Ok with so much emphasis on pay per click, I was forced to start this thread. I believe that you should forget pay per click as a way to advertise your website and go to pay per lead and here is how and why. How Write a free ebook and then join a pay per lead network such as maxbounty.com. Now start a pay per lead campaign where you only pay when someone visits your becomes a member and downloads your ebook. Set a price for the lead between $0.30-$0.05. Why? You can get a lot of free traffic this way. Not everyone will register and download your ebook but if you make your ad appealing enough, people will visit your website which you do not have to pay for! And if someone registers you have their email. Now combine this with an email advertising campaign and you are sure to make up the money you spent to attract the visitor. Give it a try. Good luck!
