Generative Engine Optimization (GEO)
Definition and How AI Answer Engines Select Citations
Generative Engine Optimization (GEO) (also known as AI SEO or LLM Optimization) is the engineering and editorial practice of structuring web pages with 40 to 50 word lead definitions, connected Schema.org JSON-LD entity graphs, and machine-readable llms.txt Markdown feeds so AI answer engines (ChatGPT Search, Perplexity, Google AI Overviews, and Claude) accurately retrieve and cite your brand.
We bake GEO architecture into every €4,500 to €9,000 corporate website and SEO service engagement. Read our HubSpot Content Hub vs Next.js B2B comparison.
Core Technical Pillars: SSR, Schema @graph, and llms.txt
Because LLM retrieval crawlers (GPTBot, OAI-SearchBot, PerplexityBot, ClaudeBot) do not execute client-side JavaScript bundles, pages must use static site generation or server-side rendering, paired with explicit schema markup and verifiable 2026 EUR data tables. Scale cross-border entity parity with our multilingual B2B SEO and hreflang Next.js guide. Discover how Markdown mirrors and /llms.txt work in our LLM seeding and llms.txt B2B AI visibility guide. Structure 40-word lead definitions and benchmark tables using Answer Engine Optimization (AEO).
