Just wondering if anyone knows the affect on seo of a recurring subdomain. E.g. I want I register my company name "intenseIM.com". What if I then add a whole lot of subdomains as web 2.0 properties like this: "dogstairs.intenseIM.com" "frozenpipes.intenseIM.com" "spiderbites.intenseIM.com" Etc. Would this affect the PR for these sites considering the unrelated and repeating subdomain? Would it be much different after penguin (EMD demotion)? Regards, Ben.
