I own 7 e-commerce sites but one of them died in Google rankings on 7/22/2014, it was a successful site for 2 years previous to this day. It still ranks in Yahoo and Bing but not Google, we have had no warnings in WMT. We have hired 2 SEO companies to tell us that they see nothing wrong with the site. The site currently just generates money mostly from picture ads now. We disavowed any links that looked spammy back in October. All 7 of the sites run on the same format but do not sell the same items. I feel no matter what we do the site will never recover. Should I just kill it or does anybody have any suggestions?
