301 Redirect Htaccess Hi,

My client wants me to SEO his site. He provide me the URL http://www.example.com and when I check on it, it is redirecting to http://example.com/ which clearly uses 301 redirects. I check on the backlinks, the
# http://www.example.com : 26 backlinks
# http://example.com : 0 backlinks

but the SERP for all keywords shows that it rank for non-www version and no result/zero pages for www version. I told my client that I will optimize his site using the non-www version since the site has been indexed with the non-www and the keywords have rank with the non-www.. But he is confused of optimizing the site in the non-www version because of the backlink results. And even ask why the site keywords rank with the non-www if it has zero backlinks. Maybe I wasnt able to explain him appropriately..

Please correct me if I am wrong.. Am I correct of optimizing the site with the non-www, right? And what is the appropriate way to explain this to clients.

Additionally, why would google rank the keywords if it has zero backlinks? 10 of his keywords 6 of it shows in page 2, 3 and 4.
