Performance Marketers Shift From Attribution to Incrementality
The article argues that traditional attribution is weakening as discovery compresses into higher-intent moments driven by AI and fragmented commerce touchpoints. Performance marketers are increasingly prioritizing incrementality — testing whether activity actually causes new revenue — over last-click attribution. Industry research (eMarketer and TransUnion) and practitioner quotes show incrementality rising as a top KPI for retail/commerce buyers. The piece differentiates 'commerce media' (any advertising powered by first-party transaction data across owned touchpoints) from retail media and highlights the 'Transaction Moment' (checkout/confirmation/post-purchase) as a high-signal environment for incrementality tests. Examples cited include Rokt’s partnership with incrementality platform Haus and a Tails.com case (working with Rokt) that drove a 153% uplift in conversion. The article frames the shift as pushing performance teams to evaluate channels by efficiency, provable incremental lift, and long-term customer value.
Signals a measurable industry shift from last-click attribution to incrementality and commerce-media measurement; affects how brands, retail networks and measurement vendors allocate budgets and design tests.

Brands Ignore Measurement; Incrementality Solves Attribution
Trevor Testwuide, CEO and co-founder of Measured, published a sponsored op-ed arguing that modern platform-reported attribution (last-touch and platform claims) systematically misallocates marketing budgets. The piece recommends incrementality testing—using exposed vs. matched control groups (holdout tests)—to measure true causal lift and avoid paying repeatedly for demand a brand already had. It notes that retail media networks, social commerce, AI-driven discovery, and marketplaces exacerbate attribution errors, and explains that adopting incrementality requires organizational changes (incentives, agency pushback, revised KPIs) but yields clearer budget allocation and growth-focused investment. The article was published on Modern Retail and sponsored by Measured on 2026-07-02.
TikTok Expands Off-Platform Ad Network to US
TikTok expanded its TikTok Ad Network (formerly Pangle) to US advertisers, announced at Advertising Week New York. The network spans nearly 400,000 premium third-party apps globally, allowing advertisers to extend campaigns off-platform. It aims to increase TikTok's share of ad budgets by leveraging its data and algorithms. Advertisers express cautious interest, seeking transparency, control, and proof of incremental reach, while noting competition from Google, Meta, and Amazon. Some see potential for lower CPMs and improved performance with proper guardrails. TikTok's US ad revenue was $14.12 billion in 2025, projected to reach $17.69 billion in 2026, with global ad revenue projected at $43.89 billion by end of 2026.
