Google has always been looking to further improve their search results and after the search giant did some digging online, has decided to block co.cc subdomains. How is this linked to better search results?
It seems that the Korean company providing the subdomains are doing so at a cheap price or for free, and it turns out in this case free doesn't necessarily means good. Scans from Google revealed a majority of the sites contained malware or were just spam. Even though Google has proved itself vigilant against such actions on the Web, it may need to look for another solution as spammers and other unsavory web characters are rapidly moving onto other subdomains even as Google has blocked the co.cc ones.
