re indexing any website on google

hello,
i have hundreds of pages indexed on google with "www" before the link but thousands of pages without "www" .. and this thing has broken my PR ..
i am going to remove those pages from google with "www." .. so will google again reindex those pages without "www. ??

 

Use rel=canonical to tell Google that your www pages are the same as non-www. You won't lose any PR then.

 

Just redirect (in htaccess)www to non www

 

Yeah, 301 redirect also helps. Actually, I would start from the redirect, then go for the canonical tag.

 

Add your site to Google Webmaster Tools and select the URL variant you prefer Google to consider.

 

Yes, use the google webmaster account to manage this. It is more effective.

 

you can do a 301 redirect form non-www version of the url to www version fo the url

 

Thanks for the help ....

 

Which one are better www. or non www. ? Or they are the same?

 

Put this code in your .htaccess which can be found in the rrot directory:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www.yourdomain.com [NC]
RewriteRule ^(.*)$ http://yourdomain.com/$1 [L,R=301]
</IfModule>

Code (markup):

Also, use Google webmaster tools to choose the preferred domain as non-www version of your site.

And the use of Canonical link element will also help;
