iMedia Connection: How Accurate is Google AdWords?: "Having done everything Google asked of me -- by the book -- I waited a week for the numbers to cook. At the end of that time, Google Analytics told me I had 14 AdWord visits while the AdWords billing system itself claimed 59. My own software, InSite, also said 14 visits, the same count as Google Analytics.

On other metrics, such as traffic from native listings, or other sites, InSite matched Google Analytics to within three percent. I think this validates the accuracy of both InSite and Google Analytics. So the system that Google told me to use was telling me that Google AdWords were over-counting. I now had two different products telling me that Google AdWords was over-charging, and by a significant margin."
