Google запускает бета-тест Pay Per Action

Rather than paying for clicks or impressions, advertisers can choose to pay when a user makes a purchase, signs up for a newsletter, or completes any other clearly defined action that they choose... You can list as many action types as you wish, either by choosing from our pre-existing action types, or by entering your own... Once you've defined an action, you'll need to set up tracking on your website so that we can record each time a user completes the action on your site.
