Shop Ads Measurement
If you are looking for the Return On Ad Spend (ROAS) metric in the product level report and cannot find it, this article will help you understand why it is not available.
Ensure you have access to the product level report.
Verify that you are looking in the correct section of the report.
To troubleshoot a missing ROAS metric:
Understand the Definition: ROAS is defined as attributed Gross Revenue divided by ad Cost. Ad Costs could be billed based on impressions or clicks.
Check the Attribution Logic: The product level report is based on what the user eventually purchased, which may not match the products featured in the ads.
Review the Example: A user may click on an ad featuring Products A, B, and C but purchase Products B, C, and D. The products purchased are not entirely the same as those featured in the ad.
Note:
The product level report is not impacted if the ad group selected Showcase as the product source.
The product level report is not impacted if the ad group did not select a specific Shop as optimization scope.
The product level report is not impacted if a campaign has multiple ad groups that have more than one ad format (Video Shopping Ads, LIVE Shopping Ads, Product Shopping Ads).
