Several pages from my site were dropped from the google rankings on Saturday. I started to investigate today, and I realised the keywords were still showing ranking for my site but much lower (page 9 instead of page 1) and the landing page was wrong. I thought, hmm looks like these landing pages have been de-indexed. So searched google for the urls and it seems they are still indexed, however the description for the page within the search result shows as noredicret (bot)' rather than the description you would normally get.Any ideas what this could mean ? Thanks.
