Advertisers' Hesitation Frustrates Open-Web ID Adoption
Publishers, sellers and media experts agree the open web needs deterministic identifiers to better measure and monetise reach. Progress toward a shared identifier ecosystem is slower than expected because most advertisers prefer to wait rather than adopt solutions now. Industry participants express frustration at this hesitancy. The article references a prior interview with Kristina Bulle from a year earlier calling for improved reach in the open web. The piece was published by HORIZONT on 2026-08-18 and authored by Klaus Janke.
Slower advertiser adoption of deterministic ID solutions hinders open-web addressability, affecting publishers' monetisation and cross-channel measurement — a meaningful operational issue for the AdTech ecosystem.

Window for Open-Web ID Push Is Shrinking
Commentary by Klaus Janke (Horizont) warns that the time to deploy deterministic identity solutions in the open web is running out. The article argues that practical adoption of deterministic identifiers such as NetID and Utiq is necessary for the open web to preserve reach and to sustain quality journalism as a pillar of democratic public life. The piece frames the issue as urgent: without widespread implementation of shared identifiers, publishers and the open web risk declining monetization and audience measurement capabilities.
Open Web: The Future of Transparent Advertising Awaits
The article argues the advertising industry must now operationalize a functioning Open Web that restores transparency, control and interoperability after a decade dominated by walled gardens. It identifies structural problems with closed platforms—limited auditability, non-comparable metrics, closed data ownership and reduced media diversity—and presents IAB Content Taxonomy and the EU Digital Markets Act (DMA) as complementary technological and regulatory foundations. Digital audio is used as a case study (noting Spotify’s withdrawal from shared measurement bodies) to illustrate measurement and ID challenges. The piece calls for deterministic, interoperable ID infrastructures (e.g., NetID, Utiq, Listener-ID), cookieless readiness (contextual methods, clean rooms) and concrete action from advertisers, publishers and agencies to diversify budgets and roll out standards.
Open Web's Path: Embrace Standards for Growth
Ahead of ADZINE CONNECT 2026, industry leaders discussed how the Open Web can remain competitive with Walled Gardens by leveraging its strengths—transparency, contextual quality and cross-publisher control—while addressing technical and measurement gaps. Speakers argued Open RTB works well for single-impression programmatic trading but does not cover many premium, private-deal and direct-booking use cases. Measurement (notably attention metrics and cross-platform frequency capping) and fragmented standards for contextual targeting, identity and creatives are cited as key obstacles. Proposed remedies included new abstraction layers around campaign goals, allowing external measurement in closed platforms, adoption of deterministic identity where applicable, and protocols such as the Ad Context Protocol (AdCP) and agentic systems to reduce complexity.
