I read your answer 3 times and I don't understand it, I am not even sure we are talking about the same thing. Let me ask another way:
I am doing a huge blog project. One of the paysites I am promoting with my blogs is one that I own, I also have NATS.
If I use
www.paysite.com in my backlinks from the blog I get linkjuice from the blogs for sure.
But, If I use a nats link instead I can track users better, and more easily see which blogs are driving more sales and converting.
So, all things being equal, will I miss out on linkjuice by using nats links?
