I was reading Joost de Valk’s blog where he mentioned an example of Wikipedia subdomains clogging up the SERPs.
The subdomain problem is happening with numerous other strong Web sites also.
Here is a somewhat contrived example where most or all of the first 415 results in Google are subdomains of CraigsList.org:
http://www.google.com/search?q=salon+spa+fitness
Hmmmm…
I can think of a another example of this subdomain hell in the Google SERPs where the issue is similar to Wikipedia—the subdomains are translations of the main domain.
If you have a domain with massive link popularity you could probably use this subdomain technique to great advantage.
(At least until Google fixes the problem.)
