Revenews reports that the new Google policy on affiliates has a gaping loophole. The policy states that Google will allow only one ad per destination URL, rather than domain, which means that affiliate arbitragers could in practice get around it by creating multiple destination URLs. If Google further restricts the policy to allow only one ad per domain, then it will have come a long way toward reflecting the long-term Overture policy, which tends to grant brands much more control over how their brands appear in ads.
