A PR8 site I consult on
Are you an SEO consultant or another type of consulant?
You really are not providing enough information to get back good feedback.
-Have the backlinks changed?
-Did they do any link development?
-Do they sell/buy links?
-Have you checked to see if the traffic loss is due only to a drop in Google referrals?
-Have you scanned for malware or signs of hacking?
-Have you checked to see if another site stole content?
-Are there any 302 or 301 issues?
-Have you checked for messages in WMT?
I could go on and probably list over 100 possible issues. If you want a better response please do a little more research and then ask for insights. It sounds like you have many issues if you have been consistently losing traffic since the 2010 redesign. Good luck.
