Instagram recommendation algorithm

Topic

The Instagram recommendation algorithm is a complex suite of machine learning models and ranking systems used by Meta to personalize content delivery across the Instagram platform. Rather than relying on a single algorithm, it utilizes distinct ranking processes tailored for different features, including the Feed, Stories, Explore, Reels, and Search. The system evaluates thousands of signals—such as user activity, post popularity, and interaction history—to predict and prioritize content most likely to engage each individual user.
