Average CPM
Average CPM helps you assess your overall ad efficiency across platforms. Here’s everything you need to know: what it is, why it matters, how to calculate it, and how to optimize it!
Formula
Average CPM = (Total Spend Across Campaigns ÷ Total Impressions) × 1,000
Example. If you spend $2,000 for 400,000 impressions across multiple platforms, your Average CPM is ($2,000 ÷ 400,000) × 1,000 = $5.
What it is
Average CPM is the total cost to deliver 1,000 ad impressions across all campaigns and channels. It represents a blended view of CPM across placements and helps you benchmark efficiency.
Why it matters
Average CPM allows marketers to monitor trends over time, compare platform efficiency, and control costs at scale. It’s especially useful for media planning and budget forecasting.
How it is calculated
Add the total cost of all campaigns and divide by total impressions (in thousands).
A good value
A good Average CPM depends on your industry and ad format, but anything under $8 is often considered efficient for display and awareness campaigns.
A bad value
A rising Average CPM without improved outcomes can indicate wasted budget or market saturation.
Do
Apply these strategies to improve cost-efficiency across all your advertising.
- 01
Use real-time performance dashboards
Monitor CPM trends across campaigns to identify anomalies and shift budget efficiently.
- 02
Compare platforms side by side
Analyze CPM by channel—social, display, video—to pinpoint where you’re getting the best value.
- 03
Combine CPM with post-impression metrics
Track not just how much you pay for views, but also how those views contribute to conversions or sales.
Avoid
Don’t rely on averages alone—dig into segmented data to understand where budget inefficiencies hide.
