I'm building links for one of my websites and today I was checking my rankings and I noticed that if I search on Google.com in my country (Slovakia), my positions have not changed. However, when I searched on Google.com using a US proxy, my rankings got worse there (for one keyword I lost my ranking, other one got worse). I wonder why the search is different in the US than in my country? And can I now expect that the rankings will be the same in my country soon like they are in the US now? When I searched using the proxy yesterday, Slovak rankings were the same like the US ones.
