Okay we all know unique ips (especially c-class) are good. And google devalued sub-domains a while back, to approx directory level. i.e. they treat everything as one site. Now what about subdomains on different ips?? I've an idea that will require thousands of domains, to generate thousands of "unique" sites. Obviously putting them all on the same ip, will get them tied together, but I really don't want to pay for thousands of domain names. Any idea folks?
