What is Google Dance

Google is always come up with new updates and information. I was going through one of its concept which I like the most and was found very interesting and want to share with you all, so, Here in this post, I come up with Google Dance. Now firstly, you should know what really Google Dance means.

It is assumed that during the month, Google update their index by recalculating the page rank of each of the Web pages crawled by him. The update process is initiated every 30 days or so, although on some occasions there have been more than 30 days between updates. The time period during these updates is actually called the “Google Dance”.

Now come to the significance of Google Dance, due to the dynamic nature of page rank, these calculations for updating index is performed about 40 times, as the index database is very large so the calculations takes several days to complete this process. During this time period the results for index might fluctuate. So to minimize these fluctuations Google Dance comes into picture.
Google has two other searchable servers apart from Google.com.These are www2.google.com and www3.google.com considered as test servers for Google other than google.com (which is the main server).Most of the dance these servers are same, but during the dance they are different .For most of dance, the ranking that can be seen on www2 and www3 are the new rankings that will transfer to main server i.e.www.google.com when the dance is over. The reason people are interested in the dance is you can get an idea of your future Google keyword ranking by checking the other Google servers as they are updated before the main server google.com. If you have added new pages and want to know if they have been indexed, checking Google data centers during the dance will tell you.

Now how can you check the new page rank during Google dance? Google has 12 datacenters all over the web, with unique IPs and any datacenter can provide the toolbar page rank for any of the webpage? During the dance these datacenters update one by one. At the beginning of the dance all datacenters return to the same, current page rank for a given web page but as the dance progresses they are updated one by one, to the new page rank value. By checking each of the data center during dance the new page rank spreads over the centers. If the page rank for a particular webpage is not changed, all the data centers will show the same values.
