Found something strange in Google Adwords? To pinpoint the issue, we'll need to explore your data. This can be done by exporting your Adwords data to a CSV file.
This will build a CSV file containing all information stored in your current Google AdWords account. At this point, please submit a support ticket (be sure to attach this file!) so we can take a closer look at your data. If the file is too large, share it with the Magento BI team via Dropbox or Google Drive.
For more information about Google AdWords CSV file exports, please refer to the official Google AdWords documentation here.
