Generative Engine Optimization: techniques to be cited as a reference source in answers from conversational AIs (ChatGPT, Perplexity, Gemini, Copilot, Claude).

Will GEO replace SEO?

No. Google still handles 8.5B searches/day. GEO complements SEO — we call it 360° visibility.

Time to see GEO results?

2 to 6 months depending on initial domain authority. AI models update their indexes more frequently than Google.

How much does a GEO strategy cost?

Full GEO setup (llms.txt, 15+ Schema.org types, monitoring): €2,500 to €8,000 one-shot. Monthly retainer: €500 to €2,000 depending on content volume.

GEO: getting cited by AI — the complete 2026 guide

2026-05-08·20 min read

GEO (Generative Engine Optimization) is the set of techniques to optimize a brand's visibility in answers generated by ChatGPT, Perplexity, Gemini, Copilot and Claude. According to OMNIRK 2026 monitoring, ~40% of searches end without a click and 60%+ of B2B buyers use a conversational AI in the discovery phase. GEO is the missing pillar of any digital visibility strategy.

Why GEO is urgent in 2026

ChatGPT hit 100M users in 2 months. Perplexity claims ~100M active users. Google AI Overviews appears on 30-40% of informational SERPs. The question isn't 'should I do GEO?' but 'how many clients have I lost because competitors are cited instead of me?'

SEO vs GEO: the complementarity

SEO targets search engines (Google, Bing) measured in positions / traffic. GEO targets generative AIs measured in citation rate and AI Share of Voice. SEO time-to-result: 3-12 months. GEO: 2-6 months. They reinforce each other — strong SEO makes GEO easier.

How AIs choose their sources

Two mechanisms: (1) training memory — LLMs memorize well-indexed sites cited on media / forums; (2) real-time retrieval (RAG) — Perplexity and ChatGPT browsing do live web search before answering. Your technical SEO has a direct impact.

AI citation factors

Domain authority (DR 50+), semantic clarity (Q/A cited 2.3× more often), factual data (numbers, dates), cross-source mentions (Wikipedia, media, Reddit, LinkedIn), content freshness, Schema.org structured data, and AI crawler access (GPTBot, PerplexityBot, ClaudeBot allowed).

The 8 GEO techniques to implement

1) llms.txt + llms-full.txt at root; 2) Server-Side Rendering (SSR); 3) Schema.org JSON-LD (FAQPage, Article, Organization, HowTo, Product); 4) Q/A structured content; 5) Cross-source presence (Wikidata, media, Reddit, LinkedIn); 6) Explicit AI crawler authorization in robots.txt; 7) Open Graph and rich metadata; 8) Monthly AI citation barometer.

The OMNIRK GEO Score

Our 100-point maturity model: AI files (llms.txt, ai-plugin.json) 20 pts, Schema.org and structured data 20 pts, SSR and crawler access 15 pts, authority and cross-source presence 20 pts, Q/A content and named entities 15 pts, monitoring and freshness 10 pts.

B2B GEO: maximum ROI

60%+ of B2B buyers use conversational AI in discovery. Highest ROI sectors: SaaS, professional services (law, consulting), health, training. If you're not cited in the Perplexity answer a CIO gets for 'best enterprise cybersecurity software', you don't exist in their evaluation process.
