I was planning on posting a little how-to on using Google Analytics, specifically with Etsy. Now available in the Shop Setup section under Web Analytics on your Your Etsy page. The directions for setting it up are fairly easy.
But, since Jill of Liv'n Good Jewelry has done a hell of a job with said article already, I give you link. http://livngoodjewelry.blogspot.com/ The info includes how to use the info to determine the best time to list new items, and the excellent advice not to obsess (are you spying on me, Jill? I'm a Heartomatic junkie....). It's kind of like starting Weight Watchers and weighing yourself five times the first day (I've NEVER done that......)
Enjoy. This is an excellent tool a long time coming.
Did I mention she has some beautiful items in her shop, as well? :)
