GEO: Getting Cited by ChatGPT & Perplexity
Generative engines like ChatGPT, Gemini and Perplexity answer in prose and cite sources. GEO is the practice of becoming one of those cited, recommended sources.
What generative engines reward
Studies of AI citations point to a consistent pattern. Generative engines favour content that is factual and specific (numbers, dates, named entities), clearly structured, shows genuine expertise, and is widely referenced across the web. Being mentioned on other reputable sites (even without a link) increases how often an LLM names you.
A practical GEO checklist
- Be quotable — include clear statistics, definitions and takeaways an LLM can lift.
- Be an entity — consistent name, About page, Organization schema, presence on trusted sites.
- Be current — update key pages; AI favours fresh, accurate information.
- Earn mentions — PR, guest content and citations build the “everyone references them” signal.
- Allow the crawlers — do not block GPTBot, Google-Extended, PerplexityBot in robots.txt if you want to be cited.
Ask Perplexity a stats question. It cites the page that states a specific figure with a clear source — not the vague competitor. Specificity and credibility are what get you named.
