Instagram Algorithm 2025: How It Works and How to Beat It

When it comes to Instagram's algorithm, many changes have been made over the years. Learn the new rules and how to create content that ranks.

Instagram started in 2010 as a simple app to share photos with friends and family. The feed was chronological, and the focus was on still images. Fast forward nearly 15 years, and the platform has transformed into a multi-feature hub with three feed views (Home, Favorites, Following), Reels, Stories, Explore, Shop, and new features like Blend and the Friends Tab in Reels.

In 2025, the Instagram algorithm has evolved again — and so must your strategy. Let’s break down how it works today and how you can make it work for your brand.

The Instagram Algorithm: 2025 Edition

Adam Mosseri, Instagram’s CEO, has repeatedly explained that “the algorithm” isn’t a single formula but a collection of algorithms tailored to different parts of the app. Here’s how these different algorithms decide what content to show you:

  • Feed & Stories → Prioritizes posts from people you interact with most, with a heavy emphasis on recent engagement and relationship closeness.

  • Reels → Prioritizes entertaining, original, high-retention videos, even from accounts you don’t follow.

  • Explore → Designed for discovery; shows trending or niche content based on your past behavior.

  • Shop → Tailored to your browsing and purchasing habits.

Key Ranking Signals in 2025

Ranking Signals refer to the data Instagram uses to feed its algorithms, so Instagram can predict which pieces of content you’re most likely to interact with. In 2025, Ranking Signals with the most weight include:

  1. Saves – Top indicator of valuable content.

  2. Shares – Especially via DMs; a strong sign that the content is worth spreading.

  3. Watch Time & Retention – Particularly important for Reels.

  4. Originality – Reposts are labeled and deprioritized.

  5. Meaningful Interactions – Comments and genuine conversations still matter, but engagement bait is penalized.

11 Tips to Beat the Instagram Algorithm in 2025

1. Prioritize Original Content

Reposted or aggregator content gets less reach. Use your own images, videos, and captions. If you must repost, add significant commentary or a unique spin.

2. Optimize for Saves and Shares

Create content worth revisiting or sharing—how-tos, checklists, relatable memes, recipes, workouts, or carousel guides. Include subtle calls-to-save or calls-to-share.

3. Nail Your Hook in Reels

The first 3 seconds determine if viewers stick around. Use movement, text overlays, or curiosity-driven hooks. The algorithm boosts videos with 70%+ average watch time.

4. Use Hashtags Strategically

Forget 30 generic hashtags—opt for 5–10 niche-specific tags. Combine high-volume and hyper-niche keywords to improve discoverability.

Run hashtag contests using a uniquely branded hashtag for a boost in visibility and engagement. Read our article How to Run a Successful UGC Hashtag Contest to learn more.

5. Leverage SEO in Captions

Instagram now scans captions, alt text, and video frames for keywords. Write naturally, but include terms your audience might search for both in-app and on Google.

6. Post When Your Audience Is Active

Use Insights to find your peak follower times. Many accounts see strong engagement midday Tues–Thurs, but test and track your own data.

7. Experiment with "Trial Reels"

If you have 1,000+ followers, Instagram tests new Reels with non-followers first. If they perform well, they get a bigger push—so make your first 3 seconds shine.

8. Engage Deeply, Not Just Quickly

Reply to comments, DMs, and tags thoughtfully. Interaction with other creators in your niche can also boost cross-audience reach.

9. Diversify Formats

Balance your content between Reels, Carousels, Single Posts, Stories, and Lives. Instagram rewards consistent activity across features.

10. Use Stories for Connection, Not Just Promotion

Stories may not directly boost feed ranking, but they build trust and keep your brand top-of-mind. Add polls, questions, and behind-the-scenes clips.

11. Avoid Engagement Bait

Phrases like “Comment YES if you agree” can tank your reach. Instead, ask genuine, thought-provoking questions.

What’s New in 2025 You Should Know

  • Blend Feature – Share your personalized Reels feed with friends for cross-exposure.

  • Friends Tab in Reels – See Reels your friends engage with; another potential discovery channel.

  • Connected vs. Unconnected Reach Metrics – Now you can see how much of your reach comes from followers vs. new audiences.

  • Child Safety Algorithm – Content with minors under adult management is restricted from potentially risky recommendations.

  • Algorithm Safety Updates – After a major 2025 glitch, Meta doubled down on content moderation in Reels.

Conclusion

Instagram is no longer just a photo-sharing app — it’s a complex ecosystem of algorithms, features, and audience behaviors. Success in 2025 comes from focusing on originality, delivering content worth saving and sharing, and leveraging every format strategically.

By understanding how each part of the app works — and how the algorithm treats different engagement signals — you can build a strategy that keeps your brand visible, relevant, and growing in the ever-crowded Instagram space.
