Google lists subdomains like directories

Filtering diferent subdomains for same site in serps

[Gus_R]

Hello, for queries with very competitives keywords seems subdomains are grouped with main domain.
I found for the same three word phrase 243,000 results in google and 1,300,000 in yahoo.
Funny thing is I can only see 4 pages of serps, then appears the message: repeat the search with the omitted results included.
I like this, there were a lot of spammy competitors with many subdomains like [aCityOrState.keywords.com...]

Gus, I suspect that those pages were similar. Google can list results from multiple subdomains of a domain, but if results are similar (whether on subdomains of a domain or not) then they may not be shown until you search with &filter=0 (or click that message you saw).
