301 or What?

[SEObleu.com]

Can someone please tell me the 100% correct way to set this up.  Would I be right to set up a site this way...

type in the browser..."example.com" and it re directs to "www.example.com.

or,

if i type in "example.com" it goes to example.com.

or if I type in "www.example.com" it goes to "example.com"?

or, type in "www.example.com" and it goes to "example.com"

wouldn't most site link to a "www" version?

PS

whay isn;t the correct way set up by our HOST.? They should know what is most beneficial?

Thanks

good question, I think a lot of people are having the debate recently to find out which version of the website to use

1. Use the non www version.

2. Use the www version on websites.

Personally from sites I have worked with more people are linking to the www versions of the sites so then yes continue to use the www site.

Yet in some new branding campaigns people drop the www, then my advice for the life of the site is not use the www in your link building, I have also seen instances of where I blog about something link to a site using a www, then they sent a email telling me to drop the www in the link.

But form my research on big sites around 85% of people still link with www, sure branding and other factors may sway this.

what I just noticed it that seomoz goes with the "seomoz.org" to the "www" version. Does anyone else see that?
