I have a website pretty much ready to go and i'm looking for a domain that will help with seo. I have one in mind but i'm now considering buying an existing domain of say PR4 or whatever with a couple thousand backlinks atttached to it. Can anyone tell me if this PR and these backlinks will stay once i take possession of the domain and put my site to it? What is the correct way to go about getting this PR and backlinks ie should i buy an existing domain or expired domain and will google disregard all the backlinks and PR once the domain becomes registered in my name??
