The technique of purchasing cheap traffic and driving it to a landing page optimized for displaying expensive Adsense ads. Here’s a quick example to illustrate this further: Someone purchases inexpensive pay-per-click traffic centering around the keyword ‘inexpensive toys’ for a mere 7 cents per click. The ads in this campaign direct a user to a website (eg: expensivetoys.com) that displays Adsense ads targeting a more high-paying keyword such as ‘expensive toys’ for 7 dollars per click. If even a fraction of users landing on this site click on the ads, the owner stands to generate a reasonable profit, as he will have earned more than he had spent.
