Facebook is tracking user history & preferences more extensively to implement greater personalization in news feeds and advertising.  This is documented in following links:



The social network announced this week it will be rolling out expanded, personalized notifications in the Facebook across iOS and Android devices for users in the United States. Facebook notifications may now be your first stop in the morning to catch up on everything from friends’ news to weather, sports scores and what to expect later in the day.

“Every day, people use their notifications to keep up-to-date with their friends and family. We’ve heard feedback that people wanted to add important information that they can easily see, all in one place,” Keith Peiris, a Facebook product manager, said in a newsroom post.

The mobile update is bringing a set of new card-like notifications that will include information such as sports scores for teams you have liked, TV shows, weather information and friends’ life events, among other updates.  People with location history enabled in the Facebook app will also be shown updates for local events, movies in nearby theaters and lists of restaurants with links to their Facebook pages and reviews, according to the newsroom post.

A user’s notifications settings still won’t change with the update, meaning there’s no need to worry about getting a sudden avalanche of notifications. Don’t want to see a certain type of update? Not a problem. Facebook says users can customize the information they see by tapping the arrow to the right of each notification card.
