My site - about 2 years old - is indexed and ranked in Google, albeit after a one year hibernation in the you-know-what. It consists of a home page and about 40 subdomains - each containing unique content, but still structured around a loose template. The site was set up as ht*p/sitename.com with no "www" included and all links were requested to that structure though, yes, one or two have surreptitiously added the www. Now, each subdomain is slowly only showing a URL (no title, desc., etc) in the SERPS. Is there something inherently wrong (vis-a-vis Google) in setting up this way? (I understand from what I've read that I may want to contact all those who've added "www" to the link and ask them to remove it. Undertandably, an intentional campaign would be more hard to fight.) Is there something else I'm missing? Am I supposed to introduce some type of redirect or something? If it's not glaringly apparent already, I know enough technical things to get a site up and running but not TOO much beyond that. Any help? How exactly does this set-up help get a dupe-content penalty?
