Google dance

Google Dance refers to the temporary fluctuation in website rankings that occurs when Google updates or recalculates its search index. During this period, search results may vary significantly from one day to another as Google processes new data and recalibrates ranking factors.
The term originated in the early 2000s, when Google’s index was updated in large batches. Websites often experienced unstable rankings for several days until the update was fully completed. Although modern indexing systems like Google Caffeine have minimized these fluctuations, smaller ranking shifts still happen during algorithm updates.

The Google Dance historically reflected Google’s batch-based indexing system, where changes to the web index were rolled out gradually across data centers. As new information was incorporated, ranking volatility increased temporarily until stabilization occurred.
Today, with continuous indexing and machine learning-driven updates, fluctuations still occur but are less predictable and more frequent. SEO professionals monitor Google Dance periods to assess the effects of algorithm updates, content changes, or backlink adjustments. Tools like Google Search Console and rank trackers help detect patterns during these transitional phases.

Example
A travel website noticed large ranking fluctuations during a Google Core Update. Instead of making immediate changes, the SEO team monitored results for two weeks until the algorithm stabilized, after which rankings returned to normal. This confirmed the changes were part of the Google Dance rather than a penalty.
