The Interactive Advertising Bureau has released its draft Cross-Channel Measurement Decision Guide for public review. The initiative seeks to standardize how marketers approach incrementality testing and attribution to improve campaign rigour.
Why it matters
The guide aims to address widespread industry frustration, as 60-75% of marketers report that current advanced measurement tools fall short on trust and efficiency. By standardizing evidence interpretation, the bureau hopes to help brands better manage conflicting data across marketing channels.
The Interactive Advertising Bureau currently maintains a membership of more than 700 entities, according to its official records. Recent data from the 2026 State of Data report indicates that 60-75% of marketers feel advanced measurement tools lack sufficient rigour and reliability.

Market Landscape
The draft guide arrives as part of the broader Project Eidos initiative, which the Interactive Advertising Bureau announced on February 2, 2026. This effort follows an industry-wide push to modernize data standards and improve the reliability of attribution methods.
Operators managing multi-channel budgets should monitor the finalization of this guide to evaluate if it offers a clearer standard for incrementality testing. Businesses struggling with fragmented performance data can review the public draft to see if the proposed decision frameworks align with their current internal reporting metrics.
The takeaway
The move signals a growing industry effort to reconcile the conflicting results that often plague cross-channel attribution. Marketing managers should prioritize reviewing the draft before the comment period ends on November 4, 2026, to ensure the proposed standards accommodate their specific operational needs.
