Facebook/Meta Ads - Comscore Breakdown

Planned
Isaac Field User

Connector name: Facebook Ads

Table name: (Custom Report Dimension) - Comscore Market breakdown

Column to add: comscore_market

API documentation link: https://developers.facebook.com/docs/graph-api/reference/adgroup/insights/

 

Additional details: Facebook/Meta is migrating away from using Nielsen DMA Markets and is going to use Comscore Markets in it's place. We need the ability to use comscore_market as a breakdown the same way we use dma_region currently.

    Hi Isaac,

    Thanks for flagging this. It's on our radar, and we're planning to add the comscore_market breakdown for our custom reports soon, then start migrating prebuilt reports. 

    Have you spoken with Meta about this? The blog post they published originally said this was scoped to automotive ads. Now those docs have been removed: https://developers.facebook.com/blog/post/2026/03/13/transitioning-from-nielsen-dma-to-comscore-markets-for-automotive-model-ads/.

    There's still nothing about this change in their API changelogs or docs. Another Fivetran customer told us their Meta account team told them they'd start limiting the usage of DMA in Ads Manager by the end of April. I haven't found that info elsewhere. 

    We're treating this as a high priority regardless because of the importance of the field, but I'm just asking Fivetran customers for any info they have, since Meta is doing a bad job communicating this change. 

    Cheers,
    Luke
