@scottb, welcome to the club. Do the brands have similar widgets/information or are they at all unrelated? If so that would cry for new brand domination in not competing areas.
@back, @cos, it is okay to make money with their machine, but the way they are doing it is not okay. They say donīt do this, donīt do that but they keep doing it.
The average user donīt see the shifts in serps as long amazon/ebay is first. But the avergae user donīt see that there is much more ads, either. They donīt know that they are clicking on ads, they donīt know that they been tracked by google. They donīt know that they obviously misleaded by search suggestion. As long the poeple donīt care, there will be no turn around.
