It's very shocking how Google ranks pages.
MasterofPuppets may have hit the nail on the head. Your site may be algorithmically penalized. These days it appears that penalties take precedence over quality and any new pages you post on your domain may be automatically demoted as a result - regardless of the quality, depth and effort you put into these pages.
