I'm going to be doing some Google AdWords on behalf of a company already doing and running adwords. They have a large amount of broad keywords. I will be targeting long tail keywords, but this longtail will end up having some overlap with their many broad keywords. Both of our ads will be going to the same domain though. I know if you have overlap normally on ONE account, they pick the keyword with the higher quality score. However my account, and the company's account are completely separate. They will not give me any access to their accounts. How will this work?
For example if they have:
widgets
and I have:
model A widget
Who's ad will show?
