I wanted to ask what is the best strategy for this situation:
We have a site example.de and we are launching a dedicated version of it for the Austrian market. Since both .de and .at sites use german language at the first few months we are going to show the same content in both sites (both domains point to same servers which choose what to show dynamically). Will this penalize our rankings because of duplication (and how can we tell google that "at is a copy for the de site").
In a month or two, .at users will start to see exclusive content for their region (though some parts of the site will stay the same).
Since we are not trying to cheat or smth else, how can we ensure google doesn't falsely penalize us?
Thanks
