4. Advertise & Monetize Content

Google can do three things to make money out of the content of its social ecosystem: Firstly, like Gmail publishes ads in the mailbox of a user relevant to his interest, Google can allow advertisers to advertise within their ecosystem. Secondly, it can provide the marketers with more relevant social consumer data to help them advertise accordingly. Lastly, the content on the social ecosystem can be turned into in-line ads as it is done now with Google+ and Gmail.
