I want to promote my paid Music Directory and I want your opinion. I'm offering 3 types of submitions (3$ with recip link, 5$ regular links and 7 featured links). These will be the only income for the site. Do you think that using Adwords will help my site to grow without losing any money? Do you think that on every 100 visitors (3-7 cents/per click), one will submit a link?
