So we have Drupal up and running. The only thing now is, why is Google Webmaster Tools showing that Drupal is serving up duplicate content for Title and Description for all:

1. articles created with an alias
- ie. domain.com/node-name and domain.com/article.html

2. nodes imported into Drupal that redirect to an outside URL
ie. domain/node-name redirected to domain2.com/name.html

Any ideas on how to fix this?
