I do like Google Analytics, and I am ecstatic that Etsy has included the script to enable GA. What usually drives me mad is that it's not real-time. When I made the frontpage, I would have loved to see those stats right afterwards, not waiting 24 hours.
That graph? It's my shop stats - the spike is the frontpage day. I usually average 50-120 visits a day, frontpage kicked me up to 350. Nice, eh?
What I also found out through Google Analytics - visitors are coming in from pretty much everywhere. I haven't had visitors from Africa (except for South Africa), none from Belarus, none from Greenland, plus some other obscure Eastern European countries - other than that, they are from all over the world.
Which again underscores the importance of
a) adding sizes in inch AND centimeter
b) offering international shipping.
