Key takeaways
- In AI search, what matters is not the top position but which brands AI mentions, which information it trusts and which pages it cites.
- GEO builds on SEO. AI Overviews and AI Mode run on Google’s existing crawling, indexing and quality systems, so the basics still apply.
- Start from the questions customers ask AI, not from keywords. Questions without a brand name matter most.
- Measure mentions and citations separately. A brand can be named while a competitor’s page is cited.
- GEO is a program, not a project: measure, discover, create, distribute, measure again.
What matters in this change is not simply appearing at the top of a results page. It is which brands AI mentions, which information it trusts, and which pages it cites as evidence. Generative Engine Optimization, or GEO, is the practice of managing exactly that. This guide explains how your brand is discovered, mentioned and cited in AI search, and how to improve it step by step.
Search is not disappearing. It is changing.
Google has said that AI Overviews reach more than two billion monthly users and that AI Mode has passed one billion. AI search is no longer an experiment for a few users. It is becoming the main interface of the search experience.
Behaviour is changing too. In March 2025 the Pew Research Center analysed the real Google searches of about 900 US adults. When an AI summary appeared, 8% of searches ended in a click on a regular result. Without a summary, the figure was 15%. Clicks on the source links inside the summary itself were about 1%.
How the search experience changes
| Traditional search | AI search |
|---|---|
| Type a keyword | Ask a question in natural language |
| Compare ten results | AI combines the information |
| Visit websites yourself | Consume the information inside the answer |
| Compete for a ranking | Compete to be included in the answer |
| Clicks are the main KPI | Mentions, citations, recommendations and clicks are the KPIs |
| SEO | SEO plus GEO |
Being first on the results page is no longer enough. You have to be the information AI selects when it writes the answer.
Chapter 1. Understanding GEO properly
What GEO is
GEO stands for Generative Engine Optimization. In plain terms, it is the process of making sure that when a customer asks AI about your product or your market, your brand and your content are found accurately, mentioned, and cited as a trustworthy source.
SEO aimed for a high position on a search engine’s results page. GEO aims for presence inside the answers that ChatGPT, Gemini, Google AI Mode and Perplexity generate. GEO does not replace SEO. Google states that AI Overviews and AI Mode run on the same crawling, indexing and quality systems as Google Search, so the fundamentals of SEO still matter.
How SEO and GEO relate
| Area | SEO | GEO |
|---|---|---|
| Main target | Google and Naver search | ChatGPT, Gemini, AI Mode, Perplexity |
| User behaviour | Keyword search | Questions in natural language |
| Unit of competition | Search ranking | The AI answer |
| Core outcome | Ranking, CTR, traffic | AI mentions, citations, recommendations, accuracy |
| Main content | Keyword-centred pages | Questions, answers, comparisons, expert information |
| How authority is judged | Links, domain, content | Search authority plus external sources plus consistency |
| Measurement | Search ranking | AI Visibility and Citation Share |
How AI builds an answer
AI search does not look up a single keyword. Google explains that AI Mode breaks a complex question into several sub-questions and searches them at the same time, a method it calls query fan-out.
From question to cited answer
- The question. “Recommend an affordable skincare brand for sensitive skin.”
- Query fan-out. Products for sensitive skin, low-irritant ingredients, price comparison, user reviews, dermatologist recommendations, brand reputation.
- Retrieval. Brand sites, news articles, specialist sites, reviews, communities, shopping data.
- Comparison and verification. Relevance, trustworthiness, freshness, consistency across sources.
- The answer. Brand A, Brand B, Brand C.
- Citations. Articles, brand sites, reviews, expert material.
So what counts is no longer how often one keyword repeats on one page. It is how well you explain the whole topic.
The four things that matter in GEO
- Can it be found? AI and search engines must be able to crawl and index the page normally.
- Can it be understood? Information about the company, products, services, prices, customers and differences must be clear.
- Can it be trusted? Evidence is needed: numbers, research, customer cases, expert opinion, external sources.
- Is it easy to cite? Sentences that answer the question directly, tables, comparisons, statistics and a clear structure.
A GEO study presented at KDD 2024 reported that some techniques, such as adding citations, statistics and quotations, improved visibility in generative search by up to about 40% in an experimental setting. That is a benchmark result, not a promise that a live service will show the same gain.
Chapter 2. A brand AI can understand
The first task in GEO is not producing a lot of content. It is deciding what your brand should be remembered for. AI understands a brand by combining everything that exists about it on the web. If the website says “AI marketing company”, the press release says “marketing automation solution” and LinkedIn says “GEO platform”, AI finds it hard to understand the brand clearly.
Define the core message
You should be able to answer four questions in one sentence each.
| Question | Example |
|---|---|
| Who are we? | An AI search and marketing optimization platform |
| Whom do we help? | Companies that want to win customers in the age of AI search |
| What problem do we solve? | A brand that is invisible in AI answers |
| What result do we create? | More AI Visibility and more citations |
A good brand message is concrete rather than abstract. “An innovative AI company” says little. “A platform that analyses and improves a company’s brand exposure and citations in AI search” is a sentence AI can understand and reuse as it is.
Claims need evidence
For AI to trust a brand, every claim should sit next to its evidence.
| Claim | Evidence |
|---|---|
| Customers are satisfied | Customer satisfaction 94% |
| We are growing fast | Customer count up 180% year on year |
| We are experts | Years in the field, patents, papers, awards |
| Customers get results | Before-and-after data, case studies |
Where you can, leave information on the web in this shape: number, source, date, subject, result. “We improve customers’ AI search exposure” is weak. “After GEO optimization, brand mentions for Company X on its key AI questions rose from 18% to 37% over 12 weeks” is strong.
Build pages AI can read
Google recommends keeping important content as text rather than only inside images, and keeping the search basics in place: crawlability, internal links, page experience and accurate structured data. Google also states that no special schema or AI-only file is required to appear in AI search features. Before any “AI trick”, make the website itself a clear and trustworthy source of information.
Chapter 3. Design questions, not keywords
In SEO the keyword was the starting point. In GEO the starting point is the prompt: what customers actually ask AI. Imagine someone buying a coffee machine.
The two are completely different. An AI prompt carries price, user, situation, purpose and conditions at the same time.
Questions change along the customer journey
| Stage | Customer question |
|---|---|
| Problem awareness | Why does coffee at home never taste like the café? |
| Exploration | What kinds of home coffee machines are there? |
| Comparison | Fully automatic or semi-automatic, which is easier? |
| Shortlist | Recommend a fully automatic machine under one million won |
| Decision | Between product A and product B, which is easier to maintain? |
| After purchase | How often should product A be cleaned? |
In GEO, questions without a brand name matter more than questions with one. Before a customer asks “What is flowgen like?”, they ask “Why doesn’t our company show up in AI search?”.
Build a prompt universe
A useful structure is Topic → Persona → Intent → Funnel → Prompt. For example: topic, AI search optimization; persona, marketing manager; intent, solve a problem; funnel, consideration; prompt, “Why do competitors appear in ChatGPT and we don’t?”. Managed this way, prompts stop being a list of questions and become data that shows the real buying journey.
Chapter 4. Your first GEO audit
GEO should not be judged by feel. Measure the current state first. A GEO audit checks five areas.
| Area | Core question |
|---|---|
| Visibility | Does AI mention our brand? |
| Citation | Is our website cited as evidence? |
| Accuracy | Does AI describe our company correctly? |
| Competitive gap | Which questions name competitors but leave us out? |
| Opportunity | Which questions does no brand own strongly yet? |
AI Visibility
This is the most basic measure: the number of answers that include the brand divided by the number of relevant answers measured. Do not stop at one average. Split it by platform (ChatGPT, Gemini, Google AI Mode, Perplexity) and by question type (product, price, comparison, recommendation, problem solving).
Citation Share
A brand being mentioned does not mean its content was cited. AI can say “Brand X is a good choice” while using a competitor’s article or a news story as evidence. Measure mentions and citations separately.
| High citation | Low citation | |
|---|---|---|
| High mention | Stronghold | Visible but not cited |
| Low mention | Cited but not visible | Opportunity |
- Stronghold must be defended.
- Visible but not cited means the brand is known, but your own content carries little authority.
- Cited but not visible means the content is useful, but the link between the brand and the information is weak.
- Opportunity needs both content and external authority.
AI visibility tools such as Profound’s Answer Engine Insights also measure visibility and citation share separately and combine the two axes to rank topics.
Find the competitive gaps
The most valuable output of an audit is not “our score is 37”. It is a list of questions like these: questions where competitors appear and you do not; questions where the information about your product is wrong; questions where AI quotes an old price or a retired product; questions where only one publisher or community is cited again and again; questions no brand has clearly claimed. These become the actual tasks.
Chapter 5. Building a GEO strategy
Once the audit is done, connect the findings to content. The point is not to edit every page, but to solve the most valuable questions first.
On-page GEO
Strengthen the information on your own site that AI could cite. Good GEO content is not good because it is long. It is good because the answer is easy to find, the evidence is clear and the structure is easy to follow. Profound’s analysis of about two thousand pages reported that content with tables and clear structure correlated with AI citations. That is a vendor study rather than independent research, but it is a useful reference for structuring content.
A content structure that is easy to cite
- The question
- A one-sentence answer
- The key evidence
- Statistics or data
- A comparison table
- A real example
- FAQ
- Sources
This structure is easy for people to read and easy for AI to extract from.
Off-page GEO
AI does not read only your homepage. It also draws on news, industry media, associations, government bodies, review sites, communities, YouTube and expert content. GEO therefore does not end on your website. The key claims about your brand must be confirmed consistently outside it. If your site claims “first in Korea” and no independent source confirms it, AI is less likely to repeat the claim. If the same information exists alongside credible industry articles, research, interviews and customer cases, the web of information AI can draw on becomes far richer.
What to do first
| Small gap | Large gap | |
|---|---|---|
| High-value question | Maintain | Top priority |
| Low-value question | Later | Review |
Rank by question importance times the current visibility gap times the influence on purchase. Do not simply fix every question with low AI Visibility. Fix the questions that lead to customers first.
Chapter 6. Keeping GEO growing
GEO is not a project that ends after one round of site changes. AI models, search results, competing content and customer questions keep changing. Like SEO, content marketing and PR, GEO is a program that runs continuously.
The GEO cycle
Measure, discover, create, distribute, measure again
- Measure. AI Visibility, citations, sentiment, competitors.
- Discover. Prompt gaps, content gaps, citation gaps.
- Create. New content, page improvements, FAQs, comparisons.
- Distribute. Website, PR, blog, social, communities.
- Measure again, and repeat.
A GEO KPI dashboard
| KPI | What it means |
|---|---|
| AI Visibility | Share of relevant AI answers that include the brand |
| Share of Voice | Share of mentions against competing brands |
| Citation Share | Share of all citations that point to your site |
| Citation Coverage | How many questions cite you |
| Accuracy | Share of answers that describe the brand correctly |
| Sentiment | How AI answers evaluate the brand |
| Competitive Gap | Questions where you trail competitors |
| AI Referral | Site visits that came from AI services |
| Conversion | Enquiries and purchases from AI-referred visitors |
In the age of AI search, traffic alone is a poor measure of results. Brand comparison and shortlisting can happen inside AI before anyone visits the site.
A 90-day GEO roadmap
| Weeks | Main work |
|---|---|
| 1–2 | Define the brand and the competitors |
| 2–3 | Build the core prompt universe |
| 3–4 | Measure the AI Visibility baseline |
| 4–5 | Analyse citation and competitor gaps |
| 5–8 | Improve the key pages for GEO |
| 6–10 | Create new content, comparisons and FAQs |
| 7–12 | Earn external citations, PR and distribution |
| 12 | Re-measure and choose the next priorities |
The one principle to remember
The purpose of GEO is not to trick AI. It is to make your brand a trustworthy source when AI composes a good answer for a customer. Good SEO and good GEO point the same way: accurate information, original information, verifiable evidence, clear structure, fresh information, trustworthy sources. Google, too, emphasises the existing quality principles of search and valuable original content over any special trick for AI search.
The next step after SEO is GEO
Customers used to discover brands on a results page. Now they ask AI: “Which company is best?”, “Which product should I buy?”, “A or B?”, “Recommend a solution that fits our company.” If your brand does not appear in those answers, you may lose the chance to be considered at all. flowgen analyses how AI understands your brand and connects discovery, analysis, improvement, distribution and measurement into one loop.
