Please help me out by telling me how should I divide my campaigns between America's states and/or cities (BTW, 10 campaigns would be more than enough for the American market).
I wouldn't suggest dividing your campaigns by city or state unless there's a strategy reason to do so... such as - only offering your product to residents of particular states, having different marketing messaging per market, or knowing that there are dramatically different ROI levels per market.
Unless a substantial reason exists, you're giving up an awful lot of flexibility by not targeting the US as a whole via one set of campaigns.
Thanks for trying to help.
I do mean campaigns (not sites) and I do think there's a good reason why I should have different campaigns (for bid differentiation).
In past international campaigns, we categorized the different target market by GDP and geography (that is, a North America campaign, a West Europe campaign, a Middle East campaign, and so on).
My real question is what would be the best segmenatation for the US market.
Thanks again,
