Facebook: One of our News Feed values is authentic communication. We’ve heard from our community that authentic stories are the ones that resonate most — those that people consider genuine and not misleading, sensational or spammy.
When ranking News Feed we look at many signals personal to you, such as how close you are to the person or Page posting, as well as more universal signals like the overall engagement (likes, comments, shares) that a post has.
With this update, we’re adding new universal signals to determine whether a post might be authentic. To do this, we categorized Pages to identify whether or not they were posting spam or trying to game feed by doing things like asking for likes, comments or shares. We then used posts from these Pages to train a model that continuously identifies whether posts from other Pages are likely to be authentic. For example, if Page posts are often being hidden by people reading them, that’s a signal that it might not be authentic.
