I was recently looking over some of the websites that my website appears on in the "Search Network" and I'm not really sure whether it's worth the investment. A lot of the traffic from the search network is from websites such as
www.villagecenter.biz which is basically just a parked domain. I don't mind receiving traffic from websites like Aol Search and Ask.com but partners like
www.villagecenter.biz will basically bring you mostly "garbage" traffic that probably isn't worth more than $.05 a click.
