Fluctuation of Google search result during the calculations that need to be performed about 40 times and several day due to Google’s fresh crawl called by Google Dance. Google has two other servers that can be used for searching. The search results on them also change during the monthly update and they are part of the Google dance.

For most of the dance, the rankings that can be seen on www2 and www3 are the new rankings that will transfer to www when the party dance is over. Even though the calculations are done about 40 times, the final rankings can be seen from very early on. This is because, during the first few iterations, the calculated figures merge to being close to their final figures.

During Busby SEO Challenge, we have not seen any invitation from Google to dance. It’s coming soon. Are you ready ?
