Does Google publish any page that gives a criteria they use for removing a
web site from their index? Recently our web site went from being in the
top five for many of the products we sell to not being listed anywhere, even
on the bottom of the Google search list. Apparently they know something
we don't. Definitely we didn't put any low quality links on our pages or
allow our site (knowingly anyway) to be linked from other low quality sites.
I'm at a loss to understand what happened and would appreciate guidance.
