Google Dance
 

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. What is your opinion on Google�s Index update? Please share your views.

The update process servers Google searching the web, which usually takes place once a month. Webmasters often check the placement of your web pages after the Dance on Google to see if rank higher or lower than before.
