The Shift to Output-Based Pricing — WPP Tests New Model with JLR

The advertising industry is undergoing a fundamental shift in its economic model. Major agencies, including WPP, are moving away from traditional "billable hours" toward output-based pricing models that prioritise measurable sales and brand performance.

Core Industry Shift: From Hours to Outcomes

• The New Model: Agencies are increasingly aligning compensation with business results rather than labour hours. This treats advertising as COGS (Cost of Goods Sold) rather than OPEX (Operating Expense).
• Key Drivers: Big Tech influence (marketers accustomed to paying only for results) and a performance focus moving value toward outcomes rather than delivery volume.
• The Challenge: Publishers must evolve from selling raw impressions to providing measurable value, requiring investment in first-party data, audience intelligence, and content "stickiness."

The Problem with CPM

Ian Whittaker argues CPM is damaging because:

1. Efficiency Bias: Forces prioritisation of cheapest inventory over most effective.
2. Commoditisation: Strips away differentiation, making all inventory appear interchangeable.
3. Cost vs. Investment: Reinforces advertising as a cost rather than capital allocation toward long-term growth.

"CPM suggests a simple equation: audience × price = revenue. But advertising does not work like that... The result is an industry optimised for cost... and not for outcomes." — Ian Whittaker

Key Insights

• Transparency vs. Opacity: When measurement is difficult, complexity is often used as a business model, leading to a breakdown in trust.
• Scientific Testing: Real testing requires a hypothesis, a control group, and isolation of a single variable. Multiple variables equal noise.
• Signal Quality: As platforms automate optimisation, the primary lever for brands is signal quality. Robust data prevents platforms from "guessing" and wasting budget.

Actionable Takeaways

• For Advertisers: Shift focus from "lowest CPM" to "highest return on capital."
• For Publishers: Build commercial offerings aligned with result-oriented advertising. Prove your specific value.
• For Campaign Managers: Test one variable at a time. Prioritise LTV over short-term metrics. Audit tracking events.

Notable Perspectives

• Attention as Currency: "Delivery" is a commodity; "Attention" is the new currency.
• The Hybrid Future: A hybrid model will likely emerge as measuring each channel's contribution remains complex and costly.
