I have just given a talk about Google Analytics Concepts. I have explained basic concepts that anyone interested in maximizing Google Analytics usage must know. I have talked about generic web analytics concepts like metrics, keywords, marketing campaings, segmentation, etc. I have also reviewed specific Google Analytics concepts, such as which cookies are used, how to install the tracking code, how to integrate Google Analytics with AdWords, etc.
I recently passed the Google Analytics Individual Qualification test.
If you are interested in become a more knowledgeable Google Analytics user you should have a look at Conversion University, a set of online presentations that you can watch free of charge, or come to the talk I will be giving next week about Google Analytics concepts (in Spanish).
