example.com, seoexample.com, designexample.com are all pointed to to the same content. Let us say all three are pointed to public_html which means all use the same content. And all are indexed by google or others. How does that affect to duplication?
I am now not sure which one to use. I have three domains. one domain is 7 month old and has not PR and does not contain any keyword with what I am going to cover. Second domain is 3 month old, has PR 2 and contains two keywords. Third domain is a root domain of my account and has registered new but contains three keywords of what I am going to cover but nor PR or indexing.
I need suggestion which one to use a base and redirect the two to that one. I want for a long term so when I build links, I do not lose time switching between three.
I know best seems the second one but not decided yet. Any help is appreciated.
