Does some one know i still have problems to get my site index by search engine without www. The case is my site ranked on msn, and i added site once again with www. so it has dropped. But pages that still have not get indexed with www. are getting visitors from msn.
I have the same issue with a site. But you are getting visitors so it really doesnt mather. Be sure to use .htaccess and you are safe. RewriteEngine on RewriteCond %{HTTP_HOST} ^yourdomain\.com RewriteRule ^(.*)$ http://www.yourdomain.com/$1 [R=permanent,L]
This needs to be done at the time of launch of the site, not once you start ranking withany one of the versions.
No, you dont have to do it at the time of launch of the site, you can do this anytime, eventually the search engines will learn that it is the same site.
