Hi all.
A few days ago I started to build free sites and submited them to linklists and I am a bit depressed from traffic quantity they are getting. I try to build, clean, nice, surfer friendly SEOed sites, but looks like it is not enough to make money

. Could you please look at them and tell me if there is anything else I can do to bring more traffic to them? Or is it wrong, maybe too small, niche I selected to start with?
Sites are
http://www.perfectpissing.com/toiletpissing/
http://www.absolutepissing.com/outdoorpissing/
http://www.perfectpissing.com/maturepissing/
First ad on the index.htm page is always replaced with recip table, these version I try to submit to DMOZ.
Thank you for any sugesstions.
