`ad_network_type` segmentation used without additional conversion related segmentation like `conversion_action` results in hiding some conversions.
SELECT metrics.all_conversions, segments.device FROM ad_group_ad WHERE customer.id = 'HIDDEN' Sum of "all_conversions" metrics from all rows: 225963. SELECT metrics.all_conversions, segments.device, segments.conversion_action FROM ad_group_ad WHERE customer.id = 'HIDDEN' Sum of "all_conversions" metrics from all rows: 225963. SELECT metrics.all_conversions, segments.ad_network_type FROM ad_group_ad WHERE customer.id = 'HIDDEN' Sum of "all_conversions" metrics from all rows: *225959* (invalid number). SELECT metrics.all_conversions, segments.ad_network_type, segments.conversion_action FROM ad_group_ad WHERE customer.id = 'HIDDEN' Sum of "all_conversions" metrics from all rows: 225963. I would expect the sum of "all_conversions" metrics from all rows to always be equal (regardless of segmentation used). -- -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog: https://googleadsdeveloper.blogspot.com/ =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API and Google Ads API Forum" group.
