What is the most likely consequence of failing to update your AdSense privacy policy when required?

The most likely consequence of failing to update your AdSense privacy policy when required is ad serving being disabled or limited on your website. AdSense requires publishers to have a clear and comprehensive privacy policy that informs users about how their data is collected, used, and shared, especially regarding personalized advertising. This is to comply with privacy regulations like GDPR and CCPA. If a publisher fails to update their privacy policy to reflect changes in data collection practices or to meet the requirements of these regulations, Google may restrict or stop serving ads on their website until the policy is updated and compliant. This can result in a significant loss of AdSense revenue. Repeated failures to comply with privacy policy requirements can ultimately lead to account suspension or termination. The privacy policy must be easily accessible to users and accurately describe how AdSense and other third-party vendors use cookies and collect data for ad personalization.
