Google derives that estimate by looking at business activity in each of the U.S. states and then estimating the economic value provided by Google Search and AdWords, Google AdSense and Google Grants.
To estimate the economic impact of Google Search and AdWords, Google uses two assumptions. First, that businesses make an average of $2 in revenue for every $1 they spend on AdWords. Google Chief Economist Hal Varian, developed this estimate based on observed cost-per-click activity across a large sample of Google advertisers.
The second assumption is that businesses receive an average of 5 clicks on their search results for every 1 click on their ads.
