A post by Tedster at WebmasterWorld, where Tedster said: News flash from Las Vegas PubCon. Matt Cutts informed us that Google will very soon begin treating subdomains and subdirectories the same in this fashion: there will be only 2 total urls from a domain in any set of search results, so no more getting 3, 4 or however many spots via subdomains. We didn't get any more information than just that basic heads-up.
This is a significant change, if it happens. For example, a search on google at Google returns ten results from Google, nine of them from google.com and one from google.org. Here is what I see right now:
Now, if this rule is applied to everyone with the exception of hosting sites such as blogspot and similar sites where it wouldn't make sense to apply the rule to, then Google will be limited to two results per search.
