It seems like it is time to change strategy for some of us. News about Google lists subdomains differently in its SERPs has proven.
There was a great strategy to dominate in Google SERPs but Google become only smarter… So, there will be no such chance anymore to get all 10 spots in Google’s SERPs page by spamming it with subdomains. Sites have long used and abused subdomains as a way to dominate the SERPs – rather than getting just 2 of the 10 spots on a results page, webmasters used that 5 subdomains on the same site can help to take all 10 results on a SERPs page. That is why having plenty of subdomains on your site is not so useful anymore. About this Matt Cutts said: ” in some circumstances, Google may move closer to treating subdomains as we do with subdirectories.”
One of the main and well known things for all seo experts was that subdomains on separate domain were considered by Google as separate and independent domains with its own PR, backlinks and etc. And Google now start using a filter called “host crowding” and it works as a filter for subdomains, so there’ll be only two links in SERPs on one result, a site and one subdomain. That was made in purpose to show only two spots with similar site (subdomain included) on SERP page with 10 spots.
