, and saves. When a customer regularly reacts to beauty products, they’ll see more of them.
• Content performance – how many people react to a post and how quickly. Instagram counts everything from likes to whether someone taps on your profile photo.
• Information about the poster – how often people have interacted with your account in recent weeks.
• Relationship history – regular comments between accounts tell Instagram who wants to see your content.

Carousels Win

Buffer analysed over 4 million posts, and the result is clear: carousels get the highest engagement. Videos follow, then classic photos.

The reason is simple. When someone doesn’t swipe through a carousel to the end, Instagram shows it to them again later – starting from the first unseen slide. One post = multiple chances for reach.

You can upload up to 20 photos or videos in one carousel. For product photos, this makes sense – detail shots, styling, use in practice, and customer reviews.

Stories Are About Community

Don’t look for massive reach in Stories. Instagram built them for connecting with people who already follow you.

The algorithm tracks three things

• how often someone watches your Stories
• how they interact with them (DMs, reactions)
• how connected you are offline

Practical tip: Use interactive elements. Polls, questions, “add yours” stickers. The more someone taps, the higher you’ll appear in their stories tray.

And share user-generated content. When a customer tags you with your shoes, add it to Stories. It works as social proof and motivates others to tag you too.

Reels and the Power of Sharing

The Reels feed is where you can reach people who don’t follow you. And here comes the surprise.

Of all engagement types, DM sharing carries the most weight.

“Short-form video is so symbiotic with connecting people with their friends,” says Mosseri. When people share your Reel in private messages, Instagram takes it as a massive quality signal.

Optimise content so people want to share it. Not for viral reach – for conversations between friends.

Practical tips for Reels

Stay between 30-90 seconds

Instagram will show three-minute videos, but shorter ones perform better.

Add text to the first frame

Half of videos are watched without sound, so it needs to be clear what it’s about even on mute.

No TikTok or other app logos

Instagram pushes these down in the algorithm. Your own branding is fine.

Explore Page: How to Get There

Explore is a grid full of content from accounts you don’t follow. For brands, it’s a goldmine.

Instagram tracks how popular a post is here – how many reactions it gets and how quickly. Popularity counts more than in the Feed or Stories.

Example from Instagram: You like photos from a dumpling chef in San Francisco. Instagram looks at who else likes her content and what those people are interested in. If they also like a dim sum restaurant, next time in your Explore you might see a post from that restaurant.

How to get your products there

Use trending audio. Instagram tracks which tracks are taking off, and content with them has a better chance of reach.

Track what gets shared. Click View Insights below a post and see which posts are shared the most. Then create more similar content.



What Doesn’t Work

Instagram actively pushes down some things:

• Content about self-harm, violence, and eating disorders won’t show up in search
• Sexually explicit or suggestive posts end up at the bottom
• Promotion of tobacco or regulated products – also no

And watch out: hashtags no longer help reach. Instagram removed the ability to follow hashtags in December 2024 and reduced their weight in algorithms.

What works instead?

Keywords in captions and your profile. People find you through search, and Instagram uses them to understand what your content is about.

If you use hashtags, stick to 3-5 relevant ones per post. Not dozens.

Rules That Apply Everywhere

Consistency wins. Buffer analysed over 100,000 users across platforms – those who post regularly get nearly five times more engagement per post compared to those who post occasionally.

• There’s no ideal time for everyone. Instagram Insights will show you when your audience is online. Test and stick with what works.
• Create original content. Instagram wants to reward original creation, not reposts from other accounts.
• Use different formats. You can leverage one idea multiple times – turn a Reel into a carousel, share the carousel in Stories with fresh content added.
• And track data. Instagram Insights or tools like Buffer will show you what works. Then do more of that.

Bottom Line

Instagram is finally playing with open cards. No secrets, no speculation. Algorithms aren’t the enemy.

They’re set up to show people content they’re interested in. If you create relevant things and build community, the algorithms work for you. Trying to game the algorithms might work short-term. Long-term, it won’t.
