CMOs accustomed to a focus on crafting polished brand messages for their own websites and traditional search are waking up to a new digital marketplace. Increasingly, buyers aren’t clicking links on search pages—they’re going to AI assistants to do work-related research, get detailed answers to personal questions, find product recommendations and even manage shopping lists. Brands can no longer rely solely on Google rankings—they need to show up in the AI-generated summaries people read, quote and act on. While a November 2025 Semrush report noted that ChatGPT is citing Reddit and Wikipedia less frequently than it has in the past, they’re still among its top three sources—a signal that “useful” content in the GenAI era often looks less like a polished campaign page and more like a living knowledge base. Companies are responding in a shift that’s been framed as a move toward generative engine optimization (GEO), where visibility increasingly depends on whether your expertise is shared in such a way that it answers real questions and can be pulled, summarized and trusted in AI-driven results.  So what new strategies should marketing leaders pursue in the face of these changes? Here, members of the Senior Executive CMO Think Tank—experts in brand storytelling, digital advertising, customer engagement and the rise of AI in marketing—share what these citation patterns suggest about the content AI models treat as credible and offer practical ways to rethink content and engagement.
