What is Generative Engine Optimisation (GEO)?

Generative Engine Optimisation (GEO) is the practice of optimising your website content so that AI-powered search engines — including ChatGPT, Google Gemini, Perplexity AI and Bing Copilot — cite your website in their generated answers.

When someone asks ChatGPT "what's the best accounting software for small businesses?" the AI generates an answer citing specific websites. GEO is the discipline of making sure your website is one of those citations.

Why GEO matters in 2026

The way people search is fundamentally changing. A significant and growing share of all search queries now happen through AI interfaces rather than traditional search engines. Users ask questions conversationally and receive synthesised answers — not a list of links to scroll through.

This shift has enormous implications for website traffic. Websites that AI engines trust and cite gain new, high-intent visitors. Websites that AI engines cannot parse, verify or trust simply don't appear — regardless of their traditional SEO rankings.

The five AI platforms that matter most for GEO are:

• Google AI Overviews — appearing above traditional results for millions of queries
• ChatGPT with web search — used by hundreds of millions of users monthly
• Perplexity AI — the fastest-growing AI search engine
• Google Gemini — Google's conversational AI assistant
• Bing Copilot — Microsoft's AI-integrated search

How GEO differs from traditional SEO

SEO and GEO share foundations — both care about content quality, authority, and technical health — but they differ in what they optimise for.

Traditional SEO optimises for ranking positions in search engine results pages (SERPs). GEO optimises for citation — being the source an AI references when answering a user's question.

Key differences:

• SEO target: Position 1 in Google results. GEO target: Citation in AI-generated answer
• SEO signal: Keyword relevance, backlinks. GEO signal: E-E-A-T, structured data, citability
• SEO outcome: Click to your site. GEO outcome: Brand mention + click to your site

Crucially, GEO does not replace SEO. The two strategies share many optimisation signals and are best pursued together.

How GEO works: the 8 key criteria

GeoLens measures AI search visibility across 8 criteria, each weighted by its impact on AI citation likelihood:

2. Brand Authority Signals (20%) — Does your brand appear trustworthy to AI systems?
3. Content Quality & E-E-A-T (20%) — Does your content demonstrate real expertise and experience?
4. Technical Foundations (15%) — Is your site technically sound enough for AI crawlers?
5. Structured Data (10%) — Have you implemented schema markup that AI can read?
6. Platform Optimisation (10%) — Are you optimised across different AI platforms?
7. Page Authority & Backlinks — Does your page carry sufficient authority?
