About two weeks ago I noticed that only 22 of my pages were indexed by Google. This is waaaay down from my high of around 400 in July. When I go to my Google webmaster account on the main page it says i have submitted 175 pages to Google index and 174 have been approved. However when I go to the Google Index tab it shows a graph and says I currently have only 22 pages indexed. I only practice white hat SEO tactics and I have no critical errors/messages or Malware messages. I asked Google to crawl a bunch of my pages and submitted my homepage and all of its links as a starting point in the indexing process but I still do not see a change in the number of indexed pages, that was a week ago. Could this be caused by the Hummingbird update? How long should I wait to see if my pages are indexed before I should start panicking? A lot of my rankings for keywords have dropped drastically and I am starting to get really worried that I did something wrong, I have no idea what though. Any help would be much appreciated. Thanks.
