Marketers Can't Optimize Away Trust Problem
Doug Zarkin argues that modern marketing has over-prioritized measurable performance metrics—clicks, conversions and cost-per-acquisition—at the expense of earning customer trust. Drawing on the Edelman Trust Barometer and his own brand work, Zarkin says personalization has often become surveillance-like and transactional, failing to build long-term relationships. He uses examples including a local children's store's personal follow-up call and a Pearle Vision repositioning that emphasized treating people as 'patients, not customers' to show that human behavior and caregiving interactions build trust more reliably than dashboards. The piece warns that commoditized creative, weakening targeting, and AI-driven sameness make trust the remaining durable advantage: it lowers acquisition costs, increases repeat business and cannot be easily copied by competitors.
Industry-relevant commentary highlighting erosion of consumer trust and implications for performance marketing and personalization strategies; useful signal for brands and MarTech teams but not a platform policy or technical release.

Trust Is the New Brand Moat After AI
This guide argues that decades-long marketing advantages bought with money — visibility, first-to-market, premium design, and product quality — have been undermined by generative AI, which lets competitors mimic those signals. As a result, prospective customers increasingly default to skepticism and ask whether a brand is trustworthy. The author, who says they scaled trust at cloud security firm Wiz (as early Director of Growth) and via their MarketingIdeas newsletter, presents 13 ranked plays to build brand trust quickly without large budgets. The article frames trust as a durable moat that AI cannot easily cross and promises actionable steps that, when implemented, will improve conversion and inbound interest. Published on 2026-05-21.
Marketers Lose Trust in Measurement Amid Conflicting Signals
Industry figures Zach Epstein (founder of Haus) and Jon Humphrey (GM of Rokt Ads) tell The Drum that marketing measurement is failing because multiple platforms send overlapping data and claim credit for the same conversions. They argue that more data has produced conflicting signals, outdated budget inputs, and attribution that often reflects correlation rather than causation. The pair promote focusing on higher-quality, intent-confirmed environments (the 'Transaction Moment'), continuous incrementality testing and counterfactuals, and independent, causal data as prerequisites for trustworthy AI-driven marketing decisions. Haus claims its platform provides real-time signatures of incremental events to reduce insight-to-action lag.
How Brands Can Build Customer Trust Amid AI
The Drum polled its membership for industry perspectives on the role of trust in modern marketing as AI agents, privacy regulation and first-party data strategies reshape customer relationships. Multiple marketing leaders argue trust cannot be manufactured by campaigns; it must be earned through product quality, consistent customer experience, aligned incentives, transparency, human fallback from automated systems, and credible third-party validation. Contributors cite examples of trusted brands (Beauty Pie, REI, Notion, Monzo, Octopus Energy) and highlight tactics such as customer stories, digital PR and localised messaging. Several speakers warn that handing customer service wholly to AI without easy human escalation erodes trust, while agentic search and AI assistants shift where and how trust is formed.
