How it works & examples

What is cost per thousand impressions (CPM)?

CPM measures the advertising cost of delivering 1,000 impressions. It is useful for comparing the cost of exposure across campaigns.

How to use this tool

CPM = amount spent ÷ impressions × 1,000. Use a positive impression count and spending from the same reporting window.

Example

$600 spent on 100,000 impressions gives a CPM of $6.

Understanding your result

An impression is a display, not a unique person, click, or sale. The same person can generate many impressions. Compare placement quality, viewability, audience, and campaign outcomes before judging a CPM.
