If you're building sites with quality content, why go to such lengths? What does Google care if you're a publisher with several internet properties in the same niche? Do you think Google cares that AutoTrader also owns TruckTrader and BoatTrader and cross links between all three? I doubt it.
What am I missing?
Or is all of the lip service toward building sites with "quality content" done with a <wink> and a <nod> that has gone way above my head?
