If a value of a link from third party website is 100, what would be the value of the link from that website if it would be owned by me? (for Google SEO; given that all other variables are the same) - 10? 50? 100? Have you done any tests on this? What are your experiences? And if I want to make my websites look like they have different owner, what should I be careful about? Besides different domain whois, class C IP, content and design. What about referrer code in my affiliate links? Thanks...
No one can answer the level of measurement you think of, the rule is get links from highly related sites or any site that should answer "why your site should be listed there"..
