John . . On the other hand, If I get an email from an upholsterer that repairs classic car seats that has just finished building his website, and he asks me for a link on some early Chevrolet pages. I will tell him I only list free ads in year make model format. and his ad would not fit that format, It would cost him. (I need to cover the costs to deliver free ads that supply my traffic)

If I place a nice link to him on a couple of chevy pages... Google (and other search engines) would find this Classic car upholstery site without problems. and anyone searching the net would find him for the term classic car upholstery

I think this is a useful service, not intended to destroy search results. rather to enhance them.
two inbound links from a PR2 is all this site needs. ad to that the fact that my users will find him.
I think this paid link is perfectly ethical...... Tell me if I am wrong.

My site neds the $100 and his site needs to get listed. Thats all good - (I think)

How would google find this site for its searchers otherwise?

P.S. that is my business model. it is very effective and I have many thousands of loyal users.
