Google Adwords Referral
Adwords Referral button is now available together with the Adsense Referral. This is what Google says
We’re excited to announce that now, in addition to AdSense and Firefox, you can refer users to AdWords in countries and languages where AdSense for content is available. You’ll earn $20 each time one of the advertisers you’ve referred spends at least $100 with AdWords. To get started, choose ‘Referrals’ on your AdSense Setup tab and look for the AdWords sub-tab.
