Meta to Transition to Comscore Markets for Automotive Model Advertising
Starting June 22, 2026, Facebook will replace Nielsen's DMA with Comscore Markets® for automotive ads. Campaigns using Nielsen’s DMA will pause until updated. From March 23, 2026, advertisers can update vehicle offer feeds with Comscore Market IDs using a provided mapping table. Notifications begin April 20, and all Nielsen DMA targeting ends June 22. Updates via Catalog Manager or API are required to resume campaigns.
