Adam Mosseri, the first person on Instagram, decided to explain to users how this social network works, so those who are interested in it get answers to their questions about why certain content is shown to them more frequently than others.
He explained that it depends on a large number of signals, processes and algorithms to provide each user with a unique personalized experience.
He said that the first thing to look at is the popularity of the post, that is, how many people like it. There is also important information about the content of the post: when it was published, where it was published, and the length of the post (if it is a video).
The second signal shows the importance of the person posting the content to you. It looks at information about how many interactions you have recently with that person. Interacting with specific people shows that you are interested in their posts.
Your activities are also important. It keeps track of how many posts you usually like, and the posts you like and comment on more often.
According to Mosseri, based on these signals, Instagram makes assumptions about how interested you are in a particular post and whether you will react to it. In short, the more likely you are to like, comment, save, or share a post, the sooner it will be shown to you.
