I make your brand visible in AI answers.
I'm Eugen Ullrich, GEO & AI Visibility Strategist. I make brands visible and citable when buyers ask ChatGPT, Perplexity, Gemini or Claude for a recommendation. Foundation: over eight years of technical SEO, up to 20 million pages. For clients across DACH, Europe and the US.
Visibility isn't an end in itself. It should generate inquiries and revenue, and that's what I optimize every measure for. I work at the intersection of classic search and AI answer engines. More and more buying decisions start there: in ChatGPT, Perplexity and Google's AI Overviews rather than in the classic list of links.

How I work
