eMarketer, Partnerize warn AI discovery is outpacing marketing measurement

By AI, Created 11:36 AM UTC, June 02, 2026, /AGP/ – New research from eMarketer and Partnerize says AI-driven search and discovery are changing how consumers find brands faster than marketers can measure the impact. The study found most marketing leaders see the shift, but few can tie AI influence to revenue or partner compensation.

Why it matters: - AI-driven discovery is changing how consumers find and evaluate brands before they click. - Marketers risk losing visibility into influence, revenue attribution, and partner compensation as more buying journeys start inside AI tools. - Publishers, creators, and commerce partners may shift attention toward brands that can measure and reward AI-influenced outcomes.

What happened: - eMarketer and Partnerize released a study, From Clicks to Influence: The New Economic Model of AI-Driven Commerce, based on a survey of 100 U.S. marketing leaders. - 91% of respondents said AI-driven search and discovery are already changing how their organizations approach marketing. - Only 13% said they have a clear way to connect AI-driven visibility to partner compensation. - The report says AI-generated recommendations, summaries, and discovery experiences are reducing the role of clicks in commercial decision-making.

The details: - 60% of marketing leaders said AI-driven discovery is the hardest marketing channel to attribute accurately. - Only 8% of organizations can track AI-driven discovery’s influence on revenue and conversions end to end. - 41% of marketers rely on multiple disconnected systems as their main source of truth for measurement and reporting. - 51% plan to shift budget into content and SEO if AI-driven discovery keeps eroding traditional search traffic. - 38% plan to increase investment in performance-based partnerships tied to visibility or outcomes. - The report says nearly two-thirds of marketing leaders worry publishers and content partners may favor competitors with stronger measurement and reward systems. - Partnerize CEO Matt Gilbert said consumers are making decisions before a click occurs, and that traditional attribution models were never built to capture that influence. - EMARKETER principal analyst Max Willens said affiliate content sites and creator- and user-generated content can strongly influence AI visibility, and that understanding and rewarding that influence is becoming more important. - The report says affiliate content, publisher recommendations, creator ecosystems, and trusted third-party sources are showing up more often in large language model outputs and AI-generated search experiences. - The report describes this shift as a “machine-mediated market,” where influence happens upstream of the click. - Partnerize introduced VantagePoint, an auditable influence measurement and compensation system for AI-mediated commerce. - Partnerize also launched Lighthouse, a validation program for brands, publishers, creators, and technology partners to test compensation models for AI-driven influence. - The full report is available here. - Partnerize’s social presence is listed at LinkedIn.

Between the lines: - The study suggests attribution is becoming a business-model issue, not just a reporting problem. - Brands that cannot connect influence to economic value may lose leverage with publishers and creators as AI reshapes where attention is allocated. - The research also implies that measurement standards may be set by companies willing to build infrastructure before the market agrees on one rulebook. - Recent discussions at the EMARKETER Ad Buyers Summit between Max Willens and Partnerize Chief Product Officer Andy Crossen reinforced the idea that third-party content is increasingly shaping AI search outputs.

What’s next: - Marketers are likely to keep revisiting attribution standards, partner compensation, and budget allocation as zero-click discovery expands. - Partnerize says brands that invest now in transparent measurement and auditable influence models may help define future commercial standards. - The report points to growing pressure on brands, publishers, and creators to prove value in AI-mediated discovery environments.

The bottom line: - AI is changing how influence is created, but marketing measurement has not kept up.
