Google is a fully automated search engine that employs robots known as "spiders" to crawl the web and find sites for inclusion in the Google index. Google currently looks at more than 8 billion URLs during such crawls. The crawl process is algorithmic. Computer programs determine which sites to crawl, how often, and how many pages to fetch and index from each site.
Certain types of information receive special search formatting treatment to provide the features listed above, such as stock quotes, file type, special numerical searches, dictionary, maps, weather, and others detailed by the Google Help Center.
