Google Dance
[!] Since November 2003 (Florida update), Google has not performed any "dance". From that moment on, ranking changes have occurred continuously in the search engine. Everything seems to indicate that the once-famous dances will not happen again. I keep this section because of the historical importance these "dances" once had.
Once a month (approximately), Google recalculates the PageRank of
each web page and therefore updates search results.
The Google Dance is the period between the start and the end of this
update. It usually lasts around 4 days, and during that time different
results can be obtained from different Google servers: www.google.com,
www2.google.com and www3.google.com.
The best moment to publish pages on a website is during the Google Dance. If too much time passes between the end of this update and the publication of new content, the number of pages included in the next update is reduced.
This event used to occur roughly once a month.
