if you haven't already, get the membership, then get a domain name that's yours. so at least if your advertising anything, it starts with your link and not this place. if you ever had to sell it yourself, then your link is already out there some place. i always try to add http://www.MikeSavad.com where ever i can.
always have descriptions and good keywords - more at least.
don't crop your name at the bottom of the image
do turn on the loupe, people like to know what they are buying.
always have new work
always advertise when you can, get new people on twitter, facebook etc.
find blogs, news articles, and any other place your name can be found.
don't include links in your bio, or people may leave and not come back.
