Welcome to the Q&A Forum

I have been using SEOmoz to clear errors from a site. There
were over 10,000 errors to start with. Most of these were duplicate content, duplicate titles and too many links on a page. Most of the duplicate errors have now been
cleared. This has been done in two weeks (down to around 3000 errors now). But instead of improving my rankings, pages that were on the second page of Google have started to drop out of the listings altogether. The pages that are dropping out
are not related to the duplicate problems and get A grades when I run SEOmoz
page reports. Can you clean up too much too quickly or is there likely to be another reason for it?
