â€œThe Ad Review Center (ARC) will give you more transparency and control by enabling you to approve or disapprove placement targeted ad creatives before they appear in your posts.â€
â€œTo get started with this tool, please login to your AdSense account. You will find ARC in the â€˜Competitive Ad Filterâ€™ section located under the â€˜AdSense Setupâ€™ tab. If you are using your AdSense account for other products- content, mobile, or video- please make sure to select the Client-ID starting with ca-feed-pub.â€ – Barbara Bochner, Google Publisher Solutions Team
