A User of Google Analytics
This plug-in is indispensable for anyone serious about getting the most out of their Google Analytics data. It may take a little bit of time to understand the structure of data coming out of the GA API, but once you have mastered that you can run very sophisticated, multi-dimensional reports and analyses very quickly. I combine data pulled from the API via this plug-in with the built in spreadsheet features (charts, pivot tables, etc.) to create daily, weekly and historical dashboards as well as for one-off analysis of specific questions. I find it far superior to similar third-party options I’ve seen over the years.
One resource I recommend while you are learning the GA API is this "Dimensions and Metrics" explorer from Google: https://developers.google.com/analytics/devguides/reporting/core/dimsmets
