LONDON: Facebook is lifting the lid on the algorithm that decides which posts appear in its news feed, as part of a drive to be more transparent and offer greater control to users.

The feature "Why am I seeing this post?", being rolled out from April 1, offers some insight into the tens of thousands of inputs used by the social network to rank stories, photos and video in the news feed, the foundation of the platform.
