Google is the most popular search engine on the Internet and has quickly become a household name associated with Internet search. Google works by crawling sites on the Internet and forming associations on what pages are the most relevant. Search "spiders" go out and continuously crawl sites to make it possible to search for anything and get fairly up-to-date results.
The service became immensely popular because of its simplicity and speed. Google.com still takes you to a stark, white start page with a simple form to write in your search. In addition to an enter button, Google has also become somewhat famous for its eclectic "I'm feeling lucky" button, which takes users straight to the top search result's page, skipping the ads that usually associate the results--a move that costs the company hundreds of millions of dollars every year.
In addition to regular Web results, over the years Google has also added search options for pictures, videos, news, blogs, and more than a dozen other Google services.
