When an advertiser adds one of their users to the advertiser’s Customer Match list, what happens to that user data?
- User data is shared with multiple publishers and platforms.
- The user’s data is made publicly available to all marketers.
- User data is added to additional Google products automatically.
- The user’s data is kept confidential and secure.
Explanation:
When an advertiser adds a user to the Customer Match list, Google ensures the data is kept confidential and secure by using hashing. This process converts the user information into codes that cannot be decrypted, ensuring privacy and compliance with strict standards. Google only uses the data to create Customer Match audiences and does not build or enhance customer profiles with this information.
