I recently had google WMT report on an increase in soft 404 pages. these were all search pages (example.com/search/page/211) and there were 211 of them. I have since then blocked all search pages in robots text and when i go into WMT and try fetch them they come up as "blocked". How ever these soft 404's have now stayed in the WMT for a few months. Do i just go and mark them as fixed or is there something else I should be doing?
thanks
