Till now I was having a trilingual site (english-italian-german).
where someone could reach the appropriate language from a url of this structure...
www.abcd.com/english
www.abcd.com/italian
...............
leaving the default url abcd.com under my main visitors language.
What problems I might face if I force the default url to show according to the area someone visits my site?
Please help me as I thing SE might face this as spamming or not good way to promote my content
