Looking for somone to help set up Google Analytics for Agencies so that I can monitor ad campaigns that I am running using a RTB platform. We generate the campaigns and both retargetting and conversion pixels, but don't have the ability to place GA directly on the client advertiser home page. In stead we want to find a way to integrate GA with the campaigns we are running using the AppNexus ad platform and other video ad servers that we are considering. What kind of experience do you have is setting up GA for Agencies??
