Steps

  1. Implement or configure a GPP-compliant CMP that generates a GPP string covering the relevant US jurisdictions
  2. Append gpp={gpp string} and gpp_sid={gpp section id} as URL parameters on ad requests sent to Google Ad Manager
  3. Confirm the GPP section strings are limited to the jurisdictions Ad Manager accepts: US National, California, Colorado, Connecticut, Florida, and Virginia
  4. Verify Ad Manager applies restricted data processing when the string signals an opt-out of sale, sharing, or targeted-advertising processing, per the specific state's rule
  5. For EEA/UK/Switzerland traffic, continue using a certified CMP's IAB Europe TCF integration instead
