"Instagram Clarifies Feed and Content Recommendations Algorithm"

Instagram's chief, Adam Mosseri, has shared an overview of how Instagram's ranking algorithms work, including the main feed, Stories, Reels, and Explore. Instagram uses different algorithms for each part of the app, tailored to how people use it. The four key factors that dictate the ranking of the main Instagram feed are activity, information about the post, information about the person who posted, and history of interacting with someone. Instagram's system ranks Stories based on viewing history, engagement history, and closeness. Reels are more influenced by entertainment, and the key ranking factors are activity, history of interacting with the person who posted, information about the reel, and information about the person who posted.
