This study analyzed over 16 billion programmatic advertising impressions purchased by 7 major advertisers through 5 demand-side platforms. The study found that:
1) Across the full supply chain, 58 cents of each advertising dollar went to media inventory and 42 cents went to fees and costs of the programmatic supply chain.
2) Looking just at demand-side costs, 72 cents of each dollar went to media inventory and 28 cents went to demand-side fees and costs.
3) Programmatic fees can add 45% to the cost of display inventory and 35% to the cost of video inventory on average for advertisers.
The study provides recommendations to help advertisers gain more control and transparency over their program
