How do I do it? I haven't been able to find any information on that. I don't want to use the pay-per-click advertising, just referrals. Do I need to sign up for Adwords first? Thanks...
I am not sure how you go about it. But, from what I've heard, I think Google selects the participants they want. Nonetheless, I would recommend shooting an email off to to see if they could tell you.
Right. But to figure out how, the AdSense folks would know for sure. Again, I don't think you go through AdWords to do it. I see no option there for this.
why not send an email to the adwords team instead of the adsense team? might get a faster response. https://adwords.google.com/support/bin/request.py?hl=en_US&ctx=foot
