Reporting Service
The adCenter Reporting service provides operations that you use to request predefined reports. The reports provide detailed statistics about accounts, campaigns, and ad groups. The information can help you track finances, measure ad performance, and adjust settings to optimize your budget or campaign.
For example, you can use the keyword performance report to see which keywords are generating traffic and which are not. For a list of reports that you can request, see Report Types. For information about how to request and download a report, see Request and Download a Report.
