Google.com earns most of its revenue by allowing other website owners to advertise on their search result pages. All this is managed through a program they call AdWords. You can earn a share of the revenue that Google earns from AdWords by placing these same text ads on your site. This program is called AdSense.
Website owners pay Google to display their ads and are charged a predetermined amount every time their ad gets clicked. With the AdSense program, you will display these same text ads on your site just like Google and get paid for it as well.
To join this program, you just need a website. Apply for free at http://www.google.com/adsense.
