What Is Generative Engine Optimisation (GEO)?
GEO is how your business gets cited and recommended by AI search engines: ChatGPT, Perplexity, Gemini, and Google AI Overviews. When someone asks an AI “who’s the best [what you do] in the UK,” GEO is how you become the answer.
Definition
Generative Engine Optimisation (GEO) is the practice of structuring your brand’s online presence so that AI-powered search engines cite and recommend you when users ask relevant questions.
Traditional SEO optimises for Google’s ranked results. GEO optimises for AI-generated answers with citations. The AI engines retrieve information from the web, synthesise it, and cite their sources. GEO is how you become one of those cited sources.
How AI Search Engines Choose What to Cite
Factual Density
Clear, specific, verifiable claims beat keyword-stuffed paragraphs. AI engines want numbers and facts.
Structured Content
Well-organised pages with clear headings and defined sections are easier for AI engines to parse and cite.
Authority Signals
Domain authority, backlink quality, expertise, freshness. Same signals as SEO, still essential.
Uniqueness
If ten pages say the same thing, none stands out. Original data, unique frameworks, and distinctive perspectives get cited.
Entity Recognition
Businesses recognised as distinct entities (consistent naming, structured data, third-party mentions) are more likely to be cited.
GEO vs SEO
| Aspect | SEO (Traditional) | GEO (New Layer) |
|---|---|---|
| Goal | Rank in Google’s results list | Get cited in AI-generated answers |
| Keyword strategy | Exact-match phrase targeting | Topic coverage + entity association |
| Content structure | Optimised for featured snippets | Optimised for extraction: clear claims, structured data |
| Off-site presence | Backlinks for authority | Third-party mentions, directories, industry publications |
| Technical foundation | Site speed, mobile, crawlability | Same + schema markup for AI comprehension |
| What’s new | - | Brand entity development, citation signals, answer-ready content |
Key point: GEO does not replace SEO. It builds on it. Strong SEO foundations make GEO more effective.

Answer-Ready Content
Create permanent reference pages that directly answer the questions your audience asks AI engines. Factually dense, well-structured, unambiguous.
Entity Authority
Build your brand’s recognition in AI knowledge graphs. Consistent branding, schema markup, directory presence, authoritative third-party mentions.
Third-Party Citation Signals
Your presence on industry publications, review platforms, partner pages, and directories directly influences AI engine citations. Quality over quantity.
Structured Data & Technical Foundations
Schema markup (FAQ, Organisation, Service, How-To) helps AI engines understand your pages. Plus the usual: fast, mobile-friendly, fully crawlable.
Freshness & Maintenance
AI engines prefer current information. Review key pages quarterly. Refresh data points. Ensure claims remain accurate.
How to Measure GEO Performance
Brand Mention Monitoring
Track when AI engines mention you in their responses. Manual testing + emerging tracking tools.
Citation Frequency
For your target queries, how often does your content appear in AI answers? Test monthly.
AI Referral Traffic
Google Analytics identifies traffic from ChatGPT, Perplexity, and other AI sources. Growing fast.
Entity Recognition
Ask AI engines about your brand directly. Do they know what you do? Describe you accurately?
Traditional SEO Metrics
Domain authority, organic traffic, keyword rankings. Still underpin everything.
Do It Yourself vs Hire an Agency
Do It Yourself When:
- Strong content team that understands your audience’s questions
- Technical ability for schema markup implementation
- Time to build and maintain content consistently
Hire an Agency When:
- Need a structured strategy and systematic execution
- Lack technical capability for schema and site architecture changes
- Need third-party citation building at scale
- Want to move quickly without the learning curve
Either way, start with an audit. Understanding where AI engines currently mention you (or don’t) is the essential first step.
