What the research supports

The decision risk is not knowing what to scale.

A flat “wasted budget” percentage suggests more certainty than the evidence provides. The defensible problem is fragmented measurement and weak links between investment and business outcomes.

32%

Only 32% of marketers globally said they measure media spending holistically across both digital and traditional channels.

This documents a measurement gap. It does not mean 68% of marketing spend is wasted.

Online survey of 1,400 global marketers at manager level or above. Every respondent managed at least $1M in annual marketing budget; two-thirds managed more than $10M.

52%

Only 52% of CMOs and other senior marketing leaders said they successfully proved marketing’s value and received credit for helping meet enterprise objectives.

The leadership problem is credibility: connect investment to outcomes that finance, sales, and the executive team recognize.

Survey of 378 senior marketing leaders conducted in April and May 2024.

What the research does not justify

No universal loss benchmark

The paper does not estimate an average annual loss. Exposure should be calculated from the company’s own spend, revenue, effect size, and decision window.

Short term ≠ long term

This supports sizing and monitoring each test on its own conditions—not guaranteeing a universal 60–90-day revenue result.
