Google announced upcoming changes to the way 3rd-party partners provide reports and information about AdWords to their clients. "If you work with another company to manage your AdWords campaigns, you should be able to find out how much of your advertising budget (cost) was spent on AdWords, how many times your ads appeared (impressions) and how many times users clicked on your ads (clicks). We'll include these requirements in our legal terms and agreements starting in February 2011," stated Google.
Almost all our 3rd-party partners are already providing advertisers with this basic information today, but for those who'll need to make changes to their systems, we're offering six months so that there's plenty of time to prepare to meet these new requirements.
Also, launched AdWords Policy Change Log in Help Center. This new site makes it easier for you to stay informed about upcoming AdWords ad policy changes. "If we anticipate that your account will be directly affected by an upcoming policy change, we'll still email you a service announcement as necessary to make sure you're aware of the change," stated Google.
