SEO remains essential. But it no longer answers the whole question: in a world where users ask ChatGPT, Gemini, Claude or Perplexity directly for a recommendation, visibility is no longer limited to a position on Google. It's also measured by a brand's ability to be cited, understood and recommended by AI engines.
GEO, short for Generative Engine Optimization, doesn't replace SEO. It extends it. SEO helps a page be found. GEO helps a brand be picked up in an answer. This nuance changes the way you produce content, build authority and measure results.
1. SEO targets a position, GEO targets a mention
In SEO, the classic goal is to appear as high as possible on a results page. The logic is vertical: the higher you are, the more likely you are to be seen and clicked.
In GEO, the goal is different. The user doesn't always see a list of links. They get a synthesis. In that synthesis, your brand can be cited, ignored, poorly described or recommended. So the real question becomes: does AI include you in its answer?
A business can be properly ranked on Google, yet absent from a generative answer that cites three competitors. Conversely, a highly specialised brand can be recommended by an AI because its content is clearer, better structured or more aligned with the search intent.
2. SEO measures the click, GEO measures the citation
SEO relies on metrics like position, impressions, CTR and organic traffic. These metrics remain useful, but they're no longer enough when part of the answer is consumed without a click.
GEO adds other metrics: mention rate, share of voice, rank in the answer, sentiment associated with the brand, sources used, competitors cited alongside you. This data shows not only whether you're visible, but also how you're presented.
In SEO, a visit is often the signal of success. In GEO, a reliable citation in the answer can already influence the user's decision.
3. SEO optimises pages, GEO optimises passages
SEO works heavily on the page: title, tags, internal linking, content, intent, technical performance. GEO also works on the page, but with an added constraint: AI engines often pull fragments of content, or chunks, to compose an answer.
So good GEO content must be chunkable. Each section should be able to stand almost on its own: a clear definition, a verifiable statement, a structured list, a simple example. Long, vague blocks, overly marketing promises and paragraphs with no concrete information are harder to reuse.
The right question to ask is no longer just “is this page optimised?”, but also “can this passage be cited as-is by an AI?”.
4. SEO looks at links, GEO looks at the full footprint
Backlinks remain an important authority signal. But generative engines also reason with broader signals: brand-name consistency, unlinked mentions, customer reviews, directories, comparison pages, structured data, trade media, company listings, third-party sources and topical reputation.
A brand that only exists on its own site is harder to validate. A brand consistently present across several reliable sources is easier to understand and recommend.
So GEO pushes you to work on the whole proof ecosystem: what your site says about you, but also what other sources confirm.
5. SEO answers queries, GEO answers decisions
Many AI queries are phrased as requests for advice: “which tool to choose?”, “who do you recommend?”, “what solution for my business?”. The user isn't just looking for information. They're looking for a simplified decision.
That's why GEO values comparison content, use cases, selection criteria, proof, limitations and direct answers to objections. Content that clearly explains who a solution is suited for is more likely to be used in a recommendation.
What to do now
- Conserver les fondamentaux SEO : crawl, indexation, performance, structure, maillage et contenus utiles.
- Add citable blocks: definitions, FAQs, comparisons, criteria lists, figures and proof.
- Strengthen entities: consistent brand name, structured data, “about” pages, profiles and third-party sources.
- Measure AI answers on a panel of real prompts, not just Google positions.
The best starting point is to compare your current visibility against your competitors on generative engines. You'll quickly see where your brand is already understood, where it disappears and which sources influence the answer.
