Anyone have an answer to this question? I want to add another blog to my domain, www.ItsGottaBeRed.com (and don't really want to pay for a new domain, not yet anyway), but I don't think it is good for deep-index SEO having my blog way down in some sub sub sub directory in the hierarchy like my mountain biking blog is at the moment. What if I add a virtual domain, e.g. blog.ItsGottaBeRed.com? Presumably "the big G" doesn't treat it as a separate domain for PR purposes, but what are the advantages and disadvantages of virtual domains for SEO? markowe
