Our mission is to organize all of the world's information so everyone can access it and use it. There are thousands, sometimes even millions, of websites that provide useful information every time you search. Google's search engine determines which results to show you before you type. It is guided by your commitment to provide the best information. Google organizes information about websites in its Search index even before you start searching. The index works in a similar way to a library but contains more information than all the libraries around the world. Google's Search algorithms scan through hundreds of millions of pages in our Search index in a fraction of seconds to find the most relevant and useful results for your search terms. Google offers many formats to help you quickly find what you are looking for. We are constantly improving the way we present information, whether it's in a map with directions or images and videos.
