What is CPM?

CPM (Cost Per Mille) is the cost to deliver one thousand ad impressions. It is the standard buying and benchmarking metric for awareness and upper-funnel media.

Why is CPM Important?

  • Awareness budgeting

    Prices reach campaigns in a comparable unit.

  • Auction insight

    Rising CPMs signal competition or tighter targeting.

  • Planning

    Estimates impressions available for a given budget.

  • Placement comparison

    Compares inventory costs across networks.

  • Brand campaigns

    Fits goals where clicks are secondary to reach.

How is CPM Calculated?

Formula

CPM = (Ad spend ÷ Impressions) × 1,000

Divide ad spend by impressions, then multiply by 1,000.

Factors Affecting CPM

  1. 01

    Audience tightness

    Narrow targeting usually raises CPM.

  2. 02

    Seasonality

    Q4 and peak events inflate impression costs.

  3. 03

    Placement quality

    Premium inventory costs more per thousand.

  4. 04

    Creative engagement

    Poor engagement can worsen delivery costs on some platforms.

  5. 05

    Geography

    Competitive markets command higher CPMs.

  6. 06

    Industry demand

    Category competitors bid up auctions.
