My site, which has always #1 in the top key word searches--vanishes completely every 12 days!. The site is #1 because I have been around forever and am popular in a very specialized narrow area. Then after 10 days exactly, I return to Google to the first spot--isn't that why Google went 7 folds in the stock market?, because they bounce us off--poor little mom and pop's operations who are then forced to advertise on Adwords?--OBVIOUSLY YES!
