In 2026, the customer journey has gone 'silent': AI agents and zero-click searches now mediate interactions, making old click-based models and navigation tracking completely inadequate. This session outlines our proposition for end-to-end measurement that unifies signals from the pixel to offline CRM data, centralizing everything in BigQuery. We will shift the focus from vanity metrics to CLTV and pCLTV. We’ll explore why incrementality measurement protocols and Marketing Mix Modeling (MMM) are now the only tools capable of proving the real impact of marketing on company margins.
