Google Removes Several Popular Subdomains from Index

 

In an update to its search indexing algorithm, Google has recently made the move to several popular free subdomain providers from its index. Free subdomain service providers offer users the ability to have a shortened domain that can act like a real domain, allowing a more attractive URL than that offered by regular free hosts.

While these sbdomains are offered for free to the public at large, they were grossly being being abused by hackers and spammers looking to capitalize on the multitude of subdomains available to them. Reacting to the volume of phishing and spam attacks stemming from these domains, Google decide to outright ban many of these services, effectively removing over 32 million sites in its index.

The free subdomain services affected include:

Co.cc
Co.be
Cz.cc
Uni.cc

There are a number of other free subdomain services, which are unaffected by this change – some provide DNS like the services mentioned above, while others are merely URL shortners and simply redirect to your actual website.

Co.cc appears to have filed to be re-included and has taken action to create a DNS blacklist that prevents hostile sites from using the service, but their preventions look to be too little too late. It appears that Google may not be giving them a second chance, as the reinclusion request was submitted nearly a month ago with little change in the SERPS so far.

Update: Uni.cc and Co.cc have shutdown in spite of the issues, and possibly due to spam/abuse reports.
