Google has announced some upcoming changes to the way its third party partners provide reports and information about AdWords to their clients.

"In order to provide the best online marketing experience, we want to make sure that you understand how each dollar you invest in AdWords is performing," says Jason Shafton of Google's Inside AdWords Cew.

"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)," he adds.

These requirements will be included in Google's legal terms and agreement starting in February.

Google says that while most partners already provide advertisers with the proper information, some will need to make adjustments.

More info about the changes can be found in the AdWords Help Center.
