What is GEO?

What it means

Generative Engine Optimization (GEO) is the practice of shaping content, brand presence, and entity information so that AI answer engines, ChatGPT, Gemini, Perplexity, Claude and Grok, mention, cite, or recommend a brand when they answer a question. Where a traditional search engine returns a ranked list of links, a generative engine synthesizes one answer and names a handful of sources inside it. GEO is the work of earning a place among those sources.

Why it is different

A generative engine does not rank pages the way a search engine ranks a results page. It draws on what it learned during training and, increasingly, on live retrieval, then composes an answer in its own words. Signals built for ranking a page carry over only loosely. What tends to make a brand more likely to be cited is different:

• Authoritative content that answers a real question clearly and directly, rather than content built primarily to rank.
• Consistent entity information: the same brand, product, and category description wherever it appears online, so an engine can resolve who is being talked about.
• Third-party mentions and citations on other reputable sites, which build a model's confidence in a source.
• Freshness and coverage of the questions buyers actually ask, not just the keywords they type.
• Machine-readable structure: schema markup, clear headings, and concise, self-contained answers an engine can lift directly.

A mention and a citation are not the same outcome, and GEO work can move one without the other.

What it looks like

Someone asks an assistant a direct question, "what's the best invoice software for a small agency?", and gets back one answer that names a couple of tools rather than a page of results. GEO is the ongoing work behind earning a spot in that answer: finding the high-intent questions where competitors are cited and a brand is not, publishing clear and direct answers to those questions, and rechecking regularly, since which sources get cited shifts every time the underlying models update.
