To get cited by ChatGPT, your pages first have to be reachable by OpenAI's search crawler, OAI-SearchBot, and then worth quoting: clear answers, real evidence and pages that are easy to find. No one can guarantee a citation, but you can remove the reasons you would be skipped.
Key takeaways
- ChatGPT's search features use OAI-SearchBot to surface websites. Sites that opt out of OAI-SearchBot will not be shown in ChatGPT search answers, though they can still appear as navigational links.
- OAI-SearchBot and GPTBot are separate settings. You can allow search while disallowing training.
- OpenAI notes it can take about 24 hours after a robots.txt change for its search systems to adjust.
- Content that cites sources, adds quotations and uses statistics was more visible in generative engine answers in published research.
- Citation is never guaranteed, so check your target questions regularly and improve the pages that are not cited.
How does ChatGPT decide which websites to cite?
ChatGPT cites websites through its search features, which find pages using OpenAI's OAI-SearchBot crawler. OpenAI does not publish a ranking formula, but it is clear on the first requirement: if your site blocks OAI-SearchBot, it will not be shown in ChatGPT search answers (OpenAI).
Everything after access is about being a good source. A page that answers the question directly, backs it with evidence and is clearly tied to a real business gives the system something safe to quote.
Is your site allowed to be crawled by OAI-SearchBot?
Check your robots.txt and your host or CDN settings first. OpenAI recommends allowing OAI-SearchBot in robots.txt and allowing requests from its published IP ranges to help your site appear in search results (OpenAI).
| OpenAI user agent | What it is for | What blocking it does |
|---|---|---|
| OAI-SearchBot | Surfacing websites in ChatGPT's search features | Your site will not be shown in ChatGPT search answers, though it can still appear as a navigational link |
| GPTBot | Crawling content that may be used to train OpenAI's generative AI foundation models | Signals your content should not be used for training; it is a separate setting from search |
A common setup is to allow OAI-SearchBot and decide on GPTBot separately. OpenAI says each setting is independent of the other.
How do you get cited by ChatGPT, step by step?
Fix access, then make each important page the clearest answer to one real question.
- Allow OAI-SearchBot. Review robots.txt and any firewall or CDN bot rules. After a change, allow about 24 hours for OpenAI's systems to adjust.
- Pick the questions you want to be cited for. Write them the way a customer would type them into ChatGPT.
- Give one page a clear job. Each page should answer one main question, with related sub-questions as headings.
- Answer in the first lines. Put a one to three sentence answer under each heading that still makes sense if quoted alone.
- Add evidence. Cite reliable sources, quote named experts or your own documented policies, and use real numbers where you have them. In the GEO research, Cite Sources, Quotation Addition and Statistics Addition were the top-performing methods (Aggarwal et al., KDD 2024).
- Make the business behind the page clear. State who you are, what you do and where you work, and keep that consistent across your site.
- Keep it in plain text. Put important content in HTML text, not only inside images or scripts.
- Link related pages. Internal links help crawlers and readers reach your other answers.
- Test and update. Ask your target questions in ChatGPT, note which sources it cites, and improve the pages that are missing.
What kind of content is more likely to be cited?
Content that is specific, sourced and easy to quote. The GEO paper found that adding citations, quotations and statistics improved visibility in generative engine answers, and that Cite Sources was particularly beneficial for factual questions. Keyword stuffing did not perform well (Aggarwal et al.).
| Less likely to be quoted | More likely to be quoted |
|---|---|
| "We offer great service at fair prices." | A clear statement of what is included, with your published terms |
| A long intro before the answer | The answer in the first one to three sentences |
| Claims with no source | Claims linked to official documentation or research |
| The same keyword repeated | Plain language that answers the question |
How long does it take to get cited by ChatGPT?
There is no fixed timeline. OpenAI says robots.txt changes can take about 24 hours to take effect for search, but being crawled is not the same as being cited. Plan to check your target questions over weeks, not days, and keep improving the pages.

Frequently asked questions
How to get cited by ChatGPT?
Allow OpenAI's OAI-SearchBot to crawl your site, then make each important page the clearest answer to one real question: answer in the first lines, cite reliable sources, use real evidence and keep the content in plain text. Citation is not guaranteed, so test and update regularly.
Why is my website not showing up in ChatGPT answers?
A common cause is that OAI-SearchBot is blocked in robots.txt or by a firewall or CDN rule. OpenAI states that sites opted out of OAI-SearchBot will not be shown in ChatGPT search answers. If access is fine, the page may not answer the question clearly enough to be quoted.
Does blocking GPTBot stop ChatGPT from citing my site?
No. GPTBot and OAI-SearchBot are separate settings. OpenAI says you can allow OAI-SearchBot to appear in search results while disallowing GPTBot to signal that your content should not be used for training its foundation models.
How long does it take to get cited by ChatGPT?
There is no fixed timeline. OpenAI says it can take about 24 hours after a robots.txt update for its search systems to adjust, but crawling is not the same as being cited. Check your target questions over several weeks.
Can you pay to get cited by ChatGPT?
OpenAI's crawler documentation describes no paid route to citations. What it does describe is allowing OAI-SearchBot so your site can appear in search results. From there, clear and well-sourced content is what makes a page worth citing.
