Last Click CPA Misleads On Meta Andromeda
- In-app last-click CPA is a poor judge of individual ad performance inside Meta Andromeda.
- Andromeda sequences creative across users so an ad's contribution may be first-touch or middle-touch, not last-click, which skews CPA signals.
Evaluate Ads By Contribution Not Last Click
- Look at ads as contributors inside a full ecosystem rather than pausing based on in-app CPA alone.
- Use first-click import or an attribution suite (Tier 11 Data Suite, Wicked Reports) to measure true contribution across channels.
Generative Recommendations Change Ad Ranking
- Andromeda's 'gem' update adds a generative recommendations layer that ranks which ads get shown after candidate selection.
- This second brain changes creative scoring and makes granular creative elements determinative for delivery.
