I am about to create a Private Blog Network, and I need some advice about the best strategy to register its domain names.
In particular, I need to know: if I buy all the domain names from the same registrar, and all at the same time, could this be a "footprint" indicating that all these domains are part of a PBN? I am going to use a WHOIS privacy guard for all of them, but I am still worried because the publicly accessible WHOIS data will show that they were registered exactly at the same time -- which may be an indication that they are probably owned by the same entity.
I am a bit paranoid about all this, since I have heard that some search engines (notably Google) are penalizing Private Blog Networks.
I'll take care of all other aspects of PBN hiding later, when I actually start setting up the network. Right now I only need to know if it is safe to register all the domains together.
What do you recommend?
