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.
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:
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:
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.
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.
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.
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.
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.
Use Insights to find your peak follower times. Many accounts see strong engagement midday Tues–Thurs, but test and track your own data.
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.
Reply to comments, DMs, and tags thoughtfully. Interaction with other creators in your niche can also boost cross-audience reach.
Balance your content between Reels, Carousels, Single Posts, Stories, and Lives. Instagram rewards consistent activity across features.
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.
Phrases like “Comment YES if you agree” can tank your reach. Instead, ask genuine, thought-provoking questions.
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.
