If you use Facebook, then you probably know that the social networking site uses a formula, or algorithm to display status messages in users' News Feeds. The site doesn't display all content in your News Feed by your "friends" nor by companies, brands, or groups you follow.
Facebook explained the recent tweak to its display algorithm for users' News Feeds:
"... we ask thousands of people to rate their experience every day and tell us how we can improve what they see when they check Facebook — we call this our Feed Quality Program... we’ve found that there are stories people don’t like or comment on that they still want to see, such as articles about a serious current event, or sad news from a friend. Based on this finding, we previously updated News Feed’s ranking to factor in how much time you spend reading a post within News Feed, regardless of whether you opened the article... we’re learning that the time people choose to spend reading or watching content they clicked on from News Feed is an important signal that the story was interesting to them. We are adding another factor to News Feed ranking so that we will now predict how long you spend looking at an article in the Facebook mobile browser or an Instant Article after you have clicked through from News Feed. This update to ranking will take into account how likely you are to click on an article and then spend time reading it..."
So, the algorithm now uses time spend reading a post to decide what it thinks will be relevant to you -- and then display that. If you don't spend time reading content from a particular source, then Facebook probably won't display it in your News Feed.
Want to see in your News Feed everything your "friends" posted? You can't. Do your "friends" see everything you posted? Nope. To see everything, you'll have to visit the Timeline for each "friend," business, group, or brand you're connected with. To get around this, some users "tag" their friends in the Comments section of status messages so they don't miss something important.
What are your opinions of Facebook's algorithm?
