ChatGPT can automatically search the web when a question would benefit from current information, or the user can enable Search deliberately. Websearch responses can show inline citations or a Sources panel of used and related sources. The source probability therefore does not depend on one GEO trick, but on crawlability, source quality, clear entities, evidence, relevance and a strong SEO basis.

How does ChatGPT Search work?
ChatGPT Search combines a conversation with current web information and can provide answers with citations and links to sources.
ChatGPT can rewrite a question into one or more targeted searches and also use external search providers for this. The answer may show inline citations. If these are not visible, the user can access the cited and other relevant links via Sources.
| Part | What this means |
|---|---|
| Automatic search | ChatGPT can decide for itself that current or web-based information is useful. |
| Manual search | The user can choose Search or have an answer generated again with web search. |
| Inline citations | Source references can be placed directly next to statements in the answer. |
| Sources panel | A separate overview can show cited sources and other relevant links. |
| No search | Not every answer uses web search or cites a current web source. |
This operation is described in the official explanation of ChatGPT Search.
Can any website appear in ChatGPT Search?
Any public website may appear in ChatGPT Search, but public availability does not guarantee inclusion, citation, or prominent placement.
OpenAI indicates that ranking uses multiple factors to show reliable and relevant information. There is no way to guarantee a top position. To be included in summaries and snippets, OAI-SearchBot must be able to crawl the relevant pages and the hosting, firewall or CDN must allow traffic from the published OpenAI IP ranges.
Which crawler is important for ChatGPT Search?
OAI-SearchBot is the crawler that OpenAI uses to show websites in ChatGPT Search results.
The crawler settings are independent. You can allow OAI-SearchBot to make content available for ChatGPT Search and block GPTBot if you do not want content to be used for potential model training.
| Crawler | Function |
|---|---|
| OAI SearchBot | Automatic search crawler for websites that can be shown in ChatGPT Search answers. |
| GPTBot | Crawler for content that might be used to make generative foundation models more useful and secure. |
| ChatGPT User | User agent for certain actions that a user initiates in ChatGPT or a Custom GPT; not the automatic search crawler. |
| OAI AdsBot | Crawler for security checking of submitted ad landing pages; not for organic source selection. |
Always check the current official documentation about OpenAI crawlers, as user agent versions and IP ranges may change.
How to configure robots.txt for search without training?
Allow OAI-SearchBot and block GPTBot if you want to appear in ChatGPT Search but don't want the content to be used for potential foundation model training.
User-agent: OAI-SearchBot
Allow: /
User-agent: GPTBot
Disallow: /In addition, check whether CDN, firewall, hosting or bot protection rejects requests from the official IP ranges. OpenAI mentions that it can take approximately 24 hours for systems to adapt to a change in robots.txt.
What happens when OAI-SearchBot is blocked?
When OAI-SearchBot is blocked, the page is not used for content summaries and snippets in ChatGPT Search.
OpenAI can discover a URL through a third-party search provider or other page and show only the link and page title in certain situations. Anyone who doesn't want that either uses a noindex meta tag. The crawler must be allowed to retrieve the page to read the noindex statement.
Should you allow GPTBot to be quoted?
No. GPTBot and OAI-SearchBot have different features, and allowing GPTBot is not a requirement to appear in ChatGPT Search.
Block or allow GPTBot based on your choice about possible model training. Manage organic ChatGPT Search visibility via OAI-SearchBot.
Does your website need to be indexed in Google?
A Google index is not an official requirement for ChatGPT Search. The page must be public, relevant and accessible to OAI-SearchBot.
Good Google indexing remains practically valuable because the same technical SEO basics helps: consistent canonicals, internal links, sitemaps, clear HTML content and reliable source pages. However, Google indexing by itself does not guarantee ChatGPT citation.
Which pages are most likely to serve as a source?
Source-worthy pages answer one clear question, contain verifiable information and make it visible who is responsible for the content.
| Source attribute | Why it helps |
|---|---|
| Instant answer | The core question is answered early and without a long detour. |
| Specific facts | Definitions, numbers, conditions, locations and limitations are in visible text. |
| Primary information | The page contains your own expertise, data, product information or a transparent methodology. |
| Authorship | A recognizable person or organization is responsible for the content. |
| Current affairs | Publication or update date and changeable facts are maintained. |
| Sources and evidence | Claims are linked to reliable sources, cases or public documentation. |
| Clear structure | Headings, tables, lists and internal links make the content understandable. |
| Unique source function | The page has a standalone query and does not duplicate any other URL. |
How do you write quotable passages?
A quotable passage provides a complete and accurate answer that remains understandable beyond the rest of the page.
- Start a main section with one sentence that directly answers the heading.
- State the subject and the most important relationship explicitly, without unclear references.
- Add necessary context, limitation, and date close to the claim.
- Use a table when comparison or selection is central.
- Don't just put important facts in images, videos, downloads or interactive widgets.
- Vermijd claims zoals beste, uniek of gegarandeerd zonder controleerbaar bewijs.
- Link to the primary source or case on which the statement is based.
How do you build a source architecture for ChatGPT?
A source architecture links every important question or entity to one primary page and connects it to evidence, author and in-depth sources.
| Source layer | Function |
|---|---|
| Primary answer page | Best own page for the specific question or service. |
| Organization page | Official source for company name, location, offering, founder and contact. |
| Person page | Official source for role, expertise, authorship and professional profiles. |
| Service page | Problem, target group, activities, deliverables, work area and limitations. |
| Case page | Role, period, data source, result and context. |
| Methodology or source page | Explains data, calculations, selection criteria or method. |
| External source | Reliable third party confirming important facts or expertise. |
The central company resource is About Jakency and the authorship is associated with Jan Kenis. A case such as Ask Gustavo shows how measurement results are treated per channel as a separate layer of evidence.
How important are entities and consistency?
Consistent entities help systems understand that the same organization, person, service or location is referred to across different pages and resources.
Use the same official names, roles, locations, contact details and service definitions on your website and relevant external profiles. Connect Organization, Person, Service, Place and cases with clear internal links and where appropriate structured data and schema.org.
Is llms.txt needed for ChatGPT?
OpenAI does not list llms.txt as a requirement to appear in ChatGPT Search.
The current publisher guidelines focus on public content, OAI SearchBot access and reliable, relevant pages. A llms.txt file can be tested as additional documentation, but is not an official OpenAI requirement and does not replace robots.txt, indexable HTML, or strong source pages.
How important is accessibility?
Accessible HTML and clear semantics help people, search engines, and agents understand the page and interactive components.
OpenAI recommends descriptive ARIA roles, labels and states for buttons, menus and forms for ChatGPT Agent in Atlas. This is accessibility and agent compatibility advice, not a proven ranking factor for ChatGPT Search.
Can you pay to appear organically in ChatGPT answers?
You cannot purchase organic source selection, citations, or recommendations in ChatGPT answers.
ChatGPT may separately display sponsored advertisements. OpenAI says ads are clearly labeled as sponsored, are visually separate from the organic response, and do not influence the response. An advertisement is therefore not an organic recommendation and does not automatically improve your source position.

How do you measure visibility in ChatGPT?
Measure ChatGPT visibility with a fixed set of questions and register the brand mention, recommendation, own citations, external sources, factual correctness and message per answer.
| Measuring field | What is recorded |
|---|---|
| Prompt and category | Exact question and customer phase. |
| Search mode | Whether web search was active and which visible mode was used. |
| Branding | Does the brand or person appear? |
| Recommendation | Is the brand presented as a suitable choice? |
| Own citation | Is a URL from your own website visibly quoted? |
| Other sources | Which external sites support the answer? |
| Factual correctness | Are key facts correct, complete and up to date? |
| Message | How is the brand or service positioned? |
| Date and context | Time, language, location and relevant account or model context. |
The full methodology can be found at Measuring AI visibility. A GEO audit first establishes the baseline; a GEO strategy then determines how ChatGPT will be addressed within a broader channel plan.
How do you measure traffic from ChatGPT?
Referral traffic from ChatGPT Search can be tracked in analytics via links with utm_source=chatgpt.com.
OpenAI mentions that ChatGPT automatically adds this UTM parameter to referral links. In analytics, create a separate channel group or report view and track landing page, engagement and conversion in addition to sessions.
- AI referral traffic only shows click-throughs, not all non-click brand mentions.
- Some visits may be classified differently or incompletely.
- An increase in referrals does not automatically prove that one GEO change was the cause.
- Combine referral data with prompt measurements, citations and an action log.
Why can two users get different answers?
ChatGPT Search may differ due to question formulation, conversation context, current events, location, memories, search providers and available resources.
| Variable | Possible effect |
|---|---|
| Prompt wording | Other words can trigger other searches and resources. |
| Conversational context | Previous questions can influence the interpretation and search. |
| Location | Global or shared location can change local results and search queries. |
| Memory | When enabled, relevant memory can influence the rewritten query. |
| Current affairs | New pages, facts and changed sources change the available web image. |
| System and provider | Search can rewrite queries and use external search providers. |
How quickly does a custom page appear?
OpenAI does not provide a set time frame within which a new or modified page will be included, cited, or prominently displayed.
A robot change can take about 24 hours for systems to adapt, according to crawler documentation. After that, relevance, reliability, source quality, competition and the specific query remain decisive. Promises that are visible within a few weeks are therefore not substantiated.
Which optimizations usually take priority?
The first actions follow from crawlability, source function, commercial relevance and available evidence strength.
| Signal | First action |
|---|---|
| OAI SearchBot blocked | Correct crawler configuration and firewall or CDN access. |
| Strong page without a direct answer | Improve opening paragraphs, definitions and decision rules. |
| Incorrect brand facts | Make organization, person and external profiles consistent. |
| Own site is not cited | Strengthen primary source page, evidence and internal source architecture. |
| Competitors dominate recommendations | Analyzing demand fit, discriminating evidence and relevant external signals. |
| Outdated citations | Update and republish source page and external facts. |
| No measurement baseline | Run GEO audit and fixed ChatGPT prompt set. |
What common mistakes limit ChatGPT visibility?
- Block OAI-SearchBot while GPTBot is allowed.
- Suggest GPTBot as the crawler needed for ChatGPT Search citations.
- Post important facts only in images, videos or client-side widgets.
- Have multiple pages give the same answer without a clear primary source.
- Add structured data that does not match the visible text.
- Make brand, personal and service information different on external profiles.
- Only test branded prompts and derive broad visibility from them.
- Present a loose quotation as structural growth.
- Confusing paid advertising with organic source selection.
- Promising a fixed publication period or top position.

View all activities at the GEO services or build up knowledge internally via the GEO training.
What is not automatically included?
A ChatGPT optimization process states in advance which audit, content, technology, external profiles and monitoring are included in the scope.
- Guarantee that ChatGPT mentions, recommends or cites the brand.
- Complete rewrite of all website pages.
- Modification of external platforms without access or permission.
- Paid advertising, media budget or advertising management.
- Training opt-in, model training or control over external foundation models.
- Legal assessment of privacy, copyright or regulatory claims.
- Complete causal attribution of leads or revenue without reliable data.
What does optimization for ChatGPT cost?
The price depends on the number of questions, source pages, entities, technical problems, external profiles and desired measurement frequency.
| Price factor | Why it counts |
|---|---|
| Prompt and market reach | More questions, languages and locations require more analysis. |
| Number of entities | Multiple brands, people, services and locations increase the scope. |
| Technical access | Robots, CDN, templates and server-rendered content may require development. |
| Content work | Number of pages and extent of rewrite, facts and evidence. |
| External signals | Profiles, directories and source consistency outside your own website. |
| Measurement | One-off baseline measurement, monthly or quarterly follow-up. |
| Training or guidance | Internal knowledge building and implementation review. |
A concrete proposal will follow after defining the scope. A fixed package price without knowledge of the question set, source pages and technical situation would not be very reliable.
When is ChatGPT optimization not the right first step?
ChatGPT optimization is of little use if the website, positioning or evidence base is not yet sufficiently stable.
- Important pages are not public, crawlable or indexable.
- The organization cannot yet clearly describe services, target group or key facts.
- There are no primary source pages, authors, or cases available.
- The goal is only a guaranteed recommendation or a positive screenshot.
- There is no capacity to implement content or technical recommendations.
- A general SEO audit, GEO audit or reputation restoration takes priority first.
What official sources support this page?
Technical statements about ChatGPT Search, crawlers, referrals and advertisements are based on current OpenAI documentation. The content and GEO recommendations are best practice advice from Jakency and are not presented as an official OpenAI ranking factor.
