The process is automatised.
A new subdomain for each page, even for "search terms pages".
As I see, this a new trend in my niche ;(
Mentat - While possibly this may be new for your niche, such auto-generated, wildcard subdomains are an old trend, long recognized as spam, and not a good model for long term success. I'm surprised at the longevity of the site you mention.
...even for "search terms pages".
Yes, these probably are search term pages. In 2009, AOL (yes, really) tried it via Love.com....
AOL 'Creating Websites by Automated Methods' - how will G react?
Love.com was a mash-up of scraped and borrowed content, pretending to be a new kind of search engine. I'm not sure how an auto-generated subdomain can get its seed content any other way. Before this type of site went to mashups of scraped content, spammers did point links at search results pages.
As I remember, there was an initial surge because of the borrowed authority from AOL, but Love.com was eventually recognized (either by Google or by users) for the spam it was.
It's a technique that I feel shouldn't flourish for long in your niche, particularly if the sites don't have AOL's link juice to pour into it, and again, I'm surprised it has. What more can you tell us... without getting into specifics... about the site that has been growing?
It does not matter the content of the page, if the keyword is in subdomain AND page URL!
I've worked with sites that had keyword subdomains... and I didn't like the setup. I can also tell you that the keyword in the subdomain isn't magic.... there's got to be another reason why the site is ranking.
