Key takeaways
- GEO is the practice of making your brand visible and citable in AI-generated answers.
- It builds on SEO fundamentals rather than replacing them.
- Clear answers, consistent facts and third-party mentions matter most.
From ten blue links to one answer
When someone asks ChatGPT, Perplexity, Gemini or Google's AI Overviews a question, they receive a written answer, often with a few cited sources or named recommendations. They may never see a traditional results page. If your business is not in that answer, you are invisible at the moment of decision.
Generative engine optimisation (GEO) is the work of increasing the chance that AI tools mention, recommend and cite your business for relevant questions.
How AI tools choose what to say
Each tool works differently, but most combine a language model's general knowledge with live retrieval from the web. Retrieval often relies on search indexes, which is why strong SEO remains the foundation. The model then selects passages that answer the question clearly and appear trustworthy.
- Retrieval: can the tool find your page for the question being asked?
- Extraction: does your page contain a clear, self-contained answer it can use?
- Trust: do other sources confirm what you say about yourself?
GEO vs SEO
SEO aims for a ranking position; GEO aims for a mention or citation. The tactics overlap heavily—technical health, relevant content and authority—but GEO puts more weight on how quotable your content is and on how consistently your brand is described across the web.
That is why we treat GEO as part of SEO rather than a separate service. A site that is hard to crawl or lacks authority will struggle in both.
What businesses can do now
Start with the questions your buyers ask before they buy, then work through these steps:
- Test those questions in the main AI tools and note who is mentioned.
- Add direct, factual answers to your service and product pages, including definitions, comparisons and FAQs.
- Keep business facts—services, locations, specialisms—consistent across your site, profiles and directories.
- Earn mentions in the publications, reviews and lists that AI tools cite in your sector.
- Use structured data and keep important content in crawlable HTML.
How to measure GEO
Measurement is still immature. Track referral traffic from AI tools in your analytics, run a fixed set of test prompts monthly and record mentions, and ask new leads how they found you. Treat these as directional signals rather than precise rankings.
Frequently asked questions
Is GEO replacing SEO?
No. AI tools rely heavily on search indexes and the same quality signals. GEO extends SEO to a new type of result.
Can anyone guarantee a mention in ChatGPT?
No. AI answers vary by user, wording and time. You can improve the odds; you cannot control the output.
