With News Feed ranking, Facebook’s algorithms leverage available signals and make a set of predictions that help us to estimate how meaningful we think every story will be to each person on Facebook. At leas that’s how they explain things.
The question however is, does it work? For many the answer is no and this is made worse by Facebook forcing us to see what they think are ‘Top Stories’. If you want to control what you see there is an option (see: ‘Control What You See on Facebook‘) but note; your Facebook settings will default back to ‘Top Stories’ as soon as you click away.
In the interim at least this video sheds some light on things.
