Supplemental Pages Check Tool
Supplemental pages: Pages Google considers either not current or not unique enough, but they still want to index and have a copy of them, so Google places these pages in the "Supplemental" index. This "Supplemental" index wont be updated (pages won't be spidered) nearly as much as the normal index.
EITHER Enter a url in the url field OR Enter a query to see the top 10 results for a keyword with the percentage of supplemental results for each domain that comes up.
