Ok, so basically the unlimited domain hosting under one account is pretty much subdomains that point to my main domain.com on my host.
Like domain1.com would be my main, and then newdomain2.com would be a subdomain of newdomain2.domain1.com (which points to newdomain2.com).
How does this affects PageRage?
Say, domain1.com all of a sudden increase its page rank to PR 4, but newdomain2.com would not be affected right? So, if newdomain2.com drops a pagerank, it would not affect my main domain right?
Also, if I have high page ranks for both of my main domain and all my other domains (subdomains) and decided to switch to a new webhost, would it affect my pagerank as it will get new IP addresses?
