Are you in Google Supplemetal Hell?
Then don’t worry – we have it from the horses mouth (Google Spam Guru Matt Cutts) that it’s not something you need to worry about as it can be fixed.
As a reminder, supplemental results aren’t something to be afraid of; I have got pages from my site in the supplemental results, for example. A complete software rewrite of the infrastructure for supplemental results launched in Summer 2005, and the supplemental results continue to get fresher. Having urls in the supplemental results doesn’t mean that you have some sort of penalty at all; the main determinant of whether a url is in our main web index or in the supplemental index is PageRank.
If you used to have pages in our main web index and now they’re in the supplemental results, a good hypothesis is that we might not be counting links to your pages with the same weight as we have in the past. The approach I’d recommend in that case is to use solid white-hat (ethical) SEO to get high-quality links (e.g. editorially given by other sites on the basis of merit).

“It can also be the case that links that used to carry more weight for a website might not be counting as much.”
“As I said in January: The approach I’d recommend in that case is to use solid white-hat (ethcial) SEO to get high-quality links (e.g. editorially given by other sites on the basis of merit).
