How to measure the Google AdSense payout rate

• Set up an ad for an obscure fictional product such as a "frilltribbler"
  
• Create a web page dedicated to that product and nothing else - make sure you put your product name in the metatags, the page title and the headings and then make up some wording about the product in the body of the page
  
• Sign up that page for AdSense and create a separate channel to monitor earnings off that page
  
• Create an AdWords ad for that product and select content-targeting for the AdGroup you place the ad in
  
• Wait for your ad to appear on your site
  
• Visit the page and click on your ad
  
• Check your AdSense earnings for that ad
  
• Check your AdWords account for that ad
  
• Compare the two
