Clickfraud Killer, Pay-Per-Action From Google

Google introduces a Pay-Per-Action program in beta. I'm anxious!

Here are the highlights;

1. First, create an ad and define the action that you want a user to perform when they visit your site.
2. Then set the amount that you're willing to pay when this action is completed.
3. Finally, install conversion tracking code on your website so that we (Google) can verify when an action has been completed.
