Six months ago, Google delisted all sites on a co.cc domain name. Today, they seem to have all returned.

A search for [site:co.cc] currently returns 105,000,000 results.

Google originally delisted the co.cc subdomains because Google saw a “very large fraction of sites” on that subdomain to be “spammy or low-quality” and felt it was warranted, in this case, to simply block the whole subdomain from showing up in Google’s results.

I am not sure if this change was intentional or a bug where after we write about it Google will delist the subdomains again.

Here is what the results looked like previously:

Now that many of the results are back, you can check for yourself to see how spammy or low-quality co.cc sites are or are not.
