## 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.

## What this means in practice for a UK small business

1. **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.
2. **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.
3. **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.
4. **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.
