What Is Instagram Algorithm? A 2025 Deep Dive
What Is Instagram Algorithm? Instagram’s algorithm isn’t a single formula—it’s a suite of AI‑driven algorithms powering your Feed, Stories, Reels, and Explore tabs. In 2025, it’s more personalized than ever. It tracks your actions (likes, comments, shares, saves, DMs, view-time), content attributes, relationships, keyword usage, recency, and even shopping signals to decide what shows up first businessinsider.com+15metricool.com+15recurpost.com+15vamp.com.
🗝️ Key Components of the 2025 Algorithm
1. AI-Driven Customization
Instagram uses machine-learning to tailor your feed based on your preferences—analyzing captions, video content, image data, and hashtags/keywords .
2. Engagement Signals
Likes are now the weakest signal.
Stronger signals include:
