Advertising Cookies
Google AdSense uses advertising cookies. An advertising cookie is a cookie that gets placed on a user’s device when the user clicks on an ad on a partner’s website.
Google requires all websites and mobile apps that use AdSense to inform visitors and users of Google’s advertising cookie usage.
Google has a section in its AdSense Help that addresses exactly what advertising cookies are and how you, as a website or mobile app operator, can update your Privacy Policy in an appropriate way to include this information:
According to Google, if you use AdSense, your Privacy Policy should include the following information and let users know that:
- Third party vendors, including Google, use cookies to serve ads based on a user’s prior visits to your website
- Google’s use of the advertising cookie enables it and its partners to serve ads to your users based on their visit to your sites and/or other sites on the internet
- Users may opt out of the use of the advertising cookie for interest-based advertising by visiting Ad Settings. (Alternatively, you can direct users to opt out of a third-party vendor’s use of cookies for interest-based advertising by visiting aboutads.info)
Google doesn’t give specific guidelines beyond the above points because laws vary, but so long as the above points are made, your legal agreement should be adequate to satisfy Google’s requirements at least.
