On the 1st of August 2007 Google officially removed the ability for users to view pages tagged as 'Supplemental' in the standard search results. Unfortunately, this was essential to the functionality of our Supplemental Results Tool and without the ability to view such results, our tool no longer works.
Matt Cutts from Google's Webspam department has a poll running on his blog asking for people to vote on features that they would like to see listed in Google's Webmaster Central. If you would like to see the supplemental results in Webmaster Central, vote here: Webmaster console features?.
We're sincerely sorry if you came here in search of a solution to this problem and hope that Matt brings the supplemental listings back.
