What Is Generative Engine Optimisation (GEO)? A Plain-English Guide
If you’ve heard the term Generative Engine Optimisation (GEO) floating around and aren’t sure whether it’s just SEO with a new name, here’s the direct answer: it’s related, but it’s not the same thing — and the difference matters for how customers find your business today.
The direct definition
Generative Engine Optimisation is the practice of structuring your website, content and data so that AI systems — ChatGPT, Gemini, Perplexity, Copilot — cite your business directly inside their generated answers, rather than only listing your site as one of ten blue links.
Here’s the practical difference: when someone types “best SEO agency” into Google, they get a page of results to browse and compare. When they ask the same question to ChatGPT, they get one written answer, usually naming two to four specific companies. If your business isn’t one of them, you simply don’t exist for that person — even if you rank well in traditional Google search.
Why this matters right now
The habit of asking an AI directly, instead of searching and comparing links, is growing fast — particularly for commercial research (choosing a service provider, comparing options before a purchase decision). That’s exactly the kind of query that used to be pure SEO territory.
Most businesses haven’t done anything specific for this yet, which means there’s a genuine window to build visibility before the space gets crowded.
How AI models decide who to cite
Generative engines don’t invent the brands they recommend — they draw on real signals already present across the web:
- Clear, well-structured content that directly answers the questions your customers are actually asking
- Structured data (schema.org markup) that helps the model understand exactly what your business does and offers
- Genuine mentions and citations from other trusted sites — not just your own marketing copy
- An
llms.txtfile, a simple text file that acts as a map of your brand for AI crawlers
Does GEO replace traditional SEO?
No. GEO builds on top of SEO, it doesn’t replace it. The technical foundation — a fast, well-structured, authoritative site — is exactly the same foundation both disciplines need. What changes is how content is written and structured so it’s easy for an AI model to extract, summarise and cite correctly, not just index.
Where to start
- Make sure your site has real, specific content about what you actually offer — not just generic “About Us” copy
- Add structured data (schema.org) to your key service pages
- Publish an
llms.txtfile explaining who your business is, in plain language a model can parse - Build genuine third-party mentions and citations — this still matters as much as it always did for authority
