Part of the algorithm designed by Google to give fresh content and new sites a chance to get noticed and build attention on the Internet can lead to some new webmasters ranking pretty well for brand new sites. These sites will often then jump about in the rankings before settling at a new level. This period of uncertainty is often called ‘dancing’ about in the rankings or the Google Dance.
Sometimes after a campaign of SEO or some new viral campaign driving lots of traffic to a site a similar move in the rankings before settling to a new ‘long term’ level can occur. This is also often referred to as a Google Dance. It can be confusing for webmasters as they can be unsure when or where it will end and if anything they are doing is having a positive or negative effect during this period.
