Instagram Ranking For Posts

1. Information about the post – These are signals both about how popular a post is – think how many people have liked it – and more mundane information about the content itself, like when it was posted, how long it is if it’s a video, and what location, if any, was attached to it.
2. Information about the person who posted – This helps us get a sense for how interesting the person might be to you, and includes signals like how many times people have interacted with that person in the past few weeks.
3. Your activity – This helps us understand what you might be interested in and includes signals such as how many posts you’ve liked.
4. Your history of interacting with someone – This gives us a sense of how interested you are generally in seeing posts from a particular person. An example is whether or not you comment on each other’s posts.

Reels has its own algorithm, as Instagram works to compete with TikTok. The TikTok algorithm is highly attuned to user interests, and will quickly shift to show you more of what you’re interested in as you scroll through the app, and Instagram’s developing its Reels algorithm along similar lines.

1. Your activity – We look at things like which reels you’ve liked, commented on, and engaged with recently. These signals help us to understand what content might be relevant to you.
2. Your history of interacting with the person who posted – Like in Explore, it’s likely the video was made by someone you’ve never heard of, but if you have interacted with them that gives us a sense of how interested you might be in what they shared.
3. Information about the reel – These are signals about the content within the video such as the audio track, video understanding based on pixels and whole frames, as well as popularity.
4. Information about the person who posted – We consider popularity to help find compelling content from a wide array of people and give everyone a chance to find their audience.
