I want to start building quality mini niche sites, I have a few questions. 1. I want to start doing manual SEO, meaning manual backlinks so I can get a feel of it. What are the best ways of going about that? 2. What are some good ways of finding High PR Sites and pages for blog comments, etc.? 3. For automation, what tools seem to work best for ranking mns? 4. For keyword research, what is a good CPC to go after? How do you know if there's not too much competition? Basically, how do you guys rank your MNS?
