301 redirect & duplicate content?

I made a redirect to my new domain:

RewriteEngine on
Options +FollowSymlinks
RewriteRule (.*) http://www.domain.com/$1 [R=301,L]

in .htaccess

Did i do it right? Won't there be any duplicate content issues?

 

Off course NO!

 

if you are redirecting to a new domain and both the domains have same content, then you can use this meta tag on the old domain to avoid dup content penalty

<meta name="ROBOTS" content="NOINDEX">

Code (markup):

 

Ii removed the files from old domain, leaving only this redirection.

How i should do it proper? I thought thats the proper way of 301 redirect.

 

yes. It looks ok.

By the way, keeping the files is irelevant, as long as the redirect is in place.

 

In the Google toolbar it shows n/a PageRank, it is ok? Shouldn't it be the PR from redirected page?

 

Its OK, in next update you will get the new updated PR.

 

Google consider WWW and non-WWW version of domains as two independent websites and index them separate, thus creating a duplicate website problem.

just u have selected a highest pr website both www and non www version
and then redirect 301.
