Inconsistent click counts between GEO_PERFORMANCE_REPORT and CAMPAIGN_PERFORMANCE_REPORT

[Justin Coon]

Can anyone explain the discrepancy between click counts in these two reports? The API has the same discrepancy as the UI -

Thanks

Hi Justin, 

In GEO_PERFORMANCE_REPORT If you request both IsTargetingLocation values in your predicate and either do not limit by LocationType or request both LocationType values in your predicate, then the same impression's statistics may appear in multiple rows of the report. Therefore, statistic totals from your report could be much higher than totals from other reports such as the CAMPAIGN_PERFORMANCE_REPORT. If this does not explain the discrepancy, could you reply privately to author and share your client customer id and the report definition? 

Thanks,

Hi Justin, 

I see that in some cases the stats in User Location report and the Campaign Performance report does not match in the UI as well. Since this is a product level question than one specific to the API, could you please post the question on the Advertisers community forum? The product experts there are better equipped to address this question.
