As vastly different companies starting from incredibly different starting bases, Facebook and Google are both royalty in the Internet world, but who is King? Facebook might have the users, but what do the users use as a search engine? Google.

What Facebook does well is act as a service. As Mark Zuckerberg puts it: "we don't build services to make money; we make money to build better services." With this in mind, Google wins the ad game. In the line-up against Facebook, growth, performance, targeting and format are the clear winners for the Google machine.

With the release of the Facebook IPO coming in at over $100 billion, don't worry; the social giant might be lagging behind Google, but they are hardly slumming it.
