An opinion piece on Advantage+ Audience Expansion drawn from 80+ accounts: the three situations where leaving the toggle on works brilliantly, the four where it tanks your pipeline, and the 10% / 30% cost-of-wrong-conversion rule I use to decide.
A working Claude Computer Use agent that opens your Meta Ads Manager, reviews every ad against a 2-axis rubric (policy + brand consistency), and drops a CSV of red/yellow flags in 12 minutes — the system prompt, the build, and where the false-negative floor sits.
The actual Make.com scenario I have run every Monday for 11 months across 6 competitor accounts — pulls Meta Ad Library, sends creatives to Gemini 2.5 Flash, classifies hook style / format / offer type, writes structured rows into Airtable. Module-by-module, the exact Gemini prompt, the $0.012-per-run cost, and the three things that broke in month one.
A practical 6-step workflow for producing a full Google Performance Max asset group — 20 images, 15 copy slots, logos — in under an hour, using Claude for briefs and copy and Midjourney for visuals. Includes actual prompt templates, Midjourney batching tricks, and the three things that break first.
