What happened
Zen Media launched GEO GPT™, an AI visibility diagnostic tool, to measure brand presence within generative AI responses. The system operates in three phases: building a brand knowledge base from a URL, generating a 100-prompt test set excluding brand names, and executing these prompts against Claude (Anthropic) and GPT-5 (OpenAI). Results, including Overall Visibility and Market Position, are delivered to a private dashboard, quantifying how often and where a brand is recommended by AI models. Zen Media CEO Duran Inci stated AI is already shortlisting brands, making this measurement critical.
Why it matters
Brands can now quantify their recommendation presence within frontier AI models, a previously untrackable metric. For marketing leadership and brand strategists, this tool provides a baseline for Generative Engine Optimisation (GEO), which strengthens content and authority signals for AI platforms. The diagnostic measures specific metrics like Market Position and LLM-by-LLM Comparison, addressing the constraint that AI answers do not generate traditional web analytics. Procurement teams integrate this new visibility metric into existing brand performance frameworks.
