Identity Resolution

The identity resolution space received indirect but meaningful pressure this week from two directions. First, the GEO and zero-click search research from Digiday highlighted how AI-generated search results are eroding the click-based signals that many identity graphs rely on for behavioral enrichment — a structural challenge that identity vendors will need to address as AI search becomes the norm rather than the exception. Second, the EU Digital Markets Act enforcement analysis from Politico Pro Tech, now six months into meaningful enforcement, examined what has actually changed for AdTech — with identity and data-sharing practices between platforms among the most directly affected areas.

The addition of Verisk Marketing Solutions to the ATDb database this week also reflects the continued expansion of the identity resolution vendor landscape, as data and analytics firms with roots outside traditional AdTech increasingly bring identity capabilities to market. The convergence of regulatory pressure in Europe and signal loss from AI search is creating a genuinely difficult environment for identity resolution providers to navigate simultaneously.
