Here is something that will help.... * Remove the issue of duplicate pages, as both pages will be exactly the same * Spread the power of all that ‘link love’ to one place * Pass PR more easily http://proxyfordummies.com/2008/10/301-redirects-for-seo/
I am not sure 301 redirection for now a day works or not. especially if you are redirecting pages which are currently having page rank. Its more than couple months of time yet i haven't get back pr for my pages.
