M8INTERNET, Ok, I can see that if I set up a new campaign for an area I could see the expenses for that campaign. The problem is that currently I only have a year of data for worldwide campaigns and I need to get from that data how much of that spend was spent for Arizona. which will be the test area I work on. I want to be able to compare the spend after I work on the area with what was being spent before I started.
There's a report for that. It's called Geographic Performance. It will show data split to metro areas.
Lucid Web Marketing, Thanks. It's actually an option under the Dimensions tab for the New AdWords, but I found it.
