Once you have this inventory on hand, your artificial intelligence tools review some key user-determined signals. These “are pieces of information that we review from each post, every time you go to the news section … there are about 10,000 personalized signals,” explains Jason Hirsch, head of legitimacy and integrity policies at Facebook. Among the most important signals that the platform takes into account are who posted it, what type of posting it is and how popular the post is both on Facebook in general and in your circle, in particular. Other important signals but less than the previous ones are when it was posted or even the device or the quality of the internet signal that you have at the moment, for example, if you are in a place with little signal, Facebook will decide not to show you a video.
Since the signals are given, a third component to analyze are the predictions, that is, Facebook evaluates how likely it is that you will interact with a person either because they are your family member or friend, how likely it is that a post will catch your attention or even that you hide it. For this, the platform can make predictions through direct feedback that you have given them when answering a survey on specific content or predictions based on integrity, where the decision is made not to show content or reduce its distribution because it represents a problematic behavior. or low quality.
The fourth element is the rating, which is decided by each post in your news section. To do this, Facebook takes into account positive attributes such as the relevance and meaning of the post, and makes a balance (subtraction) with the negative attributes (such as clickbait or content that you are going to hide). The result is the final rating on which Facebook decides whether or not to show the content, depending on the rating your other content has in the feed. So far we cannot determine what would be the highest rating for a post within the platform.
These elements then answer the question about why some of your posts do not appear to other people, as well as why you see more and more posts from a specific person or page.
Facebook ensures that there are no two similar feeds, because everything it does is personalized, in addition, the objective of doing so is to ensure that people have a more efficient experience, with the possibility of finding the most valuable content more easily.
