Officially, Facebook announced an update on their blog that there are going to launch some features like “trending topics“, “When lieks your comment or share”
Facebook said :
Our goal with News Feed is to show everyone the right content at the right time so they don’t miss the stories that are important to them. We’ve heard feedback that there are some instances where a post from a friend or a Page you are connected to is only interesting at a specific moment, for example when you are both watching the same sports game, or talking about the season premiere of a popular TV show. There are also times when a post that is a day or two old may not be relevant to you anymore. Our latest update to News Feed ranking looks at two new factors to determine if a story is more important in the moment than other types of updates.
Feature- 1 : Trending Topics
One way Facebook will rank timely content higher-up in the news feed is to show stories about trending topics as soon as they happen. With this update you will know immediately what your friends or favorite Pages are saying about the most relevant topics.
Feature-2 : When people like your comment
Facebook’s second update to the news feed looks at the rate at which people are liking or commenting on a post.
For example, if people are engaging with the post right after it is posted, and not as much a few hours later, this will tell Facebook that the post was most interesting at the time it was posted, but potentially less interesting at a later date.
