Yes, I'm completely addicted to it but I think I'm getting to the end of the road with it. What's great is, I created one that I'll be able to export as PDF to send to potential advertisers. That way they get everything they need:
Ages
Gender
Uniques
Pageviews
Interests
Breakdown of devices (desktop vs mobile vs tablet)
And maybe one or 2 other things
I think sending a PDF like that would be much more powerful than to just simply state the stats. gA makes it super easy once you figure out how to use the dashboards.
