I have my member and attachment pages currently blocked in the robots.txt file and Google is showing me that there are thousands of pages that are indexed, yet blocked in that file. I don't want these pages indexed at all because I believe they are behind my website's huge ranking drop because of Google Panda. I am not sure what the best way to deindex these pages is though. Should I unblock them and update the template code include the meta noindex or is there a better way to go about this? I want these pages out of the index and gone forever.
