Chango Deal With Facebook Uses Google Data - Business Insider: "It's a significant move for Facebook. Previously, advertisers could target Facebook users with their own data collected from "cookies," the little pieces of software that web sites drop onto your browser as you surf the web. That data tells advertisers what you're interested in -- cars, volleyball, whatever -- but it often doesn't indicate what you're shopping for.
Search data, however, does. Anyone searching for "Prada shoes" is likely interested in buying some. This is called shopping "intent" data."
