"Q: What domains are eligible for AdSense for domains? A: AdSense for domains can be used on any domain that adheres to Google’s policies.
Q: Is Google involved in the selection or registration of the domains in the AdSense for domains program? A: Google is not involved with the selection or registration of these domain names, and is not in a position to arbitrate trademark disputes between the registrants, our partners, and trademark owners. Accordingly, we encourage trademark owners to resolve their disputes directly with the registrants or registrars. As a courtesy to trademark owners, Google provides a simple publicly available complaint procedure and, once notified of a legitimate complaint against a specific domain, Google will no longer serve ads to that domain. For instructions on how to file a complaint, please refer to the Trademark Complaint Process page. Additionally, a copy of our publicly available trademark policy is available online.
Q: Where can I find more information about the AdSense for domains program? A: Please refer to our Help Center for more information. "
