I had 6 sites on page 1 and 2 in top position. None of my sites are showing until last page. This happened overnight and wondering if anyone else is having this issue.
The following things could of happened: 1) Google Dance. 2) Built too many links. 3) Some of your links got lost value. But about the whole Google changed something, I have also noticed some kind of update.
The opposite happened to me... pages that were previously down are back to top rankings again today. Looks like they did a big update
Google has slowly been testing out their new "Caffeine Update" for the past couple weeks to a month. Its possible that is they expanded where they are rolling it out and the result is what you are seeing.
