The update of the Google index is often referred to as the Google dance. For several days when Google is updating their index to include new pages and update their algorithms, search results almost seem to take on a life of their own. High positioned sites have been known to drop into near obscurity while the lesser-judged sites suddenly find themselves careering towards dizzy heights in the rankings. While this phenomenon is usually relatively short lived, lasting only two or three days, many webmasters take it to be a sign of things to come during the next major update.
