Advancing transparency in media measurement

Marketing and advertising leaders are under growing pressure to justify media investment, prove impact and maintain confidence across an increasingly complex media ecosystem. Yet fragmented data, inconsistent attribution and limited cross‑channel visibility continue to erode trust in reported performance — turning measurement into a leadership challenge, not just a technical one.

Based on research conducted by The Harris Poll, Advancing transparency in media measurement, examines how these challenges are reshaping decision-making — and why transparency is increasingly essential for organizations seeking more confident, defensible media investment. 

Drawing on insights from more than 2,300 senior leaders globally, the research highlights where transparency and attribution gaps persist, and the shifts leaders report making in response. These include increased investment in measurement capabilities, a move toward more controllable environments like commerce media networks and growing openness to shared standards that can restore trust in performance data.

Inside you’ll discover:

• Why measurement uncertainty is eroding credibility and limiting budget confidence as pressure to justify spend rises
• Where transparency, attribution and cross‑channel comparability gaps persist — and how those gaps are influencing investment decisions
• How closed‑loop measurement, commerce media, privacy‑first collaboration and AI are emerging as clear paths to overcome complexity
