An ad request is recorded every time a page or app makes a request for an ad from one of AdButler's servers. An impression is the result of AdButler returning an ad to that zone after it receives a request. The accuracy of logging impressions can be affected when serving 3rd party tags through AdButler. If AdButler has no way of confirming whether an ad was successfully delivered, an impression is still recorded.

Yes, AdButler can serve all types of 3rd party ad tag. You will need to confirm with your 3rd party supplier how to properly insert our tracking macros in order to accurately record statistics.
