Historically, interest-based targeting on the social network hinged on users' own declarations of their likes and interests in their profiles, as well as Facebook pages they had "liked," according to Brian Boland, Facebook's VP-ads product marketing.
Now, Facebook is using the passive data -- where users go on their PCs and phones -- to make its own ads smarter. Advertisers who want to reach Facebook users who are interested in camping, for example, will be able to reach that audience with greater accuracy. "There's just a more robust set of information that informs that you're interested in camping," Mr. Boland said.
