What Is Generative Engine Optimization (GEO)? How to Get Cited by AI Search
AI assistants now answer many of the questions buyers used to search for. Here’s what GEO is, how it differs from SEO and the practical steps to get your brand cited.
Generative engine optimization (GEO) is the practice of making your content, brand and data easy for AI systems — such as Google AI Overviews, ChatGPT, Perplexity, Gemini and Microsoft Copilot — to understand, trust and cite in their answers. Where SEO aims for ranking positions, GEO aims for being the source an AI assistant quotes or recommends.
Why GEO matters now
A growing share of research starts with a question typed or spoken to an AI assistant. These systems retrieve a handful of sources, summarise them and sometimes cite them. If your brand is not among those sources, you can be invisible even when you rank well in traditional results.
GEO vs SEO: what’s different?
- Unit of success: SEO measures rankings and clicks; GEO measures mentions, citations and how accurately you are described.
- Content shape: GEO rewards concise, self-contained answers, definitions, comparison tables and FAQs that can be lifted into a response.
- Entity clarity: AI systems rely on consistent facts about who you are and what you do across your site and the wider web.
- Third-party signals: reviews, directories, communities and publications strongly influence which brands AI recommends.
Seven practical GEO steps
1. Lead with the answer
Open important pages with a two- or three-sentence answer to the main question, then expand. This is the passage most likely to be quoted.
2. Add structured data
Use schema.org markup — Organization, Service, Product, Article, FAQPage and BreadcrumbList — so machines can parse your facts reliably.
3. Write FAQs and comparison tables
Questions phrased the way buyers ask them, with direct answers, map neatly onto AI prompts.
4. Publish an llms.txt file
An llms.txt file at your domain root gives language models a curated summary and map of your most important pages. It complements your sitemap and robots.txt.
5. Allow the right AI crawlers
Check that your robots.txt does not accidentally block the search and assistant crawlers you want to be cited by.
6. Strengthen your entity across the web
Keep your name, description and key facts consistent on your site, social profiles, directories and review platforms.
7. Measure AI visibility
Track a fixed set of buyer prompts across AI platforms each month and record whether you are mentioned, cited and described correctly.
How to get started
Start with your highest-value pages: rewrite the opening for clarity, add FAQs and schema, publish llms.txt and set up monthly prompt tracking. If you need dedicated help, a GEO expert or SEO expert can run this process for you full-time.
