RAG (Retrieval-Augmented Generation)
RAG (Retrieval-Augmented Generation) is the technique AI answer engines work with: the language model combines its base knowledge with individual text passages retrieved live from the web before it answers. That's why the individual passage counts for visibility, not the whole page.
RAG (Retrieval-Augmented Generation) describes how modern AI assistants like ChatGPT, Perplexity or Gemini arrive at their answers. Instead of relying only on their trained knowledge, at the moment of the question they retrieve fitting text passages from an index and build the answer from them — with a source reference. For a business this means: not the whole website is evaluated, but whether individual, self-contained passages answer a concrete question cleanly and machine-readably. Clear structure and self-contained statements decide whether your content gets cited in AI answers.

Frequently asked questions.
How does an AI read my website — and what does that mean for my content?
An AI doesn't read your website top to bottom; it breaks it into individual text passages and, at the moment of the question, retrieves only the fitting ones (Retrieval-Augmented Generation, RAG). What matters is therefore not the whole page, but whether individual passages answer a concrete question on their own and machine-readably. Content loaded only via script or buried in long prose often doesn't reach the AI.
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 exactly what GEO (Generative Engine Optimization) does: it prepares your content so AI systems read it correctly, understand it and cite it in their answers. The benefit is concrete: you get 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.
