What is GEO?

Generative engine optimization (GEO) is the work of making a business easy for AI tools such as ChatGPT, Google's AI Overviews, Gemini and Perplexity to find, understand and describe accurately when they answer a question. SEO aims to rank a page in a list of links. GEO aims for your business to be represented correctly in the answer itself.

Where the term comes from

The term was introduced in a 2023 research paper by Pranjal Aggarwal and colleagues, published at the KDD 2024 conference. It describes generative engines, systems that write an answer from many sources instead of returning a list of links, and studies how content creators can improve how visible their content is in those answers.

For a business, the practical question is simpler: when a customer asks an AI tool for a recommendation or an explanation, is your business part of the answer, and is it described correctly?

Why it matters now

AI answers now sit at the start of many searches. At Google I/O in May 2026, Google said AI Overviews has more than 2.5 billion monthly active users, and that AI Mode has passed 1 billion.

When the answer is already on the page, fewer people click through. In a Pew Research Center study of the Google searches of 900 US adults in March 2025, 18% of searches produced an AI summary. On those pages, people clicked a traditional result on 8% of visits, compared with 15% on pages without one, and clicked a link inside the summary on just 1% of visits.

The answer itself increasingly shapes the first impression of your business, often before anyone opens your website.

GEO and SEO compared

GEO and SEO share their foundations. Google states that the same requirements apply to its AI features: a page has to be indexed and eligible to appear with a snippet in Search, and no special files, markup or structured data are needed. The difference is in what you aim for, and how you measure it.

SEOGEO
The aimA page ranks well in a list of resultsYour business is named, described accurately and cited inside an answer
What the searcher seesTitles, snippets and links to choose fromA written answer, often with a few linked sources
FoundationsThe same: pages that can be crawled, indexed and shown with a snippet, with clear titles and content in the HTML
Sources that countMainly your own pagesYour pages, and the directories, reviews, press and forums the answer draws on
How it is measuredRankings, impressions and clicks (Search Console, Bing Webmaster Tools)Whether you are mentioned, how you are described, and whether your pages are cited (a question log; Bing's AI Performance report for Copilot)
How stable it isRankings move graduallyAnswers vary between runs, tools and languages, so trends matter more than one result

A business with strong SEO has a head start in GEO. It still needs to check what AI tools actually say, because an answer can be built from many sources besides its own website.

How AI search finds and cites sources

Each AI search tool reads the web through its own crawler or search index, and each lets site owners control access separately from AI training. What the platforms document:

ToolHow it reads the webHow sources appearWhat a site owner controls
Google AI Overviews and AI ModeGoogle's Search index, crawled by Googlebot. Both may use "query fan-out", running several related searches across subtopicsLinks to supporting websites; AI Overviews appear only when Google judges them additive, so they often do notGooglebot access, and nosnippet, data-nosnippet, max-snippet or noindex. Google-Extended affects Gemini training and grounding, not Search
ChatGPT searchOAI-SearchBot, OpenAI's search crawlerWebsites surfaced in the search results of ChatGPT's answersAllowing OAI-SearchBot; opted out sites are not shown in answers, though they can still appear as navigational links. GPTBot (training) is set separately (OpenAI)
Microsoft Copilot and BingBing's index; Bing describes Copilot experiences as powered by BingCitations shown as sources in AI generated answersrobots.txt and data-nosnippet, which Bing honours in snippets and AI summaries; citations reported in AI Performance
PerplexityPerplexityBot, which surfaces and links websites in results; Perplexity-User fetches a page when a person asksLinked sources in each answerAllowing PerplexityBot in robots.txt. Perplexity says the user requested fetcher generally ignores robots.txt (Perplexity)
ClaudeClaude-SearchBot indexes pages for search; Claude-User visits a page when a person asksResults in Claude's web search for the people using itEach agent separately in robots.txt; ClaudeBot is the training crawler (Anthropic)

The pattern is consistent: allowing the search crawlers keeps a site eligible to be read and cited, and blocking a training crawler does not remove it from search answers. Google’s own advice for its AI experiences is the same as for Search: make sure Googlebot is not blocked, and write for people.

Mentions, citations and recommendations

When you check what AI says about your business, three different outcomes are easy to confuse. They mean different things, and they are recorded differently.

OutcomeWhat it looks likeWhat it tells youHow to record it
Brand mentionThe answer names your business in its textThe tool knows you exist and connects you with the topicNamed: yes or no, and the exact description used
Linked citationOne of your pages is shown as a source, with a linkYour website informed the answer, and the reader has a route to itWhich page was cited, and for which claim
RecommendationAsked who to choose, the answer suggests your businessYou are on the shortlist for a buyer's questionPosition in the list, the reason given, and who else is named

A business can be mentioned without being cited (the tool relied on a directory), cited without being recommended (your page explained a topic), or recommended on the strength of other sites’ descriptions. Each points to different work.

How Glowtice assesses AI visibility

When we look at how AI tools present a business, we ask four questions, in this order. It is a working method for finding what to fix, not a validated scoring model, and it uses nothing more than the tools your customers use and careful reading of what they say.

Take a question a buyer might ask:

1. Does the business appear for relevant buyer questions?

What we examine. The questions a real buyer would ask before choosing: questions about the service, about a type of customer, and comparisons. We ask them in the language buyers use, and note whether the business is named at all.

What a problem looks like. The business appears when asked about by name, but not for the questions that bring new customers. Or it appears for one service and is missing for another it offers.

What may help. First make sure the website can be read and has one clear page per service. Then look at the sources the answers do cite: if every answer leans on a few directories or articles, being accurately present there matters.

2. Is it described accurately?

What we examine. Every factual detail in the answer: name, services, location, hours, contact details, who the business serves.

What a problem looks like. An old address, a service the business no longer offers, a specialism it never had, or a summary so general it could describe any competitor.

What may help. Find where the wrong detail comes from. Often it is an outdated listing, an old page that is still online, or a profile nobody maintains. Correct it there, because correcting your own website alone may not change answers built on the other source.

3. Does the answer explain why the business fits the buyer’s needs?

What we examine. Whether the answer says what makes this business suitable for this buyer: the specialism, the type of client, the language, the hours, the area served.

What a problem looks like. The business is named, but only in a list, with nothing that would make the buyer choose it over the next name.

What may help. State the facts that decide a choice plainly, in text, on the relevant page: who the service is for, what is distinctive about it, and the practical details that matter to that customer.

4. Which sources support the answer?

What we examine. The pages each answer links to, and whether they actually support what the answer says about the business.

What a problem looks like. The answer about the business cites only third party pages, so the business’s own website does not inform how it is described. Or a cited page does not contain the claim attached to it.

What may help. Make your own pages the clearest, most complete source on your business, and keep the third party sources that answers rely on accurate. Where a citation does not support the claim, that is a reason to check the answer more carefully, not to trust it.

From a vague description to useful business information

Many business descriptions are written to sound impressive rather than to be understood. A buyer comparing options, and an AI tool answering a specific question, both need the same thing: what the business does, for whom, what it can handle, and what supports its claims. Two illustrative examples, from different industries:

“Award winning” and “innovative” cannot be checked, and they do not match any question a homeowner asks. The revised version can be matched to a real question, such as an architect for a house extension who also handles planning, and every claim in it points to something a reader can verify.

A buyer’s question is rarely “who is a trusted technology partner?”. It is closer to “who can look after IT for a twenty person office that uses Microsoft 365?”. The revised version contains the facts needed to answer that question, and to judge whether the company fits before contacting it.

These examples are for illustration. They show how to write clearer information; they do not report the results of any change.

How to decide what to improve first

An assessment usually turns up several problems at once. These are diagnostic starting points, not explanations of why a particular tool did or did not name a business: AI tools do not explain, for a given answer, why one business was included and another was not. The order reflects what tends to cost a business most, and what other fixes depend on.

What you findWhat it looks likeNext actionWhy this comes first
Incorrect business informationA wrong address, number, service or hours in an answer or in a source it citesCorrect it where it originates: your website first, then each listing or profile the answers rely onWrong facts mislead buyers who are ready to act, and every answer built on that source repeats them
Conflicting information across sourcesThe website, listings and profiles disagree on the name, services, hours or contact detailsDecide the correct version once, then make every source match itCompeting versions leave a tool to choose between them; consistency removes the doubt before anything new is added
Missing service or audience detailsAnswers describe the business vaguely, or for the wrong kind of customerState on each service page what the service is, who it is for, where it is offered and how to startAn answer can only reflect what is written somewhere; a page that never says who it is for gives nothing to match a buyer's question
Unsupported claims"Leading", "best" or "award winning" with nothing named to support itReplace each claim with evidence a reader can check: named awards, credentials, case studies published with permissionA claim nobody can verify does not help a buyer decide, and gives an answer nothing concrete to repeat
Absence from relevant answersThe business is not named for questions it clearly fitsRule out the basics: the site can be crawled and is indexed, and each service has its own clear page. Then look at which sources the answers cite, and whether the business is accurately present in themAbsence has many possible causes; access and clarity are the ones you control directly, so they come before anything that depends on others

None of this guarantees a particular answer. It makes the accurate picture of your business the easiest one to find.

A repeatable assessment you can run

A first assessment takes an afternoon. What makes it useful is running it the same way each time, so that differences reflect the answers rather than the method.

  1. Fix your questions. Write ten to twenty questions in your customers’ words, covering each service and each type of customer you want, and note the intent behind each: comparing options, looking for a provider, or checking a detail. Keep the list unchanged between rounds.
  2. Fix the conditions. Use the tools your customers use, usually ChatGPT, Google (AI Overviews and AI Mode), Gemini, Perplexity and Microsoft Copilot. Start a fresh chat each time, signed out where the tool allows, with the same location setting.
  3. Record each answer on the worksheet below, as it is, before deciding what it means.
  4. Check that your site can be read. Confirm that robots.txt allows the search crawlers (Googlebot, Bingbot, OAI-SearchBot, PerplexityBot and Claude-SearchBot) and that your important pages are indexed, in Google Search Console and Bing Webmaster Tools. Bing’s AI Performance report shows which of your pages Copilot cites.
  5. Repeat. Answers vary between runs, tools and days. Ask each question more than once in a round, repeat the round monthly, and act on patterns that recur rather than on a single answer.
What to recordWhat to write down
Buyer question and intentThe exact wording, and whether the buyer is comparing, looking for a provider, or checking a detail
Platform, date and languageThe tool, signed in or out, the location setting, the date and the language of the question
Mentioned, cited or recommendedNamed in the text; linked as a source; suggested as a choice. Record each separately
Accuracy and relevanceEvery incorrect detail, and whether the description explains why the business fits this buyer
Sources linkedEach cited page, and whether it is yours, a listing, a review site or an article
Suggested next actionThe one change this answer points to, using the order in the table above

Keep the observations as they are rather than turning them into a single score. A number would hide what actually needs changing, and there is no agreed method that makes one comparable between tools or over time.

What the research says

Studies of AI search are young and fast to date, because the tools change. They are still useful for what they show about how answers use sources. The figures below are from the studies themselves; Glowtice has not tested them.

StudyWhat was testedWhat it foundLimits
Aggarwal and colleagues, KDD 2024Nine ways of rewriting a source, across a benchmark of 10,000 queries, in an experimental engine built on GPT 3.5 Turbo, with a smaller test on PerplexityThe best methods, including citing sources, adding quotations and adding statistics, raised a source's visibility in answers by up to 40%; keyword stuffing did not helpAn experimental engine rather than commercial tools, scored partly by a language model; the authors expect methods to change as engines evolve
Liu, Zhang and Liang, EMNLP Findings 2023Human review of answers from Bing Chat, NeevaAI, perplexity.ai and YouChat, 1,450 queries eachOn average, 51.5% of sentences were fully supported by their citations, and 74.5% of citations supported their sentenceEarly 2023 versions of tools that have since changed; it measures whether claims are supported, not whether they are true
Tow Center, Columbia Journalism Review, 2025Eight AI search tools asked to identify the source of 200 news excerpts each, 1,600 queries in February 2025Together the tools answered more than 60% of queries incorrectly; Perplexity 37%, Grok 3 94%News articles only; each excerpt was run once, and the authors say the results should not be extrapolated to all models
Pew Research Center, 2025The Google searches of 900 US adults in March 2025, 68,879 searchesPeople clicked a traditional result on 8% of visits to pages with an AI summary, against 15% without one; Wikipedia, YouTube and Reddit were the most cited sourcesGoogle only, United States only, one month
Nestaas, Debenedetti and Tramèr, 2024Hidden instructions on test web pages, aimed at Bing Copilot, Perplexity and AI pluginsManipulated pages made a product 2.5 times more likely to be recommended in Bing Copilot; when several parties manipulate, all of them lose visibilityPages controlled by the researchers; Bing Copilot's behaviour changed during the study
Kumar and Lakkaraju, 2024An optimised text sequence added to one product page in a catalogue of ten fictitious coffee machines, on an open model (Llama 2)The added text could move a product from not being recommended to the top recommendationOne open model and a fictitious catalogue; not tested on commercial search tools

What this means in practice:

  • Specific, verifiable content is the safe ground. Clear facts, named sources and figures that can be checked are what the experiments rewarded, and they are also what a reader needs.
  • Check what is said, not only whether you are named. Citations are often imperfect, so an answer can attach your name to a wrong detail, or cite a page that does not support it.
  • Being in the answer matters more as clicks fall. If fewer people click through, the description inside the answer carries more of the first impression.
  • Avoid tricks. Manipulation can work in a lab, but it is fragile, platforms work against it, and when several businesses try it, all of them lose.

Common questions

Is GEO the same as AEO or "AI SEO"?

They describe the same goal. Answer engine optimization (AEO), AI search optimization and AI SEO are other names for making a business appear accurately in answers from AI tools. GEO is the term used in the research that named the field.

Do I need special files or markup for AI search?

Google says there are no additional requirements to appear in AI Overviews or AI Mode, and no special structured data or AI text files are needed. Pages need to be indexed and eligible for a snippet in Search, following normal SEO practice.

If I block GPTBot, will I disappear from ChatGPT search?

No. OpenAI uses separate crawlers. OAI-SearchBot decides whether your pages can appear in ChatGPT search answers; GPTBot is for training models. Each is allowed or blocked separately in robots.txt.

Will adding statistics, quotations or citations get my business cited?

Not reliably. In the research that named GEO, those changes raised a source's visibility in an experimental engine, and the authors note that methods may need to change as engines evolve. They are good writing practice, because they make a page more specific and verifiable, not a switch that commercial AI tools respond to.

Can anyone guarantee what an AI tool says about my business?

No. AI tools write each answer themselves, and answers vary between questions, tools and days. GEO improves the information those tools rely on, so the picture they form of you is clear, accurate and easy to find.
