In context
Your campaign spent $600 and delivered 25,000 impressions: CPM = $24. If a competitor with better creatives hit $16 CPM for the same audience, they're paying 33% less to reach the same people — that's the compounding advantage of high-quality, PDA-framed ads.
Why it matters
- CPM directly affects how many conversions you can afford at a given CPA.
- High CTR (>2%) and high hook rate (>35%) reduce CPM via algorithm rewards.
- CPM is NOT a goal metric — low CPM + zero conversions = wasted spend.

Frequently asked questions
Why does my CPM suddenly jump?
Usually auction pressure (competitor bidding up the same audience) or creative fatigue (Meta penalizes low CTR).
Is $50 CPM too high?
Depends on conversion value. For $300 AOV fashion, $50 CPM can work. For $20 AOV ecom, it's usually too expensive.
Does Advantage+ reduce CPM?
Often yes — it pools audiences and placements, letting Meta find cheaper inventory. But it also concentrates spend on volume placements.
