A couple of weeks ago, Google made a change in their algorithm. Prior to the change, a subdomain was considered more or less like a separate URL. Matt explained the reason that presented a problem was due to the fact that multiple subdomains and main domains had a tendency to dominate search listings for some queries – specifically, for example, elaborate long tail query strings.
We did hear complaints that for some types of searches (e.g. esoteric or long-tail searches), Google could return a search page with lots of results all from one domain. In the last few weeks we changed our algorithms to make that less likely to happen.- Matt Cutts
