Cost Per Mille (CPM)
The cost of one thousand advertising impressions — the standard pricing unit for display, video, and awareness campaigns.
Cost Per Mille (CPM — from Latin 'per thousand') is the cost of serving one thousand advertising impressions. CPM is the standard pricing unit for display, video, CTV, and awareness-focused campaigns where reach and frequency matter more than immediate conversion. CPM rates vary dramatically by audience quality, context, and platform: LinkedIn B2B CPMs ($8-15), Facebook/Instagram CPMs ($5-12), YouTube CPMs ($2-8), programmatic display CPMs ($0.50-3), CTV CPMs ($15-40+). Higher CPMs are justified when audience quality is superior — a $15 LinkedIn CPM reaching C-suite decision-makers is often more efficient than a $3 display CPM reaching a broad, low-intent audience. Effective CPM (eCPM) normalizes across CPC and CPM buying models for cross-channel comparison.
