Google has made it easier to understand your imported ads cost data in Google Analytics.
You can now get insights into your imported cost data even if there was no matching record for the required dimensions.
In an effort to reduce friction and increase the usefulness of your imported cost data, Google has changed how Google Analytics handles unmatched imported cost data.
Google Analytics will now report your cost, impressions and/or clicks on any combination of the imported required dimensions.
This change gives you a more complete and accurate view of your advertising performance, leading to better informed decisions and more effective campaign optimization.
