Welcome to the Q&A Forum

I have a question regarding how to use my url, we are a Swedish-based website which have the url, http://interimslösning.se/ (that contains the Swedish letter “ö”) so the url can also be written as http://xn--interimslsning-3pb.se/. Which of the following url should I use for my backlinks, http://interimslösning.se/ or http://xn--interimslsning-3pb.se/ ? What is the difference between them regarding SEO? And is it good or bad to use letter like "ö" or other characters like that in your url? I was thinking that maybe it is good to use the letter "ö" for local search optimization in sweden, but i don't know.. Thanks in advance! Greetings,
