• Its not an index of bad or penalized websites but its the index of sites that not have the required importance to be listed in main index.

• Supplemental results are part of Google’s auxiliary index (main results are drawn from the main index) and pages, which appear on the supplemental listing, have “fewer restrictions” than those that appear on the main results page.

• The supplemental is simply a new Google experiment. As you know we're always trying new and different ways to provide high quality search results," said Google spokesperson Nate Tyler.
