Generative engine optimization (GEO) is the practice of making your content citable by AI engines like ChatGPT, Claude, Perplexity, and Gemini. If SEO is about ranking in a list of ten blue links, GEO is about being the source the AI names when it synthesizes an answer.
The short answer
Generative engine optimization is making your site readable and citable by AI answer engines. It includes clear structured content, schema.org markup, an llms.txt file, direct factual assertions, and consistent entity references. Most of it overlaps with strong SEO; the differences are in which signals AI engines weight most.
How GEO differs from SEO
SEO and GEO reward a lot of the same things: authoritative content, technical crawlability, schema markup, internal linking. The differences matter at the margins:
- Citable assertions beat keyword density. "Tool X costs 49 USD a month and supports five platforms" gets cited. "Tool X is a robust solution for teams" does not.
- Entity consistency beats synonyms. SEO rewards varied phrasing (LSI keywords). AI engines reward consistent entity references that let them resolve who or what you are talking about.
- E-E-A-T signals matter more. Author schema, organization schema, and citations to authoritative sources all feed into AI engine confidence scores.
- Long intros hurt more. AI engines skip boilerplate. SEO tolerates it. The first paragraph should be the answer.
The three fastest wins
- Add llms.txt. A short markdown file at
/llms.txtgives AI crawlers a structured summary. See our own llms.txt for an example. - Add Organization and WebSite schema. These anchor your brand as an entity in the AI engine's knowledge graph. Without them, the engine has to guess who you are.
- Rewrite feature pages as direct assertions. Every feature page should open with a one-sentence definition and a three-bullet benefit list. That is what gets lifted into answers.
How to measure GEO
The measurement story is maturing. What works today:
- Manual spot-checks: run your key queries through ChatGPT, Claude, and Perplexity. Look for citations. Track monthly.
- Referrer data: analytics will show traffic from chat.openai.com, claude.ai, and perplexity.ai. The volume is growing quarter over quarter.
- Brand query lift: if AI engines cite you, branded search volume rises. Google Search Console shows this in impressions for your brand keyword.
