In this video, we'll take a look at how to configure the Redirect module to automatically take care of our "duplicate content" issue.
We've just discovered that because we have URL aliases setup, our site may be penalized by search engines for having "Duplicate Content" even though we don't actually have any. By installing the Redirect module we can have this automatically taken care of for us. You can find the Redirect module at drupal.org/project/redirect.
