Is that still the case? Do we know how much of Google's ad revenue is directly from their own search product? Obviously the genius of putting ads on a search engine is that it's a perfect fit: the users are literally typing in what they're interested in. But surely Google is also making big bucks now from ad products where this isn't the case (or is less so the case), like third-party web ads (AdSense) and mobile app ads (AdMob), as well as embedded ads in other Google products (like Gmail), and presumably those do rely heavily on tracking user behavior.
