To maintain dominance in the search engine optimization market, Google constantly researches and adjusts its algorithm to provide the best search results for users. Google makes small updates all the time and these updates have become known as the Google Dance. Major algorithm updates, which have a big impact on search results, happen far less frequently. These updates are usually targeted at a specific problem, usually an area that is allowing spam to rank well in the search results. Major algorithm updates have had such an impact on search results that Webmaster World decided to start naming the updates at SES in Boston in 2003. The first update to receive a name was called the Boston update.
