I was looking at godaddy auctions and checking the backlink profiles for some domains for a private network that I am trying to start. here is what I have found: anything that is obviously good quality is too expensive because everybody is trying to get it. so i cant afford those. Then there are these domains which have healthy backlinks (all natural, no spam, no comment blog bullshit) BUT not too many backlinks. For example, maybe 10 healthy backlinks. PRs are low (PR0 and PR1, maybe PR2) what do you think of these? If I am trying to set up my own PBN, how many healthy backlinks should each domain have? I am thinking 10 is not enough?
