I had a website ranked 7 & 8 postioned in Big G's search result for a quite a long time like 2 and half months, Suddenly my website dissapeared, I can't find it anywhere. It was a product base micro site ( 1 page). But when I check in Webmaster tool section it shows that the site is still on position 7 & 8. I don' t get it? What is happening?
