www.domain.com vs. just domain.com on Google
 

In Google Analytics, you can ask the engine to disambiguate and always serve results to your site as either www.domain.com or just domain.com.

I didn't used to forced links to go to one or the other and I think most links in to my sites are probably www.domain.com.

Is there any disadvantage or advantage to using that tool to tell Google to always go to the www version?

Anybody?

your site with www. and without the www. have different PR's

I noticed that. Does it make a difference if I tell Google Analytics to regard it as all links with the www or all without?

It's about PR i think,looks them different,so better put www. always

Yes. If you try to submit both ways, google will send you to the sandbox. Been there, done it. Be careful.

try to permanently redirect domain.com to www.domain.com using .htaccess... :)

i always alias domain.com to www.
