The question I have is relatively straightforward. Would Google penalize a website for potential violations on pages that contain no-index and no-follow meta tags?
A client of mine runs a photograph site and was forced to de-index the overwhelming majority of their site in the wake of Panda 4.0. At this time the only pages indexed are the main page and the category pages. Originally they had a mobile redirect advertisement on the main page. Mobile users would redirected to the App Store or an alternative website. While Google certainly frowns upon redirects of this sort, would it be acceptable on pages these no-index / no-follow pages given that Google should not be crawling / indexing these pages in the first place?
