What is Generative Engine Optimization?

Generative Engine Optimization (GEO) is the practice of making your brand easier for AI assistants such as ChatGPT, Perplexity, Gemini and Claude to find, understand and cite. Instead of ranking a link, the goal is to be one of the brands the assistant names when it answers a buyer's question.

Search used to return ten blue links. AI assistants return a single synthesized answer that names a few brands and cites a few sources. GEO covers the work that makes your brand and your pages available and clear to those systems, the way SEO covers the work for search rankings.

Why does GEO matter now?

Part of buyer research now happens inside AI assistants. When an answer names competitors and not you, a buyer may shortlist them before visiting any website. How much this matters varies by category, so measure it for your own questions.

Comparison and shortlist questions, common for software and other considered purchases, are where answers tend to name a few brands. If your brand is absent from those answers, buyers who rely on them may not consider you.

How is GEO different from SEO?

SEO works on a ranked list of links a person clicks. GEO works on a single AI-generated answer where the assistant chooses which brands to name and which sources to cite. The signals overlap but differ: an answer draws on several sources, so how other sites describe your brand can matter alongside your own pages.

There is overlap: clean structure and authoritative content help both. GEO adds its own levers: concise answer passages an assistant can quote, question-style headings that match how prompts are phrased, structured data that matches the page, and brand mentions on trusted sources and forums.

How do you work on GEO?

Common steps: measure how assistants answer your buyers' questions, publish clear and well-structured answers on the questions where competitors appear and you do not, and earn mentions on trusted third-party sources. None of these steps guarantees a citation.

• Measure: send a stable set of category questions to the assistants and record whether you're mentioned and cited.
• Structure: lead each section with a concise answer under a question-style heading; add tables and FAQs.
• Earn mentions: original data and coverage on independent sites and forums give assistants more sources that describe your brand.
• Repeat: re-measure on a stable schedule and update pages when facts change.

Can you measure GEO?

Yes, by sampling. Run a fixed set of buyer questions through each assistant on a schedule and record whether your brand is mentioned, in what position, and whether your site is cited as a source, then compare the results over time.

Paid GEO tools do this at different volumes and frequencies. Citanto, for example, sends a fixed panel of 15 or 30 questions to four engine APIs each month and prepares content drafts for your review.
