Thank you for your input. We remain lost on all of this. I guess the only option we have is to shut the domain name down, get a new one, and start over. It is a shame as we have been using that domain for years and have enjoyed page 1 rankings for years. Our organic traffic has dropped from about 1000 per day to as little as 1... yes 1.
As have asked SEO companies, staff, even Adwords who did go out of their way to see what is happening with no solution.
I guess Google is not trustworthy... and a company ought not to waste 1 red cent on SEO as in a twinkling of an eye... they, Google, can toss you under the bus.
