Welcome to the Q&A Forum

So I know have seen how my websites have taken a nose dive from the google farmer update most likely with traffic significantly hit.  Example site is callcatalog.com.  What recommendations are there to deal with the new world order?  How can we look at optimizing, changing, modifying our process to improve rankings and traffic?

Callcatalog.com is a complaint directory for phone numbers.  People post information on the phone calls they get.  Since there are many many phone numbers, obviously people haven't posted information on ALL of the phone numbers, THUS I have many phone numbers with zero content.  SEOMoz is telling me that pages with zero content looks like duplicate content with each other.. The only difference between two pages that have zero coments is the title and phone number embedded in the page.  For example, http://www.callcatalog.com/phones/view/413-563-3263 is a page that has zero comments.. I don't want to remove these zero comment phone number pages from the directory since many people find the pages via a phone number search. Here's my question:  what can I do to make google / seomoz think that thexe zero comment pages is not dupliicate content?
