The Facebook-owned company assembled a group of reporters at its under-construction new San Francisco office to take the lid off the Instagram feed ranking algorithm.
Instagram relies on machine learning based on your past behavior to create a unique feed for everyone. Even if you follow the exact same accounts as someone else, you’ll get a personalized feed based on how you interact with those accounts.
Three main factors determine what you see in your Instagram feed:
1. Interest: How much Instagram predicts you’ll care about a post, with higher ranking for what matters to you, determined by past behavior on similar content and potentially machine vision analyzing the actual content of the post.
2. Recency: How recently the post was shared, with prioritization for timely posts over weeks-old ones.
3. Relationship: How close you are to the person who shared it, with higher ranking for people you’ve interacted with a lot in the past on Instagram, such as by commenting on their posts or being tagged together in photos.
