Google Webmaster Central

Google has renamed it's sitemap program. Now it is called Google Webmaster Central. Many new features added.

One is preferred domains option. With this you can specify your preferred domain name with or without www. i.e http://www.example.com or http://example.com.

This solve the canonical problem issues normally create lot of problems to webmasters.

Once it is set, it will take some time to reflect in serps because google has to re-crawl the site with the new setting. Anyway it is a nice move from Google's side because many websites have this kind of problems.
