SEO and GEO: what are the differences for a business?
SEO and GEO pursue the same visibility goal, but they act at different points in the search journey and rely on different signals.
The short answer
When a prospect asks Google a question, they may still browse a list of links. But they can now also receive a summary, comparison or recommendation generated by AI. This development does not make SEO obsolete. It adds a second challenge: becoming a source these systems can understand and use.
SEO organises discovery
Search engine optimisation makes a page accessible, understandable and relevant to a query. It covers areas including:
- whether search engines can crawl and index the website;
- the match between a page and the user’s intent;
- the quality and originality of the content;
- internal and external links;
- performance, usability and technical stability.
A good SEO page gives someone a clear reason to click and then answers their need. That foundation remains essential, including when search results contain a generated answer.
GEO focuses on whether information can be reused
Generative Engine Optimisation looks at how a brand, service or area of expertise appears in answers produced by ChatGPT, Perplexity, Gemini or Copilot.
The most useful difference is editorial rather than technical. Content designed for generative search should make precise, contextualised and verifiable claims easy to extract. It should also identify the entity speaking: who the company is, what it does, who it serves and what evidence supports its position.
Indexing makes content available. Being clear, reliable and corroborated increases its chances of being used as a source.
The two approaches are complementary
| Question | SEO | GEO |
|---|---|---|
| Desired result | A ranking and a click | A mention, citation or recommendation |
| Main unit | The page and query | The information, entity and context |
| Useful evidence | Expertise, links and editorial quality | Precise facts, sources, consistency and external corroboration |
| Measurement | Impressions, rankings, clicks and conversions | Presence, sentiment, citations and answer context |
Generative engines often use search systems to retrieve recent sources. A page that is inaccessible, slow or isolated from the rest of the website therefore starts at a disadvantage. Conversely, technically perfect but vague or interchangeable content offers little material worth citing.
What changes in the writing
A useful strategy does not publish a separate page for every possible wording of a question. It creates a resource that covers the subject clearly and thoroughly.
In practice:
- state the main answer before the conclusion;
- divide the reasoning into precise questions;
- distinguish facts, assumptions and opinions;
- cite primary sources behind figures and claims;
- contribute what the company genuinely knows: a method, field experience or original data;
- keep important information current.
Google similarly recommends useful, reliable, people-first content for its AI-powered search features.
Where to begin
For a company, the best starting point is not a high volume of articles. Select the questions that genuinely precede a commercial decision: selection criteria, risks, costs, timelines, alternatives and conditions for success.
Each answer should then connect to a relevant service page and to other material within the same topic. This structure creates continuity between discovery, understanding and contact.
The objective is not to replace SEO with GEO. It is to build a body of knowledge that search engines can discover, people can use and generative systems can cite without ambiguity.
