Google recently launched a version 2.0 of their referrals program, also know as pay for action ads.
AdSenseAdvisor posted at a WebmasterWorld thread to clarify what Google publishers can and cannot do with these ads.
Yes, you can encourage people to click and view those ads. This is unlike Google AdSense's contextual product and only applies to the referrals (PPA) product.
But, you as the publisher of the site, cannot click on your own ads. You can't click on the contextual ads and you can't click on the referral ads.
Publishers aren't allowed to click on their own live PPA ads, including both referrals 1.0 and 2.0, for any reason.
Unlike PPC ads, you are allowed to actively promote your referrals, but like PPC ads, clicking your own PPA ads or creating your own conversions is prohibited.
