Different data for www and no-www in Google Webmasters Tools

Question

My Webmasters Tools home page contains example.com and www.example.com in the sites section.

There is a rewrite rule (301 redirect) on my server that redirects all requests from www.example.com to example.com.

Now I am worried why dashboard pages for example.com and www.example.com show different data? These pages show different keywords and different amount of links to my site.

Is it normal? Is there any way to "merge" collected data? Or maybe there is a way to make Google treat example.com and www.example.com as one site (as it really is)?

Answer 1

Under Site Configuration > Settings, there is an option for preferred domain. Select the one you want and allow Google some time to transfer all your data to the preferred profile.

Answer 2

Did you set the preferred domain in your Webmaster Account? It can be found under settings.
