Supposedly launched about a month ago, Google announced their new Hummingbird algorithm on Sept 26, 2013. In a nutshell, Hummingbird focuses on the meaning behind a particular search quires as opposed to the individual words themselves. Called: “Conversational Search” – Google will attempt to return the most relevant web pages to what people search for rather than simply finding pages that match the words in the search. Search Engine Land did an excellent post explaining the various nuances of the Hummingbird Algorithm, you can read that HERE.
