<b>Test in ABO, scale in CBO. Here's the clean handoff.</b>

ABO (you control spend per ad set) = great for fair testing. CBO (Meta allocates) = great for scaling winners. The mistake is scaling in the same structure you tested in.

The handoff:

— Test 4-5 ad sets in ABO at equal budgets, find your 1-2 winners by CPA
— Build a fresh CBO, drop ONLY the proven winners in
— Start the CBO at the COMBINED budget the winners earned, not higher
— Let it run 48-72h before any vertical push

Clean separation = clean data. No mixing dead tests into your scaler.

Try the handoff on your next winning test.
