I'm at a lost here and hoping someone can provide some pointers. All of a sudden a site I manage has gone from about 1500 index pages to 90 and now is showing omitted results. I have looked at all the reasons for omitted results and none of them that I can seem to find point to why the site is showing omitted results. I have checked the google webmaster tool and it is not showing any errors, not showing duplicated content, and no crawl errors. All pages are unique and I have a robot text file telling google not crawl areas of the site. The only thing I have done in the last few weeks was write a few articles and manually submitted them to a few articles directories. I have done that before with other sites and never had the omitted results on any site before. This site is built using X cart.
