How the Instagram Algorithm Works in 2026 (Feed, Reels, Explore)

Instagram runs four different algorithms, not one. What Feed, Reels, Stories, and Explore each rank on, why sends beat likes, and the repost rule that can remove you from recommendations.

Social0 is a multi-platform social media scheduler for creators, founders, and AI agents. Compose once and publish or schedule to X (Twitter), LinkedIn, Instagram, TikTok, YouTube, Facebook Pages, Threads, Bluesky, and Pinterest from one dashboard - or automate the same pipeline with MCP, the REST API, and the social0 CLI. Start on the free plan; no credit card required.
