What is GEO (Generative Engine Optimization)?
GEO is Generative Engine Optimization — getting your content cited and quoted by AI answer engines like ChatGPT, Google AI Overviews, Perplexity and Gemini. Learn what these engines favour and how to become a trusted source.
Generative Engine Optimization (GEO) is the practice of optimising content so generative AI engines — ChatGPT, Google's AI Overviews, Perplexity, Gemini, Claude and others — surface and cite it in their answers.
AI search summarises sources rather than just listing links, so the goal shifts from 'rank #1' to 'be the source the AI quotes and attributes'.
What generative engines favour
Research and practice point to a consistent pattern. AI engines preferentially cite content that is:
- Clearly written and well-structured, with descriptive headings
- Stat-dense and specific — exact figures, dates and named sources
- Authoritative and trustworthy (clear authorship, citations, freshness)
- Answer-first, so a clean statement can be lifted and attributed
- Machine-accessible (crawlable HTML, structured data, and an llms.txt)
Be the citable source
Make each important fact a self-describing unit: state the figure, the as-of date and the primary source in one place. AI engines quote sentences they can attribute confidently.
Help AI crawlers find you
Allow modern AI crawler user-agents in robots.txt, publish an llms.txt that points to your best content and canonical figures, and use entity-typed schema (Place, Organization, DefinedTerm, Dataset) so engines understand exactly what your page is about.
Key takeaways
- ✓GEO = getting cited and quoted by AI answer engines.
- ✓Favour clear structure, exact stats with dates and named sources.
- ✓Use answer-first writing so facts are easy to lift and attribute.
- ✓Allow AI crawlers and publish an llms.txt + entity schema.
What is GEO (Generative Engine Optimization)? Ranking in AI Search — FAQ
Is GEO different from SEO?+
It overlaps heavily but optimises for AI citation rather than a ranked link. Good SEO foundations (crawlability, structure, authority) are prerequisites for GEO.
How do I get cited by ChatGPT or Perplexity?+
Publish accurate, well-structured, frequently-referenced content; mark up facts with schema; keep figures dated and sourced; allow AI crawlers; and build off-site authority so engines trust you.
What is llms.txt?+
A plain-text file at your domain root that guides AI/LLM crawlers to your most important content and canonical facts — see the dedicated guide.
