According to the Seroundtable.com, Google has been updating their indexing systems to treat more ccTLDs, country-level top level domains, as generic TLDs.
As we already know some of the favorite ccTLD’s of domainers like .Co, .Me and .Tv made the list.
If your using a ccTLD domain name and if its on the list Google will rank your site as a generic site, .com, .net and .org included.
If you’re using a ccTLD not on the list, then Google is treating the domain in its country code sense and you should not expect to get much traffic or ranking outside the host country
“Some country specific TLDs, ccTLDs, have been used by a large number of webmasters as more generic TLDs. So Google has decided to treat 20 ccTLDs as if they were generic, and thus not weigh too much localization to sites using those ccTLDs in the Google algorithm”.
The list of 20 ccTLDs that Google now treats as generic are:
Google said that this list “may change over time”.
