On your Sites page, you can build a list of your sites to use in AdSense. For example, if you want to show ads on a new site or set up site-level blocking rules, you first need to add your site to your sites list. You can add any site that you own that complies with the AdSense Programme policies.
Adding your sites protects you from malicious use of your ad code by others. The sites in your sites list are the only sites that are permitted to use your ad code. If a site displaying your ad code isn't on your list of sites, then no ads will show on that site.
To access your sites list:
- Sign in to AdSense, and click Sites.
