Formula
CPM helps compare impression-based buys. Pair it with CTR and conversion rate to estimate whether low impression cost can turn into useful revenue.
Formula
CPM = campaign cost / impressions * 1,000. Clicks = impressions * CTR. Orders = clicks * conversion rate.
Example
How to read the result
- CPM only measures cost to reach people, not whether the audience is qualified.
- CTR and conversion rate turn impression cost into business impact.
- Higher CPM can be worth it when downstream conversion quality is materially stronger.
Common mistakes
- Buying cheap impressions without checking click and conversion quality.
- Comparing CPM across channels while ignoring intent differences.
- Forgetting that frequency and audience saturation can lower marginal performance.
FAQ
What does CPM mean?
CPM means cost per thousand impressions. It is common for display ads, sponsorships, newsletters and awareness campaigns.
Is a low CPM always good?
No. Cheap impressions can still perform poorly if they do not generate qualified clicks, leads or orders.
Can CPM be compared across channels?
Yes, but compare downstream quality too. A higher CPM can be better if conversion rate or order value is much stronger.
Important limits
- Impression quality varies across placements, countries and audiences.
- Use CPM with CTR, conversion rate and revenue data before judging performance.
