Once your sites are verified and site authorization is turned on, ads will still show on the unverified site(s), and impressions and clicks will be recorded. However, advertisers will not be charged, and you won't receive any earnings for that site. Any policy violations that occur on these sites also won’t count against you.
The URLs will still show up in your list of sites so you are aware of who else is using your ad code. The sites may also still show in your performance report in order to keep a definitive record of activity. If you are seeing the sites in your reports but don’t want to, consider setting your report type to “Verified Sites” to ensure you are only seeing data related to your verified sites.
