Google Dance
The Google Dance refers to when Google indexes are updated. This period of time often results in fluctuations in the index size and some noticeable changes in search engine result positions.
The term Google Dance was adopted as while an update is being processed the position of a website in Google seems to "dance" as it fluctuates. The fluctuation is due to each of Google's nine datacenters being updated out of sync - meaning for a time the results are different.
