CPM — cost per thousand impressions — is what the ad auction charges you to be seen. What counts as "good" swings widely by platform and audience, and the biggest lever you control is the one most people ignore: the creative itself.
CPM = (spend ÷ impressions) × 1,000. Spend $50 to reach 5,000 people and your CPM is $10. Because impressions are sold by auction, CPM is really a measure of demand for the eyeballs you're bidding on — the narrower and more contested the audience, the more each thousand costs.
Broad ballparks for prospecting audiences in stable months. Narrow targeting, competitive niches, and Q4 push these higher.
| Platform | Typical CPM |
|---|---|
| $8–$15 | |
| $8–$14 | |
| TikTok | $6–$12 |
| Google Display | $3–$8 |
| YouTube | $9–$15 |
| $25–$40 |
Audience competition, narrow targeting, small retargeting pools, seasonal demand (Q4 CPMs can double), and low ad relevance all raise your cost per thousand. The last one is the lever you own: platforms discount impressions for creative that earns engagement, so a stronger ad literally buys you cheaper reach.
A low CPM on an ad nobody clicks is worthless. Read CPM alongside CTR, CPA, and ROAS: cheap reach that converts is the goal; cheap reach that doesn't is just a cheaper way to waste budget. Creative that stops the scroll tends to improve all four at once.
You can't out-target a boring ad, but you can pick the more engaging one before spending. Predicting how well a creative holds attention — its hook strength and full attention curve — lets you launch the version the auction will reward with cheaper impressions. See ad pre-testing.

Score Your AdIt varies by platform: roughly $6–$12 on TikTok, $8–$15 on Facebook and Instagram, and $25–$40 on LinkedIn where audiences are pricier. A 'good' CPM is one low enough that your downstream CTR and conversion rate still leave you profitable — the number alone means little without those.
CPM = (total spend ÷ impressions) × 1,000. Spending $50 to reach 5,000 people is a $10 CPM. CPM is set by an auction, so it rises with audience competition, narrow targeting, and seasonal demand like Q4.
Yes. Platforms reward engaging creative with cheaper impressions — a high-relevance, high-engagement ad often wins the auction at a lower CPM than a dull one targeting the same people. Improving the hook can lower CPM and raise CTR at the same time, which is why creative is the cheapest lever you have.
