What Is Markup in Advertising? The Fee Layer Behind the Principal Media Debate

· 35m ago · Originally reported by PPC Land

Markup is the amount an agency, trading desk or reseller adds on top of the cost of media or services it buys on a client's behalf. When these add-ons are not disclosed, they fuel the ongoing principal media controversy, where agencies re-sell inventory to advertisers as principals.

Why it matters

Understanding markup helps advertisers see where their budgets actually go and why undisclosed agency fees have become a major trust issue in media buying.

Explain it like I’m new here

It's like a reseller buying concert tickets at one price and charging you more without telling you how much extra they kept.
