Google to Kill Domain Testing

Google will stop monetizing all domains if they are less then five days old. This potential new policy change by Google could stop all Domain Tasting in its tracks. The Add Grace Period (AGP) is a time period when registrars can delete a domain at no cost, but in this time frame a registrant could register millions of these temporary domains and place Google Adsense for Domains on them. The result is the ability to produce millions of temporary websites that literally generate millions of dollars in income per week for Google. Domain tasting, for those not familiar with it, is the practice of registrants using the five-day grace period at the beginning of a domain registration to test the marketability of a domain name.
