So that is a confusing little nugget of information…

.co since it is sold often as a company domain, so its not treated like the other ccTLDs. Even though its the domain for the country of Columbia.

So the question of duplicate content and the apparent lack of a rule if there is content on multiple domains gives the rise to an interesting question….

Lets say you have Spanish content, on .co and .com. Does it both rank? Or not?

Curiouser and curiouser!
