Google Dance

Since Google is the number one search engine in the world, every time it Indexes itself is a very important time for webmasters and affiliates. A Google Dance is the time period during which Google is updating its search engine indexes (of which it operates several) and during this time rankings can swing wildly up and down. This process usually takes place no more frequently than one time per month, and a website may climb or fall drastically over the course of a few days. Recently, Google seems to have smoothed out some of it's erratic behavior and now these Dances are far less nerve racking than they were several years ago.
