What Is GEO? The Portsmouth Business Owner's Guide to AI Search

If you've ever asked ChatGPT to recommend a plumber, a restaurant, or a web designer — you've already seen Generative Engine Optimisation (GEO) in action. Or more precisely, you've seen what happens when a business hasn't invested in it.

SEO vs GEO — What's the Difference?

Traditional SEO focuses on ranking in Google's blue-link results. It's about keywords, backlinks, and meta tags. GEO goes further. It's about making your business visible in AI-generated answers — the kind that appear in ChatGPT, Google AI Overviews, Gemini, Perplexity, and voice assistants like Siri and Alexa.

When someone asks "Who's the best accountant in Southsea?", AI doesn't just return a list of links. It recommends specific businesses. If yours isn't one of them, you're invisible to a rapidly growing segment of searchers.

Why GEO Matters for Portsmouth Businesses

Portsmouth and the wider Solent region are home to thousands of small businesses competing for local customers. As AI search adoption grows, the businesses that appear in AI answers will capture an outsized share of enquiries.

Consider these trends:

• ChatGPT now has over 200 million weekly users worldwide
• Google AI Overviews appear on an increasing number of search results
• Voice search via Siri, Alexa and Google Assistant continues to grow — and voice answers are almost always AI-generated

If your website doesn't provide the structured data, authority signals, and clear content that AI models need, you simply won't be recommended.

How GEO Works in Practice

GEO optimisation involves several key areas:

1. Structured Data (Schema Markup) — JSON-LD schema tells AI exactly what your business does, where you're located, and what services you offer
2. E-E-A-T Signals — Experience, Expertise, Authoritativeness, and Trustworthiness. AI models favour businesses with clear credentials and social proof
3. Content Structure — Clear headings, FAQ sections, and well-organised content make it easier for AI to extract and cite your information
4. Local Signals — Consistent NAP (Name, Address, Phone) data, Google Business Profile optimisation, and local citations
5. Technical Health — Fast load times, mobile-friendly design, HTTPS, and clean code
