GEO (Generative Engine Optimization)
GEO (Generative Engine Optimization) is the practice of optimising content to be cited as a source in AI-generated answers — for example by ChatGPT or Perplexity. Statistics, sources and expert quotes increase visibility in AI answers by up to 40% (ACM KDD 2024).
GEO starts where classic SEO ends: it is not about a position in a list of links, but about appearing in the ONE answer an AI gives its user. The foundational study by Aggarwal et al. (Princeton/Georgia Tech, ACM KDD 2024) was the first to measure which text characteristics increase the probability of being cited by AI search engines — the three most effective levers: concrete statistics instead of qualitative claims, documented sources and verbatim expert quotes. Keyword repetition, the old SEO reflex, showed no effect.
For businesses in South Tyrol and the DACH region, GEO is especially relevant because customers are ahead of the local economy: in Germany, Austria and Switzerland, 32–47% of people aged 16 to 74 already used generative AI in 2025 (Eurostat), but only 8% of Italian SMEs have launched an AI project (Politecnico di Milano, 2025). Whoever writes citably now — self-contained paragraphs that answer a question completely and verifiably — claims a spot that is still largely free.
GEO does not replace classic SEO: 97% of Google AI overviews cite at least one page from the top 20 classic results, even though many cited pages rank lower. SEO remains the ticket in; GEO is the extension.
What a website needs for GEO: AI discoverability (GEO).

Frequently asked questions.
Has classic SEO become obsolete with AI search?
No. Google AI overviews mostly cite pages that already rank well classically. SEO remains the ticket in — AI optimisation (GEO) is the extension with citable answers, structure and visible authority.
Do I absolutely need an llms.txt?
It is not a Google ranking signal (Google says so itself) — but it takes minutes to create and is useful as orientation for AI agents. A cheap addition, not a miracle cure.
How widespread it really is, we measure ourselves: as of October 2026, 14.1% of the domains probed serve an llms.txt. The measurement is open in the ai-discovery radar.
What does GEO get me — why should my website be cited by AI?
When more and more people get their answers straight from ChatGPT, Perplexity or Google's AI, whether you get found is no longer decided by your Google ranking alone — but by whether the AI names you as a source. That is where GEO (Generative Engine Optimization) comes in: it prepares your content so AI systems can read it correctly, understand it and cite it in their answers. The benefit is concrete: you get a chance of being recommended when a potential customer asks the AI for a provider like you — with clear, independently readable statements, structured data and machine-readable formats. If you're not visible here, you simply don't exist for this growing group of searchers.
Is AI visibility worth it for a local business in South Tyrol?
Right now more than ever: only 8% of Italian SMEs use AI (Eurostat/Politecnico di Milano) — so many local competitors don't have the topic on their radar yet, while 60–65% of the DACH population already actively searches via AI. This window closes a little with every season.
