When I saw this graphic, I thought it was awesome, so I wanted to reproduce it here.  It comes from Mike Blumenthal’s post: Infographic: Owning Your Local Web Equity
Mike wrote this about what the graphic.

The goal of this infographic was to provide a foundation for that understanding from the perspective of long term investment in their marketing efforts. It is not so much a guide to those marketing priorities as it is a guide to understanding the trade offs in loss of control as you move your efforts onto the platforms controlled by others.

Download the graphic, read it, take it in. Thanks to all involved in putting this together
