Just found a way to check which pages of a website are in Google’s supplemental index. Might be handy because if your pages are in the supplemental index, that explains why that don’t show up in the normal results.
For example, see how many pages of digg.com are in the supplemental index:
http://www.google.com/search?q=site%3Awww.digg.com%2F+***
So, how does it work? Just perform this query: ” site:www.domain.com/ *** “
