Site authorization is an optional feature that allows you to identify only specific sites that are permitted to use your Google ad code. If you're particularly concerned about malicious use of your ad code by others, you may wish to use this feature as a precaution.
Authorizing your sites
* Sign in to your account.
* Visit the Home tab, then Account settings in the left hand panel.
* In the "Access & authorization" section, next to "Sites authorized to show ads," click edit.
* Check the box marked Only allow certain sites to display ads for my account.
* Enter the URL of the sites that you want to authorize, then click Save
Your changes should take effect within 48 hours.
What happens to sites I don't authorize?
If a URL displaying your AdSense ad code is not on your list of authorized sites, ads will still show on that URL, and impressions and clicks will be recorded. However, advertisers will not be charged, and you will not receive any earnings for that site.
Please note our systems might attribute a few impressions to sites that you do not control and that do not directly have your ad code on them.
