I am looking for case studies, or examples of pages or sites being penalized for Doorway pages http://googlewebmastercentral.blogspot.com/2015/03/an-update-on-doorway-pages.html
My site has a footer full of them, from the prior web-dev team, and I``m looking for compelling arguments to get rid of them. I`ve seen the links and writing from a range of credible parties, I`m looking specifically for examples where they have done harm.
