The Google policy on Double Serving will be revised around mid-May 2012. This policy update will reinforce key double serving criteria to prevent advertisers from running ads for the same or similar businesses across multiple accounts triggered by the same or similar keywords. We made this decision to ensure the diversity of ads running on Google. After the updated policy goes into effect, the policy description will be updated to reflect this change.
