Hello

We are a company with a website in several languages, one of them is portuguese. Our market is 2 times bigger in Brazil than in Portugal, but obviously Brazil has more potential in the future. In domain.com we have our main site in English.

What would you use? pt.domain.com, br.domain.com or domain.com.br?

In the first case, it means just portuguese, in the second Brazil but it is not geolocalized, and in the third, you are almost ignoring Portugal users...

Duplicating content, doesn't seem to make sense... The content is basically international, so it is just the language that matters.

Any help will be very much appreciated.
