I have heard about the Term Google Dance. But i have no clear idea about that. Can any body tell me in detail.
Google Dance is term used when there is some fluctuations in your regular rankings. That may be up or down. But after some time it will be back to its original position.
Originally the term referred to frequent changes in google's serps due to differences among google's data centers. Now, it refers to changes in googles serps, in new sites, sites that just added a lot of new links, and changes when google is updating its algorithm or index.
The Google dance occurs when your site rankings keep fluctuating while Google is updating their servers.
The Google Dance is the different responses of the Google search engine at the same time identical searches. It is by through data exchange between different Google data centers completed the update process Search indexes caused. Again, this update process itself is sometimes referred to as the Google Dance. Google indexes just like any other search engine that Internet via automated web crawlers. For the sake of This load is spread over several independent Data centers, each with their own database index have. The database index is fixed at certain Intervals, but independently of each data center updated. This update can with a Time offset between the servers happen and therefore a given date at a more or less large difference in the indices of different server . Lead When user-side searches because different DNS resolution different Data center raised, and it is so despite identical queries different results from the various indices obtained.
It mean when a website in top position and by flactuation it's loss their position and will go down. But a short time it will came to their position. Some days ago it held with my website, but it is now in well posotion.
