GEO (Generative Engine Optimization)
GEO (generative engine optimization) is the practice of optimizing your brand and content to be named and cited inside answers generated by AI engines such as ChatGPT, Perplexity, Claude and Google's AI Overviews. Where SEO competes for a ranked list of links, GEO competes to be the source an AI synthesizes into a single answer.
What GEO means
GEO stands for generative engine optimization. A generative engine is any AI system that answers a question by generating text rather than returning a list of links — ChatGPT, Perplexity, Claude, Microsoft Copilot and Google's AI Overviews are the main ones. GEO is the discipline of making your brand the one these engines name, and your pages the ones they cite, when someone asks about your category.
The term emerged as AI answers began absorbing queries that used to end in a Google click. If the answer is delivered directly, the old goal of ranking #1 in a list matters less than being part of the generated answer itself.
How GEO differs from SEO
SEO optimizes to rank in a list of blue links a user clicks. GEO optimizes to be the trusted source an AI uses to make a claim — often with no click at all. The foundations overlap (crawlability, authority, clear structured content), but the unit of success differs: a ranking position versus a citation or brand mention inside an answer.
A practical consequence: you can rank #1 on Google and still be absent from AI answers, because engines lean heavily on third-party sources — reviews, communities, editorial, video — and synthesize from what they trust, not just your page.
How GEO is measured
GEO is measured by two metrics rather than keyword rankings: mention rate (how often an AI engine names your brand for your prompts) and citation share (how often it cites your domain among all sources). You track these across engines and over time, then act on the sources and prompts the data highlights.
Tools like CiteLens run your category's prompts across ChatGPT, Perplexity, Claude and Google AI Overviews, report mention rate and citation share with confidence intervals, and show the sources to win to get into more answers.

Frequently asked questions
What does GEO stand for?
GEO stands for generative engine optimization — optimizing to be named and cited inside AI-generated answers from engines like ChatGPT, Perplexity, Claude and Google AI Overviews.
What is GEO in simple terms?
It's making sure AI assistants recommend your brand and cite your site when people ask questions in your category, instead of only naming competitors.
Is GEO the same as SEO?
No. SEO aims to rank in a list of links; GEO aims to be the source an AI synthesizes into a direct answer. They share foundations but are measured differently — citations and mentions versus keyword rank.
How do I do GEO?
Make your content crawlable and citeable, earn mentions on the third-party sources AI trusts, keep facts clear and current, and measure your mention rate and citation share across engines to guide where you focus.
