This is a possible situation. Traffic sources may have different mechanism of our banner-click-counter (such as counting unique clicks only).
Another reason for the differences is that the traffic source and tracker may be in different time zones. In order we will be able to check, please inform us about what traffic source you are using, your campaign ID, and the period of time for which you view the statistics. It will also be necessary for you to indicate the number of visits in the traffic source and AdsBridge, as well as providing other statistics from your traffic source at the request of one of our support managers.
