Ok so I have a main webpage in which I have several wordpress blogs linking to. Everything is "insurance" related and there is no crosslinking. All of my domains as a whole including my main sales website are hosted on the same IP. Would it do any good to move these blogs now to separate IP address since the WHOIS history has already been published? As most of you know Google likes natural link building. If all my blogs that link to my main sales page are on 1 IP then that is not natural link building. If I move the sites to different IPs now then Google may still be able to figure out that I own the domains since the WHOIS history exists. Any thoughts?
