Discovery Campaigns ads missing in Adwords v201809

[Anthony Heikkinen]

For a query with Criterion I get less cost per campaign than without Criterion (CriterionId, CriterionType)

With CriterionId, CriterionType

SELECT Date, CampaignId, CampaignName, AccountCurrencyCode, AdGroupId, AdGroupName, Id, AdType, Headline, HeadlinePart1, HeadlinePart2, Description, Description1, Description2, CreativeFinalUrls, Device, AdNetworkType1, AdNetworkType2, Labels, CriterionId, CriterionType, ActiveViewImpressions, ActiveViewMeasurableCost, ActiveViewMeasurableImpressions, Engagements, GmailForwards, GmailSaves, GmailSecondaryClicks, Impressions, Interactions, Clicks, Cost, VideoViews, AbsoluteTopImpressionPercentage, TopImpressionPercentage, VideoQuartile100Rate, VideoQuartile75Rate, VideoQuartile50Rate, VideoQuartile25Rate FROM AD_PERFORMANCE_REPORT DURING 20190922,20190928

Without

SELECT Date, CampaignId, CampaignName, AccountCurrencyCode, AdGroupId, AdGroupName, Id, AdType, Headline, HeadlinePart1, HeadlinePart2, Description, Description1, Description2, CreativeFinalUrls, Device, AdNetworkType1, AdNetworkType2, Labels, ActiveViewImpressions, ActiveViewMeasurableCost, ActiveViewMeasurableImpressions, Engagements, GmailForwards, GmailSaves, GmailSecondaryClicks, Impressions, Interactions, Clicks, Cost, VideoViews, AbsoluteTopImpressionPercentage, TopImpressionPercentage, VideoQuartile100Rate, VideoQuartile75Rate, VideoQuartile50Rate, VideoQuartile25Rate FROM AD_PERFORMANCE_REPORT DURING 20190922,20190928

When looking at the Ad Type dimension I do not get any clues either how they were served.

What could be the reason for less cost for a discovery campaign?

Hi Anthony,

The difference in your cost per campaign value is likely because CriterionID and CriterionType are both segmentations of the AdPerformanceReport. Please see this guide on segmentation. Since the ads are getting segmented differently in the two reports, this will cause the values to differ.

Hi Anthony, 
Thank you for a quick reply.

Which rows are being segmented away? Could you elaborate on how the segmentation works in this case?

With best regards
Anthony

Hi Anthony,

For the report without criterion segmentation, each row will show an ad and the total cost for that ad. When you add the segmentation, each row will show an ad, a specific criterion for that ad, and the cost associated just with that individual criterion of the ad.
