Google is soon to offer advertisers the option to opt-out of the AdSense for Domains or DomainPark program. Advertisers can already choose for their adverts not to be shown when users first arrive at parking pages.
However this opt-out did not include the subsequent pages the user saw when they clicked a keyword term (usually shown as categories) or made a search. Now Google will make it easier for advertisers to opt-out of the entire parking page setup.
