Not too long ago, marketers and search engine optimisers used to avidly watch out for something called the Google Dance. As the World Wide Web expands constantly with new websites, and pages are added and some deleted, Google's famed search algorithm constantly adjusts its ranking. It crawls through these pages, gauges their relevance, sniffs out frauds, and modifies how sites appear on its page. This is what is called the Google Dance.
At the heart of this game is the fact that Search is not Microsoft's main business - it has market leading, super-profitable growth businesses in enterprise software, the cloud and gaming.
