Facebook may be adding to the list of things it knows about you.
The social network is reportedly experimenting with new technology that tracks and collects data about a user's activity on the site, including cursor movements, according to the Wall Street Journal. The technology is being tested now with a small group of users.
The technology can supposedly determine where a user is hovering his or her cursor on the screen, meaning it could be used to determine the most appropriate places for advertisements.
The technology also tracks whether Facebook's mobile users can see their News Feed at any particular time from their smartphone.
Facebook will reportedly decide "within months" whether or not to continue this data collection and analysis. It could be relevant for targeted advertising where Facebook has already seen quarter-over-quarter growth in 2013.
