Falling Match Rates Make Attribution an Illusion
Cimin Ahmadi Cohen, founder and CEO of Idea Peddler, argues in an AdExchanger interview that declining match rates driven by privacy regulation, changing consumer attitudes, and shifts in traffic are undermining digital attribution. Idea Peddler co-authored a white paper, “The Attribution Illusion,” with PJX Media, Share Local Media and Locality (with help from a New York Times investigative journalist) asserting that poor match rates are causing wasted programmatic spend and misleading performance metrics. Cohen says her agency has reduced pure programmatic display, is leaning into contextual and premium CTV environments, and expects brand-lift studies and marketing-mix-modeling to supplement or replace current attribution models. The interview highlights industry pressure to rethink identity, measurement, and media strategies as cookies and conventional tracking become less reliable.
Highlights systemic measurement and identity challenges (falling match rates and unreliable attribution) that can cause billions in wasted programmatic spend and push marketers to adopt contextual, CTV, and MMM approaches.

Match Rate: The Overlooked Metric Costing Ad Spend
The article argues that 'match rate' — the share of an uploaded first‑party audience a platform can recognize and target — is a critical yet undertracked metric that sits upstream of every paid-media KPI. Privacy changes (third‑party cookie deprecation, Apple ATT), identifier fragmentation, and inconsistent formatting mean platforms often match only a subset of uploaded lists; platforms then report performance only against that matched subset. Low match rates reduce acquisition precision, weaken retargeting, undermine suppression lists, and skew lookalike models. The author cites CKE Restaurants using Rokt mParticle’s Match Boost to increase match rates (up to 117% on Google and 29% on Meta) and improve ROAS without changing spend or creative. Recommended actions: measure match rates on top paid destinations and suppression lists, and consider in‑flight identifier enrichment at the CDP-to-ad-platform connection while preserving governance.
Yapily CEO Prefers Sidelines amid Open Banking Consolidation
Yapily, a UK-based open banking infrastructure startup backed by Lakestar, reported improved financials for 2025, with turnover rising from £6.7m to £16.7m and a swing from a £16.2m loss to a £355,000 profit. CEO Stefano Vaccino attributes growth to a lean operation and increased revenue from existing customers including Revolut, Intuit, Adyen, and Google. The company, profitable since 2025, last raised a $51m Series B in 2021 led by Sapphire Ventures. Amid expected consolidation in the open banking sector, Vaccino stated a preference to remain on the sidelines and focus on organic growth. He highlighted upcoming catalysts such as Commercial Variable Recurring Payments (CVRPs) and the EU's Financial Data Access (FiDA) framework, while noting recent acquisitions like Paypoint's purchase of obconnect and TrueLayer's acquisitions of in3 and Zimpler.
SPUR launches AI content tracking standard, invites OpenAI, Google to board
A coalition of media organizations including the Guardian, Financial Times, BBC, Sky, and the AP has released a new standard for tracking how AI tools use publishers' content. The Standards for Publisher Usage Rights (SPUR) initiative published its content telemetry standard on October 2, 2026. The standard creates a process to track and report when content is retrieved, grounded, cited, presented, and engaged with by AI tools, and report usage back to publishers. SPUR has invited OpenAI, Anthropic, Google, Meta, and Microsoft to join its new AI Licensing Advisory Board to help shape implementation. The board aims to ensure tracking rules work for both publishers and AI companies. SPUR is also developing agent tooling for AI companies to adopt the standard, supporting transparent reporting and licensing. Pilot programs with tech and AI companies are planned.
