Before you do anything you should read the introduction about reporting with Google Analytics: http://www.google.com/support/analytics/bin/answer.py?answer=99014
Then these are the next steps:
- Design your custom report (know how you want to present the data, learn about dimensions and metrics, preview your report).
- Build your custom report (watch the video below, it’s self explanatory. It will give you an idea about how easy is to create custom reports with Google Analytics)
- View and mail out your report at scheduled times (once the report is setup the data is available immediately. Test it out and see if it makes sense to you)
