Get specific. Saying traffic is down 50% tells you nothing. Figuring out which pages no longer receive traffic is the first step. Evaluate them and compare them to pages that weren't affected. ARE they the nearly empty pages or not? If the drop is indeed sitewide start looking towards a possible manual action since, obviously, not all your answer pages are low content etc.
