Nick, I know how you feel as I'm there now. I've been in tears trying to figure out what to do. Thankfully I have repeat customers which are at least keeping the lights on while I figure out what to do. I can't see it being the Disavow tool in your case. I have read elsewhere Google has wiped out some big link networks, could it be that? Personally I'm not worried about Google, I've updated everypage, removed loads of others & have concentrated on customers. It's hard as in the UK Google IS the Internet but thus far I've seen no change, positive or negative. I figured I had nothing to lose, Google pushed me into this corner so I either go down or at least go down fighting. At least with the latter I know I did eveything I could have done. When did you fisrt notice the traffic hit? Are you ecom?
