While Google provides advertising feeds to Sedo and GoDaddy, it also offers its own domain parking program Adsense for Domains. It is integrated into conventional Adsense account and customers receive earnings directly from Google.
Adsense for Domains employs a one-page pay-per-click (PPC) monetization scheme. There is no organic SE traffic. Publishers are not allowed to drive traffic to the parked pages via online advertising. Redirection is prohibited.
There is an option to provide target keywords. Target keywords should be relevant and correlated with the subject of domain. Google reserves the right to ignore keywords provided by the customers. A maximum of 1500 domains are allowed per account. It is possible to change the look of the pages right from the Adsense account.
Bodis nameservers are as follows: ns1.googleghs.com, ns2.googleghs.com, ns3.googleghs.com, ns4.googleghs.com.
Approximate number of parked domains is 135K (August 2011).
