Definitions: SEO and GEO in plain English
SEO (Search Engine Optimization) is about optimising a website to show up in search engine results — primarily Google. The goal: generate clicks from queries typed by users.
GEO (Generative Engine Optimization) is a discipline born in 2024 that NEXUS GEO pioneered in France. It's about optimising a brand's presence inside the synthetic answers generated by AI engines — no clickable link, no SERP. The AI names your brand, explains your positioning, or recommends you directly inside its response.
Comparison table: GEO vs SEO
| Dimension | SEO | GEO |
|---|---|---|
| Target channel | Search engines (Google, Bing) | Generative AIs (ChatGPT, Claude, Perplexity, Gemini) |
| Result format | List of clickable links | Synthetic text answer with citations |
| Primary goal | Drive traffic to the site | Be named / recommended inside the AI's answer |
| Optimisation signals | Backlinks, keywords, Core Web Vitals | E-E-A-T, schema.org, llms.txt, Knowledge Graph, editorial citability |
| Success metrics | Position, traffic, clicks | AI citation rate, recommendation frequency, position inside the answer |
| Time to results | 3 to 12 months | 45 to 90 days for the first measurable wins |
| Required skills | Web tech, link building, content | Editorial engineering, Knowledge Graph, AI semantics, advanced schema.org |
Why GEO and SEO coexist (and should)
In 2026, Google still drives 55 to 70% of global search traffic depending on sector. Dropping SEO would be a mistake. But ignoring GEO means neglecting the fastest-growing channel: AI traffic grew +527% year-over-year (source: Similarweb 2024-2025), and a visitor coming from an AI converts 4.4× better than a Google visitor (source: Profound 2025).
The right strategy in 2026 is hybrid. That's precisely what NEXUS GEO delivers: 100% GEO expertise, built on a careful read of the existing SEO. Our audits integrate both dimensions to avoid conflicts and maximise synergies.
How NEXUS GEO masters both disciplines
