Google is clearly looking at pages more as part of a book instead of on an individual basis. I just checked again and I now have 2000+ errors. 1200 of those are pages I submitted a removal request for eons ago that has expired, they haven't existed in a LONG time, and the other 800 are bogus and all just improper or incomplete links from other sites.
SO - my site has ZERO pages missing right now yet Google thinks I have 2200+. Nice.
Is this impacting my search rankings? It had better not be.
