To increase transparency for our advertisers and retailers, we have updated the Shopping ads Policy Center and free listings Policy Center to better explain our policies and how we enforce them. In addition, we launched a clarification of the YouTube Shopping ads requirements and Demand Gen product ads format requirements to ensure retailers can better understand why their ads may not be serving and how best to resolve the issues.
We've also updated the Google Shopping Help pages for Recommendations & personalization and How Google Shopping Works to better explain how our ranking works.
