GoDaddy has long placed ads on registered domains that customers have parked at GoDaddy. Now, GoDaddy is allowing webmasters to sign up for a paid monthly subscription to CashParking, that would see webmasters get a share of the profits made from all clicks on the parked domain.
The unique aspect of GoDaddy's program is that they are giving the domain parking service to those who may only have a small number of domains in their portfolios, while Google normally only accepts those into the program with domain portfolios numbering hundreds of thousands of page views per month.
GoDaddy's domain parking program is serviced by Google's AdSense for Domains program (formerly known as Domain Park), with ads being displayed with the Google AdWords program. And example of the GoDaddy landing page can be found at fishinginia.com
