I have a website for which i want to do SEO. But the website non www version like domainname dot com. I feel that for SEO of this version, the backlink aprrovals will be less when compared with WWW version.

Now I would like to redirect from domainname dot com to www dot domainname dot com and submit it Google Analytics and Google Webmaster tools and do SEO for www dot domainname dot com. I request friends to clarify me in this regard
