I've been tasked with creating custom reports and dashboards in Google Analytics to better illustrate our ongoing AdWords campaigns. For some of these reports/dashboards, I need to reach a better level of definition than "Ad Group". Specifically, I need to be able to report/filter at the "Product Group" level.
(For example, I've been asked to create a create an exportable report within Analytics that provides the comparative revenue, ROI, etc. of different Product Groups within a particularly important Ad Group.)
However, I can't seem to find a way to filter or isolate by Product Group within Analytics. "Campaign" and "Ad Group" seem to be the best definitions available. Is there a way to filter by "Product Group"?
