The name "Google Dance" has often been used to describe the index update of the Google search engine. Google's index update occurred on average once per month. During an index update there was significant movement in search results and Google showed new backward links for pages. However, in mid-2003 Google started to update it's index continuously.

It appears that, still, there has to be an update of the complete index once in a while and during this time new backward links are shown. But, because of the continuous update, the effects on search results seem to be rather insignificant.

The Technical Background of the Google Dance

The Google search engine pulls its results from more than 10,000 servers which are simple Linux PCs that are used by Google for reasons of cost. Naturally, an index update cannot be proceeded on all those servers at the same time. One server after the other has to be updated with the new index.
