Advantage+ placements vs manual placement: auto wins, with one exception

Advantage+ placements vs manual placement: auto wins, with one exception
Across 48 accounts, 90d:
— Advantage+ placements (all surfaces): 16% lower CPM — Meta arbitrages cheap inventory
— Feed-only manual: higher CPM but 20% higher CVR — Audience Network and some Reels traffic converts poorly for considered buys
Net: auto-placements win on cheap eCom, manual feed-only wins on high-AOV where junk placement clicks waste spend.
Read: let placements run auto by default; force feed-only when your AOV is high enough that placement quality beats CPM savings.
