I am planning to build my private small high PR network to improve SEO of my own websites (no commercial usage at all).
Well the approach is simple: going to auctions, analyze the existing domains and try to buy it.
My goal for now its aiming for PR3 websites and for this i have analyzed the PR being real, amount of Backlinks, quality of backlinks, refering domains, age of domain, Domain authority , etc.
My major doubt will be more about the juice of a domain like this will give me being a domain lets say with 100 backlinks and 20-30 refering domains or a domain with 100k backlinks with 5-6k referring domains, in terms of power of the backlink for the money website will have the same result or the one with more backlinks and refering domains (assuming the backlink quality are similar) are better.
I am telling this because the 1st scenario the domains are quite cheap, lets say 20-30 bucks a pop and second scenario should be 5 times more expensive.
So i would like to know what the experts could say about this?
