My keynote Mastering Digital Experience Across Platforms explores how search is transforming into a multi-platform, AI-driven experience. As traffic declines across classic SEO channels, brands must adapt to new discovery behaviors, emerging AI interfaces, and agentic search capabilities. The talk covers the shift from rankings to relevance, the rise of LLM memory and personalization, and why earning visibility now means being part of both human and machine recall. Supported by data, case studies, and the latest announcements from Google I/O, it provides a strategic framework for the next era of digital discovery.
