Subdomains can alleviate content farms.

Google's search quality chief Matt Cutts replied to Edmundson that he might want to try subdomains and other ways. Thus, HubPages began testing subdomains at the end of June, and it has already gained positive effects. After Google adjusted its algorithm, the pageviews of the articles by Edmundson on HubPages had fallen by 50%, but in the first three weeks after using the subdomains, they have recovered to the original level. The traffic of other authors has also been restored.
