The majority of Google’s revenue comes from advertising through Google owned and operated properties such as Google Search, Google Maps and more. In 2017, Google accounted for the majority of parent company Alphabet's revenues with 63.8 billion U.S. dollars in Google website revenues alone.
In 2016, over 71 percent of its revenue was generated on Google’s Sites, while around 17.4 percent came from advertising on Google’s network member’s websites and the remaining 11 percent came from licensing and other revenues. The revenues generated from Google’s network member’ websites include revenue from ads served through advertising programs such as AdSense for AdSearch for example. Other revenue include digital content products and apps sold through Google’s Play digital content distribution platform, as well as hardware include Chromecast devices and smartphones. With revenues projected to close in on 14 billion U.S. dollars in 2019, Google Play is an increasingly important contributor to Google’s bottom line, especially as smartphones sales and Google’s Android platform’s global market share increase. Geographically, the biggest single country share of Google’s revenue comes from the United States, but 44 percent of revenue come from the rest of the world and 9 percent from the United Kingdom.
As of May 2016, Alphabet ranks first among worldwide internet companies, with a market capitalization of 510 billion U.S. dollars.
