Everybody is familiar with Google now days and their by using Google every time they want to have, to get the things and all the stuffs that are new, latest and updated information. Google is one of a kind, all the concepts of Google are very rich, 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 is all about.
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 comes 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). 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.
Whilst nobody outside of “Google” truly seems to know the purpose of the www2 & www3 servers, many people have come to the assumption that they are test servers. During the update, which takes several days, the 3 Google servers display different results. Whilst the results vary from server to server, they are said to be “dancing”, hence the name “Google Dance”.
Now how can we 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. During the dance, the results from www2 and www3 will sometimes show on the www server, but only briefly. Also, new results on www2 and www3 can disappear for short periods. At the end of the dance, the results on www will match those on www2 and www3. 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.
