Stefan Delaunay is an SEO and AI visibility strategist at eleven.run, dedicated to solving one of modern marketing’s biggest shifts: how brands stay discoverable when search engine results are generated by artificial intelligence.

With a deep background in technical SEO and organic growth strategy, Stefan bridges the gap between classic search optimization and generative search engines. He works at the intersection of Answer Engine Optimization (AEO), Generative Engine Optimization (GEO), entity-based schema, and structured data, helping brands establish the authority signals that LLMs require to quote, cite, and recommend them.

At eleven.run, Stefan focuses on data-backed approaches to brand visibility. Rather than relying on outdated keyword density models, he builds systems designed around semantic intent, knowledge graph integration, and multi-platform presence across ChatGPT, Perplexity, Gemini, and Google AI Overviews. His mission is to help companies transform organic search from a reactive channel into a resilient, future-proof acquisition engine.
