Audience Decay Monitor

Detect saturated Meta audiences — rising CPA with rising frequency — before they tank your overall account performance.

Audience saturation is one of Meta's most common failure modes: your ad set burns through the responsive portion of an audience, frequency climbs, CPA creeps up, and ROAS quietly bleeds. The Audience Decay Monitor watches for the canonical pattern across your active audiences.

What you need

  • A Meta Ads connection.

  • Active audiences with at least 14 days of run history.
