Instagram told how their Home Feed Ranking System is set up.

The announcement was made by the developer of the social network algorithm Amog Mahapatra. So we share with you the main theses.

The Instagram feed is divided into two parts, where the system works based on different assumptions. In the first feed, the machine sorts based on who you subscribe to. Therefore, those who subscribe to anybody, greatly spoil the quality of life on Instagram.

In the second tape, the system, based on your saved posts and reposts, tries to determine your most passionate interest: for example, architecture. The machine searches for accounts on this topic and slips you such posts until you like them and comment.

Hence the conclusion: a blogger who cannot understand what she loves more – marketing, raising a child or embroidery – will always lose in the system of those who have chosen a single topic.

The main selection factors for the algorithm in both parts of the tape are: involvement (number of likes and comments), relevance (you like cats – you are shown cat accounts) and freshness (the newer, the better). If the first can still be wound, the second two are impossible.

Another important signal for the machine: whether the account is growing or unsubscribing from it. Such people, who invests in growth benefits on all fronts, including the coverage of the post by older subscribers.

Another important factor is the so-called “Content quality”. This includes high quality pictures / videos, their originality (copies receive less coverage) and no complaints.

The advantage of the first contact works in the feed: if you subscribe to someone, finding in the recommendations, you will first see many of his posts, much more than those to whom you have subscribed for a long time.

What does the algorithm do if there is nothing to rely on – when a person just came to Instagram? He slips the most popular accounts until a person likes. From this cursing system builds your interests – first rudely, and then more accurately.

Have you noticed anything like this on your tape?
