I am building a private network and currently have about 30 domains with wordpress installed. I'm considering creating a handful of subdomains on each domain with a separate wordpress blog. So let's say I create 10 subdomains per root domain and that originally I would have one link on each root domain going to my money site. Now, I'd have 10 per domain, 1 per subdomain. Since google looks at subdomains as essentially separate domains, will this method increase the number of unique inbound links in google's eyes?
