The name "Google Dance" was in the past used to describe the period that a major index update of the Google search engine are being implemented. These major Google index update occured on average every 36 days or 10 times per year. It was easiest be identified by significant changes in search results, and by an updating of Google's cache of all indexed pages. These changes would be evident from one minute to the next. But the update did not proceed as a switch from one index to another like the flip of a switch. In fact, it took several days to finish the complete update of the index.
