Hi. I've been looking into setting up some private blogs. If I purchase an expiring domain that has pagerank and decent domain authority, what do I need to do to ensure that pagerank and domain authority is kept by Google? Here are a few questions I have: 1) Should I keep the same registrar? I have read that if you switch registrars for the domain, Google may reset pagerank and domain authority to 0. 2) Should I use private registration when purchasing such a domain? I have read that if Google sees a change in ownership, Google may reset pagerank and domain authority to 0. Thus, private registration is suggested. 3) How long do I have until I have to put content up on the domain? Everyone seems to suggest immediately (ie. on the same day). What happens if I wait a day or two before putting up content? 4) Can name servers be changed or will Google reset the pagerank and domain authority to 0 if it sees a change to the name servers? 5) Can a different host and IP address be used? Or will Google reset the pagerank and domain authority to 0 if it sees a different host or IP address is being used for the domain? For those of you guys/gals who have done this before, your advice would be appreciated. The last thing I want to do is spend a few hundred dollars on a domain and then do something stupid to lose the pagerank or domain authority. Thanks!
