I have a domain, say www.example.com which is redirected to a website built in Google Sites. I don't want different search engines treat example.com as a different site from www.example.com. How do I make a permanent link between the two? My domain is under GoDaddy.
EDIT
In Go Daddy, I have forwarding option set to Google site link.
Under CNAME, I have Google provided alias and directions.
1) Do a 301 redirect from one to the other. Here is the code you can place in an .htaccess file in your webroot (change your_domain.com to be your actual domain):
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.your_domain.com$
RewriteRule ^(.*)$ http://www.your_domain.com/$1 [R=301]
2) In Google Webmaster Tools you can set your preferred domain so Google knows which one you prefer.
You can also specify canonical URLs for pages on your site by putting an HTML <link> element with proper information in the page <head>.
For example:
<link rel="canonical" href="http://www.example.com/product.php?item=swedish-fish" />
See "Specify Your Canonical" at the Google Webmaster blog.
