One of the biggest topics in SEO lately has been the filtering of pages from Google's index because of duplicate content. This applies not only to articles that are reprinted from site to site but also within your own site.

If there is more then one URL representing the same page (without a 301 redirect) you run the risk of triggering Google's duplicate content filter.

Drupal is an awesome content / web page system. The Taxonomy System (also know as categories) allows you to assign multiple terms to a single story. Automatic views will show you teasers of each story for each view.

If your stories are often tagged with the same terms however, the same teasers may be appearing on different views. If the same 10 stories appear under View A and View B then View A and B will have duplicate content.

There are several methods to ensure that you do not get caught in the duplciate content trap.

• Use the robots.txt to exclude one or both of the views
• Only display teasers on one of the views
• Delete the automatic view and create your own
• Do not display teasers on your front page

We recently dealt with this issue on www.exercise-equipment-review.org. Many of our articles referenced treadmills and elliptical trainers. We made the decision to remove teasers from our frontpage and to create custom views to our articles.
