Beginning on May 5, 2008, the AdWords trademark policy for the UK and Ireland will change. The new policy will be aligned with the current one established in the United States and Canada.
AdWords users in the UK and Ireland will be able to bid on keywords that contain trademarked words, but will not be able to include trademarked names in their ad text. Until now, accounts in those countries could not bid on trademarked terms.
The U.S. policy has sparked controversy in the courts, which can't seem to agree on the use of trademark in PPC bidding. The change comes in the wake of recent reports that clicks on Google paid search results have been declining.
