Advertisers are always out to glean as much data from web users as possible. Facebook is one of those advertisers that targets ads at its users using information from profiles. The social networking giant has announced that it has expanded those targeting capabilities with the roll out of Audience insights.
Audience Insights gives Facebook the ability to target users based on metrics like demographic traits, geography, and their purchase history. Facebook says that before the roll out of Audience Insights it only offered advertisers an audience estimator tool.
