What is CPM?

Metrics

In plain English: The rent you pay for attention: cost per 1,000 ad views. A $30 CPM means $30 for a thousand people to see your ad.

Cost Per Mille, what you pay Meta to show your ad to 1,000 people. Driven by niche, audience size, creative quality score, time of year (CPMs spike 40–100% during Q4/Black Friday), and advertiser competition for the same audience.

Why it matters: CPM is the foundational cost of all your other metrics. High CPM means higher CPC, higher CPA, and a thinner margin. Your break-even math changes completely between a $15 CPM and a $60 CPM niche.

Celebrating low CPM without checking conversion rate. A $9 CPM reaching the wrong audience produces a $200 CPA. A $45 CPM reaching the right buyer intent produces a $30 CPA. CPM without CVR context is meaningless.
