Hi, a couple key pages for my clients website got removed from google (typed the page address but none came out). Other none key pages are still in the google search. Can anyone advice a quick checklist to find out what's wrong, and what I should go about fixing this? Thank you.
Also note that Google is currently rolling out their new infrastructure, Big Daddy, and there has apparently been a problem -- which they are now in the process of fixing (we all hope). See Big puzzle, number of pages indexed drops quickly [webmasterworld.com] and several other long threads about the "Supplemental Club", "Big Daddy" and "Data Centers Watch".
