When Google Ads operates under restricted data processing, Google will restrict how it uses certain unique identifiers and other data processed in the provision of services. For example, Google will disable adding to or updating remarketing lists using data to which restricted data processing applies. Ads with third-party ad tracking or third-party ad serving will continue to serve under certain circumstances as detailed in the Google Ads help center. Third-party click tracking will continue to operate as usual, with no changes when restricted data processing is enabled. Note that you should ensure that you’ve taken any measures with respect to such third parties as required to meet your CCPA compliance needs. Additionally, conversion tracking will continue to operate when restricted data processing is enabled.
See the Google Ads help center for more information, including with respect to conversion tracking, and information on how to enable restricted data processing.
