What is dCPM—and why does it confuse so many people in digital advertising?

In this video, I break down what dCPM (dynamic CPM) actually means, how it evolved from the ad network era to modern programmatic platforms, and why it’s still widely misunderstood today.

We’ll cover:

The difference between fixed CPM and dynamic CPM

How auction-based pricing works in practice

Why platforms like The Trade Desk, Google, and Meta use different terminology

The key tradeoff: efficiency vs predictability

And most importantly… who controls pricing and who takes the risk

If you work in digital media, ad tech, or yield management, understanding dCPM is critical—not just as a pricing concept, but as a framework for how decisions are made in modern advertising systems.

Key takeaway:

dCPM isn’t a standardized industry term—it’s a concept that shifts control, risk, and pricing decisions in ways that aren’t always obvious.
