Statistics are updated hourly. Such updates are quite dynamic so the best option is to check your results at the end of the business day (mind EST time zone).
Our statistics might be different from yours as far as we only count impressions. If you have noticed a discrepancy between the statistics of visitors and impressions, please note that we do not count page-views as it is not the result of interaction with an ad.
An impression is counted only when the ad tag is fully loaded in the site's source code and visitor saw the ad.
If you believe that your statistics have not been updated or you have any questions, please contact our Support team via firstname.lastname@example.org.
