What it is
Cost per mille prices one thousand impressions—common in display, online video, and parts of programmatic buying.
Why it matters for business
When KPIs are awareness, additional journey touches, or planned reach, CPM is a simple cross-publisher yardstick.
How to apply it
Read CPM next to viewability and placement quality. For performance outcomes, translate expected clicks with CTR assumptions. Manage frequency caps.
