In short
GEO (Generative Engine Optimization) is the practice of making your brand the source generative AI engines pull from when answering a buyer's question. It overlaps with AI SEO and LLM SEO but focuses specifically on optimising for generative output: clear entity signals, structured data, direct answers, original research, and citation density across third-party sources.
GEO, AEO, AI SEO — what's the difference?
These terms overlap heavily and most agencies use them interchangeably. The useful distinctions: AEO (Answer Engine Optimization) focuses on direct-answer formats — featured snippets, AI Overviews, FAQs. GEO focuses on being cited by generative engines — ChatGPT, Perplexity, Gemini, Copilot. AI SEO is the broader umbrella that includes both. All three rely on the same fundamentals.
What generative engines reward
Generative engines compose answers, so they prefer sources that compose well — pages with clear claims, structured evidence, defined entities and easy-to-lift quotes.
- Clear, declarative answers in the first 100 words
- Defined entities with schema and sameAs links
- Original data, surveys or proprietary research
- Citations to authoritative third-party sources
- Consistent brand identity across the open web
The GEO playbook
Start with an audit: run 30–50 buyer prompts through ChatGPT, Perplexity and Gemini and log which competitors are cited. Then rewrite your most commercial pages with answer-first structure and FAQ schema. Build entity authority by anchoring your brand on Wikidata, LinkedIn, Crunchbase and trusted industry directories. Earn citations through original data and digital PR. Track citation share of voice monthly.
What GEO is not
GEO is not stuffing pages with 'as an AI engine' phrases. It is not adding hidden text or schema you don't actually deliver. Generative engines are increasingly good at detecting manipulation, and the cost of being delisted from AI answers is much higher than from search rankings.
How to measure GEO progress
Citation share of voice across AI engines, branded prompt visibility, AI Overview placements, and downstream AI-referral traffic in GA4. Most brands also tie GEO progress to qualified-meeting volume — citations are upstream of pipeline.
