Case Study: Dentsu achieves expanded audience reach and measurable campaign outcomes with Quantcast

Dentsu diversifies ad spend to increase audience reach

Dentsu, the world’s largest agency brand and the fifth largest agency network, needed to diversify ad spend beyond walled gardens to expand audience reach and gain deeper audience insights. The agency’s challenge was to identify relevant, responsive audiences across channels so campaigns wouldn’t be limited to a single set of data.

Dentsu built a first‑party data strategy that combined online and offline signals and partnered with Quantcast, using its data and AI to identify predictive audiences likely to take action. Across campaigns and client categories they uncovered qualified, high‑intent audiences, drove measurable business outcomes, and generated insights that improved future audience, creative, and reach planning.
