Hello, im buying PR 1-4 Domains and i wanted to get some do's and do not before i jump into it. What i wanted to do was to buy these domains and host them on atleast two different hosts, then make a unique blog with each domain along with unique content on all of them. They will be interlinking also, and hopefully with all the unique content i will be able to keep the PR or maybe even boost it right? How can i keep the PR of a expired domain? If i buy a expired domain and rehost it and put content on it would i still have its PR i bought it with? thanks ill give +rep!
