Being one great program developed by Google, unfortunately the company doesn't disclose such information. Some speculate it to be around 70% to 80% but no one really knows, its one of life's mysteries as some say it is. One thing you can do is to participate in AdWords, Google’s program for advertisers and see how much others are paying for specific key words. Also, the better your key words are set at your website, the better content is directed to users and the better chances users are going to click on the ads as a general rule. I used the following formula (found on several places on the net) to build my expected revenue module: 1000 page views per day + 1% click through rate + 25 cents per click =$2.50 per day So build the above into an excel sheet, tweak it and use it to build your numbers up.
