The 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.
To get started with this tool, please login to your AdSense account. You will find ARC in the ‘Competitive Ad Filter’ section located under the ‘AdSense Setup’ 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.
In order to maximize your revenue, we suggest that you keep the default setting to, ‘Run ads immediately.’ This will allow ads to run without delay while still allowing you to login and review the ads at a later time. By selecting the ‘Hold ads’ option, you could potentially decrease your revenue. This option will hold ads from displaying for 24 hours, thus limiting the number of advertisers' driving up your auction price.
You will then have the ability to approve or block a specific ad or advertiser in general. These settings can be changed at any time. Please keep in mind that blocking ads will remove them from the auction and could impact your revenue.
