SEO vs GEO: what UK small businesses need to know
Two goals, one set of foundations
SEO (search engine optimisation) gets your website ranked in a traditional list of search results — the ten blue links under a Google search box. GEO (generative engine optimisation) gets your website read, trusted and cited inside an AI-generated answer from tools like ChatGPT, Perplexity or Google AI Overviews.
They're different goals, but they share almost the same technical foundation: a fast, mobile-friendly, crawlable site with clear structure and real content. If that foundation is missing, neither discipline works.
Where they diverge
| SEO | GEO | |
|---|---|---|
| Goal | Rank in a list of links | Be cited inside a generated answer |
| Primary reader | A search engine's ranking algorithm | An AI model retrieving and summarising content |
| Content style | Keyword-relevant, structured for scanning | Fact-dense, directly quotable, clearly defined terms |
| Success signal | Ranking position, organic traffic | Citation/mention inside an AI answer |
| Maturity | Established practice, ~25 years | Emerging practice, early-stage |
What this means in practice for a UK small business
- Get the technical basics right first. A slow, unclear, JavaScript-only site fails at both SEO and GEO simultaneously — this is the highest-leverage fix available to most businesses.
- Prioritise SEO for volume, today. For most UK small businesses, Google search still sends far more traffic than any AI assistant. Ignoring SEO to chase GEO would be a mistake for almost anyone reading this.
- Layer GEO on top, deliberately. Allow AI crawlers, publish an
llms.txt, and restructure key pages (services, FAQs, about) to state facts plainly and directly. This is a relatively small amount of extra work once the SEO foundation exists. - Treat GEO as a genuine opportunity, not just a hedge. Because almost no small-business competitors have done this yet, doing it properly now is one of the few remaining low-competition opportunities in UK digital marketing.
The bottom line
Don't think of this as a choice between SEO and GEO. Build one well-structured, fast, honestly written website — then make sure both traditional search engines and AI answer engines can read it, trust it, and send people to you.
