false positive penalty.
Can you explain - I've not heard of this phrase.
Do you have a true 404 response set up for bogus URLs, or does every not found url 301
As far as i know all old URL's were either 404'd or 301'd only. What concerns me is that some old site's had all the their URL's either 301'd to the root domain , or in some redirected domains, to a subdirectory URL . I'll have it checked out though.
