Hmmm. I never thought of it that way. So, it might be that my listings is so much higher than my search partially because the visitors are viewing more than one listing?
As far as traffic, I am not very good at the FB or the twitter thing. Although, I have both accounts. I do however participate in treasuries and return the favor of featuring those who have featured me, in a treasury. (although, I am sadly behind - I do try to keep track) and that helps bring a lot of traffic. I have some repeat customers whom I really appreciate. And I noticed that on days that I list or renew, I tend to get more traffic. Also when I make a sale, it seems that I gain more views in the immediate hours to days following.
I too, would love to hear what others do for traffic. and more importantly generate sales!
