CampaignChangeData and AdGroupChangeData

[Marcin Gdak]

Hi,

I am thinking how I can what type of the criterion get to know was changed, and what advertisement.
I tried to get CriteriaType from the CriterionPerformance report. In the result I got information that all CriterionType are "Keyword", either than a truth isn't.  In my opinion types "LOCATION" should still be.

Why I am not getting results from the CriterionPerformance report, when I am checking of Criteria from CampaignChangeData?

Thanks,
Marcin

Hello,

You could get the changed criteria and changed Ads from AdGroupChangeData. The CampaignChangeData contains AdGroupChangeData. You could get CampaignChangeData by using CustomerSyncService. Check out our GetAccountChanges Java example code of client library. 

The CRITERIA_PERFORMANCE_REPORT is a Single attribution report. This means for every impression, AdWords will pick *one* criterion that is the most relevant criterion(in your case Keyword) for that impression, and show it in the report. Even though you have the LOCATION criteria, that probably is not the most relevant criteria that triggered the Ad, hence it doesn't show up in that report.
