Is there any preference - what people type more in address bar - domain name with WWW or without? I am choosing which one to use for promotion by link exchange and want to make the right choice (if it's possible ) I know that later it can be fixed by 301 but want to do it right from the beginning. Does anyone have any stats for this?
With. If people are going to type in your URL, they are more likely to remember and type in www.comain.com than http://domain.com.
This has been asked dozens of times. Pick one, stick to it and 301 redirect the other one to the one you chose.
Actually, you can see "www" as a subdomain. SOme webhosts support www.domain.com and some domain.com. It depends on the apache configuration. Moreover , some webhosts, support www.subdomain.domain and some only subdomain.domain.com . Usually, the natural way to build links, is towards www.domain.com .
