You need to enable the Ad review center before you can start to review your ads.
To enable the Ad review center, follow these steps:
- Sign in to your AdMob account at https://admob.google.com.
- Click Blocking controls in the sidebar.
- Click Go to Ad Review Center.
- Click Enable.
Your Ad review center is now enabled. You can start reviewing ads in about an hour.
Note: At first, you'll only see ads that have shown on your site since the Ad review center was enabled. Over the next day or two, more ads will appear for you to review.
