Is the Google-Dance Dead? Read below to find out!
Once a month, usually during the 3rd or 4th week, Google has a major shift in it’s rankings. This is when Google “tweaks” is algorithm, and when it updates each sites PageRank and Back Links.
During the month there will be minor changes in rankings. This is called ‘Everflux”. But only about once per month does Google Dance, updating the back links and the PageRank. The dance usually lasts about 3-5 days. During these days the Google Results will vary widely.
The Google Spider is called Googlebot. Most sites are revisited by Googlebot only around the Google-Dance time.
Here is how Googlebot works. The first time it finds your site it may visit it every few days to see if the content changes. The theory being that if your site is constantly changing, then the Googlebot will continue to return on a daily basis. But, if the Google bot finds your site and indexes it, and then returns to the site every week and the site has not changed then Google will be apt to put you on the “monthly dance” schedule.
The Google-Dance usually goes on for 2-5 days. During these days results on Google tend to change by the minute. After the Google-Dance is over each site will have been adjusted for PageRank and Back Links.
**Since August (the last Google-Dance), Google has converted their spiders/Googlebot to update sites much more frequently, than once a month. Sometimes as much as twice a day! This is even more reason to keep your sites up-to-date and change your material/copy frequently. Those sites that Do NOT have constantly changing information, will be updated by Google every month or so.

Great site to hear about the “Google Dance”
and chat about Google & other SE’s!!The best time to put new pages online is during the Google-Dance. If you let too much time lapse between the completion of the update, and the publication of new content, you may reduce the amount of new content that will be included in the next update.
Many webmasters think that, during the Google Dance, Google is in some way able to control if a server with the new index or a server with an old index responds to a search query. But, since Google’s index is inverse, this would be very complicated.
The name “Google Dance” is often used to describe the index update of the Google search engine. Google’s index update occurs on average once per month. It can be identified by significant movement in search results and especially by Google’s cache of all indexed pages reflecting the status of Google’s last spidering. But the update does not proceed as a switch from one index to another at one point in time. In fact, it takes several days to complete the index update. During this period, the old and the new index alternate on www.google.com. At an early stage, the results from the new index occur sporadically. But later on, they appear more frequently. Google dances.
The Google Dance Test Domains www2 and www3 – The begin of a Google Dance can always be watched at the test domains www2.google.com and www3.google.com. Those domains normally have stable DNS records which make the domains resolve to only one (often the same) IP address. Before the Google Dance begins, at least one of the test domains is assigned the IP address of the data center that receives the new index first.
Building up a completely new index once per month can cause quite some trouble. After all, Google has to spider some billion documents an then to process many TeraBytes of data. Therefore, testing the new index is inevitable. Of course, the folks at Google don’t need the test domains themselves. Most certainly, they have many options to check a new index internally, but they do not have a lot of time to conduct the tests.
So, the reason for having www2 and www3 is rather to show the new index to webmasters which are interested in their upcoming rankings. Many of these webmasters discuss the new index at the Google forums out on the web. These discussions can be observed by Google employees. At that time, the general public cannot see the new index yet, because the DNS records for www.google.com normally do not point to the IP address of the data center that is updated first when the update begins.
WHAT DOES THIS ALL MEAN?????
Simply, keep your content FRESH and UP-TO-DATE! … Not just once a month, but constantly!!
