Google Dance

What was the Google Dance?

From the summer of 2000 to the summer of 2003, Google updated its index about once a month, according to Matt Cutts, then a Google engineer. He wrote that the dance lasted six to eight days, because each data center in turn had to be taken out of rotation and loaded with an entirely new index. During such an update, several data centers held different versions of the index and took on the new data at different times. Depending on which server answered, the same query could return different results at the same moment. After the update, positions often settled in a new order.

In the summer of 2003, Cutts wrote, Google switched to an index that is updated incrementally every day or faster, and the effect lost much of its visibility. He also noted that terms such as Google Dance and index update are hardly used anymore. Google’s own documentation does not define the term.

Same name, other meanings

Google Dance was also the name of a party at Google headquarters held during the Search Engine Strategies conference in San Jose.

How is the term used today?

Some SEO sites use it loosely for short-term ranking swings of new or updated pages. Google’s ranking documentation does not use the term. Confirmed ranking updates are listed on the Google Search Status Dashboard.
