Understanding eCPM

Learn the fundamentals of Effective Cost Per Mille (eCPM) and optimize your ad revenue strategy.

What is Effective CPM (eCPM)?

Effective Cost Per Mille (eCPM) is a metric that measures the revenue generated per thousand ad impressions. It helps publishers understand and optimize their ad monetization strategy across different formats and placements.

Why eCPM Matters:

  • Measures ad revenue efficiency
  • Compares ad performance
  • Guides inventory optimization
  • Helps maximize revenue
How to Calculate eCPM
(Total Revenue ÷ Total Impressions) × 1,000

The eCPM formula shows how much revenue you earn per thousand impressions. An eCPM of $2 means you earn $2 for every thousand ad impressions.

Example:

($100 ÷ 100,000 impressions) × 1,000 = $1.00 eCPM

Advanced eCPM Calculations

Beyond the basic eCPM formula, these advanced calculations provide deeper insights into your ad monetization:

(Viewable Revenue ÷ Viewable Impressions) × 1,000

Viewable eCPM considers only impressions that meet viewability standards.

Example:

($100 ÷ 80,000 viewable imps) × 1,000 = $1.25 vCPM
(Total Revenue ÷ Unique Users) × 1,000

User eCPM shows revenue per thousand unique users rather than impressions.

Example:

($500 ÷ 20,000 users) × 1,000 = $25 user eCPM
eCPM × Fill Rate × (1 - Invalid Traffic %)

True eCPM accounts for fill rate and invalid traffic to show actual earning potential.

Example:

$2.00 × 0.8 × 0.95 = $1.52 true eCPM

When to Use Advanced Calculations:

  • Viewable eCPM: For viewability optimization
  • User eCPM: For audience monetization
  • True eCPM: For accurate forecasting
