TL;DR

SEO optimises your visibility in Google's results. GEO optimises your citability in the answers of AI engines (ChatGPT, Claude, Perplexity, Gemini). They're complementary, but they run on completely different mechanisms. NEXUS GEO is the first French agency to master both in parallel.

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.

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.

NEXUS GEO insight

Content well-structured for SEO (clear H1/H2 hierarchy, semantic markup, authority signals) is often already a strong starting point for GEO. The difference: GEO additionally requires extractible blocks, structured FAQs, a coherent Knowledge Graph and an llms.txt file. That's the extra engineering NEXUS GEO brings.

How NEXUS GEO masters both disciplines

NEXUS GEO was born from the conviction that GEO can't be improvised by adding a few pages to an existing site. Our three-step methodology — AI Audit, Content Engineering, AI Pre-selection — integrates an analysis of the existing SEO to identify synergy levers. Result: our clients don't sacrifice their SEO to win on GEO. They win on both fronts.

  1. AI Audit (47 criteria): analysis of existing SEO + GEO scoring out of 100 + competitor benchmark on AI engines.
  2. Editorial engineering: production of AI-optimised content without degrading on-page SEO.
  3. AI Pre-selection: technical rollout (schema.org, llms.txt, Knowledge Graph) and monthly citation tracking.
