Negative values in Shopping Performance Report

[Adam Orczyk]

Hi,

Today we got a lot of negative values in Shopping Performance Report for many accounts, ex. (per row):

clicks='1' impressions='18' cost='-170000'
conversions='-1.0'
clicks='-1' impressions='21' cost='-10000'
impressions='-1' cost='0' conversions='0.0'
clicks='0' impressions='-2' cost='0'
clicks='1' impressions='239' cost='-280000'
clicks='-3' impressions='29' cost='-120000'

How to treat this kind of stats? Is it normal behavior or bug?

We're seeing the same thing in PRODUCT_PARTITION_REPORT. We have seen negative impressions and negative cost. We think this started happening recently.

This is the query we used:

SELECT CampaignId, AdGroupId, Id, AdGroupName, Impressions, Clicks, Cost, CpcBid, Conversions, ConversionValue, SearchImpressionShare, BenchmarkAverageMaxCpc, BenchmarkCtr, ProductGroup FROM PRODUCT_PARTITION_REPORT WHERE IsNegative=FALSE AND CampaignStatus=ENABLED AND AdGroupStatus=ENABLED  DURING LAST_30_DAYS

Hi Adam, 

Could you provide the complete report definition along with your clientCustomerId so I can take a look? 

MG, thank you for providing the report definition. Could you provide your clientCustomerId as well? 

Thanks,

I just sent you one example account. We've seen this for hundreds of accounts.

Thanks,

Hi All, 

Thank you for providing additional information. We are working on this issue as our top priority. We've found that stats for shopping product groups are incorrect for March 29 - 31. For now, if you use Product Partition Report or the Shopping Performance Report to download stats, then do not include the stats from these dates on any analysis. We will let you know once it is safe to pull stats for these dates.

Regards,

Hi All,

We've identified the source of the issue and are in the process of implementing a fix. Meanwhile, please do not include the stats from Product Partition Report and Shopping Performance Report for March 29 - 31 on any analysis. I'll update this thread when it's safe to pull these reports for those dates.
