Exclude wasted placements and sites
Applying a traffic audit finding now works for single ad slots and sites, not only whole exchanges. Domains still need a list.
September 2, 2026. The nightly traffic audit (Supply Audit) can now act on its most common findings: individual ad slots (placements) and sites.
- What changed. We used to refuse placement and site findings with a message saying they needed a special list object we could not create. The exchange's own list of targeting options says otherwise: placements and sites are direct settings. Domains and app bundles still need a list, so those findings stay blocked for now.
- Why it mattered. That one wrong sentence had been blocking most of the waste the first audit could see.
- What apply does. It creates a new targeting set without the flagged supply. It never pauses a campaign, never changes a budget, and never touches live delivery on its own. Point the next campaign at the new set (for example by copying the campaign) and the flagged supply stops serving.
Under the hood, a finding's stored key combines the exchange and the slot; only the part after the separator goes to the exchange, because the full key matches nothing. Details: placement vs site vs domain.
