Understanding Content Distribution
Instagram uses separate algorithms for Feed, Stories, Reels, and Explore. In 2026, the algorithm has evolved to prioritize original content over reposted feeds. Let's explore how the Reels algorithm distributes videos:
Initial Cohort Testing
When you publish a Reel, it is first shown to a small test audience of your followers and a few non-followers. If this group interacts with it (likes, comments, shares, watch time), the Reel is pushed to a larger cohort.
Recommendations signals
The system evaluates the video transcript, metadata, and user watch history to recommend content. Niched creators perform better because the algorithm can easily identify who will enjoy their videos.
