<snip> I get plenty of hits because I use the traffic exchanges, but no unique visits</snip>
First of all, hits aren't about traffic exchanges. They're about hits on your server when someone comes to a page. If for example, a page of your site had 3 photos, you'd have 4 hits to the server. 1 for the page, 3 for the photos.
If I for example, visit your site you get a unique visitor, you should be able to see how many pages an average unique visitors makes AND you get those 4 hits..
What I say you're looking for are two things:
1) prequalified leads - you'll get this if the partners you choose have the same ideal client as you do. They'll come to your site, like what they see, and join your ezine.
2) marketing funnel - you're looking to create a marketing funnel. i.e. they start by joining your ezine or getting your free course, then over time they become clients.
