The search giant today unveiled its 2011 Economic Impact report, and said that its search and advertising tools, including AdWords and AdSense, drove $80 billion in economic activity across the U.S. last year. The company was able to reach that figure with help from “1.8 million businesses, Web site publishers, and non-profits across the U.S.”

In order to arrive at that figure, Google used some fancy math. The company estimates that businesses that use AdWords make $2 in revenue for every $1 they spend on the advertising platform. In addition, the company assumed that a business will receive five clicks in search results for every one click on their ads.
