Google Dance is a term we refer here and elsewhere when the search engine results change dramatically where your site can go from #1 position to #20 position without any apparent reason and then comes back with a lets say stable position #3 or any position for that matter.

Ranking results "Dance". This happens basically because of repositioning of site rankings most probably due to new algorithms being implemented by the Search Engines.
