GEO Explained
What Is GEO? How Brands Earn Citations and Recommendations in AI Search
Learn what GEO means, how it differs from SEO, why companies, hospitals, and professionals need AI search optimization, and how to measure brand mentions, citations, and recommendations.
Quick answer
GEO is a strategy for organizing information so that generative AI can find and understand a brand and its content, then use them as citations or recommendation candidates when producing answers.
SEO creates a structure for discovery in search results, while GEO creates a structure in which brands are mentioned, cited, and recommended in answers from ChatGPT, Gemini, Perplexity, and Claude.
The starting point is the questions customers actually ask. Create website pages and content that answer those questions, then use the same questions to measure changes in AI answers.
What is GEO?
GEO is a strategy for organizing a website and its information so that a brand and its content can be mentioned and recommended when people ask AI questions.
GEO stands for **Generative Engine Optimization**. The term was introduced in the [original GEO paper](https://arxiv.org/abs/2311.09735), published in 2023, as a method for optimizing content visibility within generative engine answers. The paper was accepted at KDD 2024.
In one sentence, GEO is an information structure that helps a brand be discovered, understood, and recommended within AI answers.
How are GEO and SEO different?
SEO and GEO are not competing approaches. If search engines cannot read a website, AI search will also have fewer public references it can use. SEO builds a foundation for discovery, while GEO strengthens the connection between questions and answers.
| Category | SEO | GEO |
|---|---|---|
| Goal | Make a brand discoverable in search results | Make a brand mentioned, cited, and recommended in AI answers |
| Starting point | Search keywords and search intent | Questions customers enter into AI |
| Primary work | Crawling, indexing, page, and content optimization | Question design, brand information, answer-oriented content, and links to external evidence |
| Measurement | Impressions, rankings, clicks, and conversions | Mentions by question, citations to referenced pages, and inclusion in recommendations |
SEO helps people discover a brand in search results, while GEO helps AI bring that brand forward as a candidate when answering a question.
How does GEO work in practice?
Instead of entering short keywords, users ask complete questions that describe their situations. They ask questions such as **"Where should I get advice about personal rehabilitation?"**, **"What should I look for when choosing a dental clinic for implants?"**, or **"Can you recommend an agency that is good at GEO?"**
From one question, AI expands related considerations such as comparison criteria, location, price, reviews, and expertise to construct an answer. If a brand's official information and expert content are scattered, its name may appear without its strengths and supporting evidence being connected.
| Stage | What the user and AI do | Information GEO should organize |
|---|---|---|
| 1. Question | The user describes a concern and conditions in a complete question | Real customer questions and conditions for comparisons and recommendations |
| 2. Discovery | AI finds official pages and related materials | Brand and service information and expert content |
| 3. Answer | AI compares information and presents an answer and candidates | Clear evidence, cited pages, and external mentions |
Why are companies, hospitals, and professionals turning to GEO now?
AI has moved beyond being a work tool and has become part of everyday decision-making. In [OpenAI's analysis of 1.5 million conversations](https://openai.com/index/how-people-are-using-chatgpt/), about three quarters of consumer conversations involved practical guidance, seeking information, or writing. Across all conversations, 49% were classified as "Asking," meaning that users were seeking guidance or information.
People also ask AI about career choices. In the [JFF 2026 survey](https://info.jff.org/ai-for-workers-learners-2026-survey), 27% of respondents used AI to obtain career guidance, and 14% said AI guidance had a major influence on their career decisions.
AI has also entered the process of finding a hospital. In the [KFF 2026 survey](https://www.kff.org/health-information-trust/poll-1-in-3-adults-are-turning-to-ai-chatbots-for-health-information-equaling-the-share-who-use-social-media-for-health/), 32% of adults in the United States had used an AI chatbot to obtain health information within the previous year. Among them, 41% used AI before deciding whether to visit a health care provider. An [AP report](https://apnews.com/article/ai-chatbots-health-care-poll-0ea249aa0db3fa351efa2a76af3a2348) also described people using ChatGPT to organize their symptoms and questions before scheduling an appointment.
The same pattern applies when people look for a lawyer. The [2026 Legal Consumer Choice Report](https://knowledge.iltanet.org/resource/attorneysync-the-2026-legal-consumer-choice-report) describes how legal consumers first use AI and search to understand their problems, then narrow down lawyers through maps, reviews, and phone consultations. Which companies and professionals appear first in AI answers can therefore influence the initial pool of consultation candidates.
| Audience | Question asked of AI | Information the brand should provide |
|---|---|---|
| Companies | Which solution is right for our company? | Service scope, adoption requirements, comparison criteria, and case studies |
| Hospitals | Which hospital should I visit for these symptoms? | Medical specialties, clinicians, location, care information, and official evidence |
| Professionals | Which lawyer or professional should I consult about my situation? | Areas of expertise, scope of work, consultation criteria, and published cases |
These studies primarily concern users in the United States. We did not convert the figures into estimates for South Korea. They are included as evidence that AI has entered real decision-making processes.
Where should you start if you want AI to recommend your brand?
The first step is not producing a large volume of articles. Start by identifying the questions that reveal what customers compare in a given situation and whom they want recommended.
| Order | Action |
|---|---|
| 1. Design questions | Organize definition, comparison, recommendation, and consultation questions using real customer language |
| 2. Organize the website | Align the relationships among the brand, services, authorship, contact details, and pages |
| 3. Publish content | Answer questions directly and provide comparison criteria and real evidence together |
| 4. Connect external mentions | Use consistent company names and service descriptions across official information and external channels |
| 5. Measure again | Ask the same questions again and record changes in mentions, citations, and recommendations |
How should you evaluate GEO performance?
GEO performance is not complete just because a company name appeared once in an AI answer. Mentions, citations, and recommendations must be recorded separately to reveal which information is missing.
| Metric | Evaluation criterion |
|---|---|
| Mention | Does the brand name or service name appear in the body of the AI answer? |
| Citation | Is the website or its content linked as a reference for the answer? |
| Recommendation | Is the brand included among the candidates in comparison or recommendation questions? |
Record the question wording, platform, measurement date, and login status so that before-and-after results can be compared using the same criteria.

Cross-checks AIGEO measurement results against actual answers generated while logged out and in private browsing mode.
Remeasuring the same questions
Records the question wording, platform, measurement date, and search conditions, then compares before-and-after changes using the same question set.
What should you look at when starting GEO?
Start by entering questions your customers would actually ask into ChatGPT, Gemini, Perplexity, and Claude. Record whether your company name appears, which competitors appear with it, and which pages are cited. This will show your current position.
Next, find the pages on your website that answer the same questions. If no answer exists or company information is inconsistent, start improving those points. GEO is not about operating one more channel. It is the work of connecting customer questions and a brand's official information in a single flow.
What to check when AI recommends your brand
- ✓ Ask the same question several times to see whether the recommendation is repeated.
- ✓ Record brand mentions, citations to referenced pages, and inclusion in recommendations separately.
- ✓ Check whether AI answers match the official website information of the company, hospital, or professional.
- ✓ Record the question wording, platform, measurement date, and search conditions together.
