I am getting very poor results from my Yahoo PPC campaign.  They are not even delivering enough traffic to reach my daily max.  I am getting lots of impressions, but my CTR is .02%, which is way off. Is anyone else having this problem?

I have never used Yahoo or Google at all for PPC.  I do use traffic generators and paid PPC through PPC email programs to generate traffic, but that's about it.  Those that I use are to bump up traffic numbers and get people to the site....if they ever convert to clicks or such that's kind of an added bonus. 

For your kind of site I would think about webrings for some free traffic, directories, and good old email promotion if you have the budget for it.   Mailings also help. The web is a great outlet but the hard thing many forget is that if you are selling something, there are 100+ others selling the same thing.  You need to find a way to make  yours stand out.
