More buyers now ask ChatGPT the questions they used to type into Google: “best CRM for a small agency”, “is this supplement safe”, “which accountant in Leeds handles crypto tax”. When ChatGPT searches the web to answer, it cites sources and often names specific brands. If yours isn't one of them, you're missing from a growing part of the research journey.
There's plenty of speculation about “ranking in ChatGPT”, so this guide starts with what OpenAI has actually documented: how ChatGPT search works, which crawler controls inclusion, and how to measure the traffic. Then it covers the practical work that makes your brand more likely to be retrieved, cited and recommended.
You'll come away with a technical checklist, a content and reputation plan, and a way to track progress in 2026.
Key Takeaways
- Any public website can appear in ChatGPT search, but only if OpenAI's OAI-SearchBot is allowed to crawl it.
- OAI-SearchBot (search) and GPTBot (model training) are controlled separately in robots.txt.
- ChatGPT rewrites questions into one or more searches, so you need content that answers the specific sub-questions buyers ask.
- Brand mentions on trusted third-party sites, reviews and communities shape how AI assistants describe you.
- ChatGPT adds
utm_source=chatgpt.comto referral links, so you can track visits in analytics.
How ChatGPT search works
ChatGPT doesn't search for every prompt. According to OpenAI's ChatGPT search help article, it may search automatically when a question would benefit from current information, or users can trigger search manually. Some searches go to third-party search providers, and ChatGPT reformulates the question first:
“ChatGPT search typically rewrites your query into one or more targeted queries that it sends those providers.”
— OpenAI Help Center, ChatGPT search
That detail matters. A user asking “what's the best project management tool for a 10-person design agency on a budget?” may trigger searches on comparisons, pricing and use cases. Pages that clearly answer those narrower questions have a better chance of being retrieved and cited.
When ChatGPT doesn't search, it answers from its training data, which updates far less often. Building a consistent reputation across the web helps in both cases.
OpenAI's crawlers: what to allow
| User agent | Purpose | Recommendation for most brands |
|---|---|---|
| OAI-SearchBot | Crawls sites to surface them in ChatGPT search answers | Allow, if you want to appear in ChatGPT search |
| GPTBot | Crawls content that may be used to train OpenAI's models | Your choice; blocking it doesn't remove you from search |
| ChatGPT-User | Fetches pages when a user's request requires it | Allow; it isn't an automatic crawler, and robots.txt may not apply |
“Sites that are opted out of OAI-SearchBot will not be shown in ChatGPT search answers”
— OpenAI, Overview of OpenAI crawlers
The two main crawlers are independent, so you can stay in search while opting out of training:
User-agent: OAI-SearchBot
Allow: /
User-agent: GPTBot
Disallow: /OpenAI says robots.txt changes for search can take about 24 hours to take effect, and recommends also allowing its published IP ranges if your firewall or CDN blocks bots. Check that services like Cloudflare aren't blocking OAI-SearchBot by default. For a refresher on crawl directives, see robots.txt vs meta robots. You may also have seen llms.txt discussed; OpenAI's crawler documentation doesn't mention it, so treat it as optional.
How to get your brand mentioned in ChatGPT: step by step
- Confirm access. Allow OAI-SearchBot in robots.txt, check firewall and CDN bot settings, and make sure key pages return a 200 status with content in the HTML (not only after JavaScript runs).
- Be well indexed in traditional search. ChatGPT uses search providers to find pages, so solid SEO fundamentals remain the foundation.
- Map the questions buyers ask. List the comparison, “best for”, pricing, problem and alternative questions in your category.
- Publish pages that answer them directly. Put a clear answer near the top, then supporting detail, tables and specifics.
- Make facts easy to extract. State prices, features, locations, specifications and who the product is for in plain text, with consistent naming.
- Earn third-party mentions. Get included in credible reviews, comparisons, industry lists, podcasts and news coverage through digital PR.
- Strengthen reviews and community presence. Genuine reviews and helpful participation in forums shape how your brand is described. See our guide to review management.
- Keep everything current. Update pricing pages, product details and key guides; outdated facts get repeated.
- Measure and repeat. Track referrals and test prompts monthly.
Content that ChatGPT is more likely to cite
- Original information: your own data, pricing, case results or expert explanation that other pages don't have.
- Clear structure: descriptive headings, short paragraphs, lists and tables that answer one question each.
- Specificity: “for teams of 5–20” beats “for businesses of all sizes”.
- Honest comparisons: pages that compare you fairly with alternatives, including where others fit better.
- Clear authorship and entity information: who you are, where you operate and what you do, consistent across your site and profiles. Structured data helps machines read this.
These principles overlap heavily with generative engine optimization and AI Overviews optimisation, and with getting cited by Perplexity. One body of good work supports all of them.
Ecommerce: ChatGPT shopping results
For product queries, ChatGPT can show product results. OpenAI's shopping help article says products are chosen by relevance to the user's intent, using structured metadata from providers, and are separate from any ads:
“Product results are selected independently by ChatGPT and are not ads, nor influenced by any OpenAI partnerships.”
— OpenAI Help Center, Shopping with ChatGPT search
The same article says Shopify merchants are connected through Shopify Catalog, while other merchants can apply to send a product feed directly to OpenAI.
How to track ChatGPT visibility
| What to track | How |
|---|---|
| Referral visits | GA4: filter session source for chatgpt.com (ChatGPT adds utm_source=chatgpt.com) |
| Conversions from ChatGPT | GA4 conversions segmented by that source |
| Brand mentions and citations | A fixed set of prompts tested monthly, or an AI visibility tool |
| How you're described | Record the wording, accuracy and competitors named in answers |
| Crawler access | Server logs for OAI-SearchBot requests |
“ChatGPT automatically includes the UTM parameter utm_source=chatgpt.com in referral URLs”
— OpenAI Help Center, Publishers and developers FAQ
Our guides to tracking ChatGPT and AI traffic in GA4 and tracking brand visibility in AI search show the setup in detail. AI answers vary between runs, so look at trends across many prompts rather than single results.
Common mistakes
- Blocking OAI-SearchBot by accident, often through a blanket AI-bot block in a CDN or plugin.
- Confusing GPTBot with OAI-SearchBot. Blocking training doesn't block search, and vice versa.
- Only talking about yourself. AI answers draw on what others say about you, so third-party mentions matter.
- Vague, generic content that doesn't answer the specific sub-questions behind a prompt.
- Inconsistent facts across your site, profiles and directories.
- Chasing tricks. There is no documented way to pay for or request inclusion in organic ChatGPT answers.

Frequently Asked Questions
How do I get my website into ChatGPT search?
Make sure OAI-SearchBot is allowed in robots.txt and not blocked by your firewall or CDN. OpenAI says any public website can appear in ChatGPT search.
Does blocking GPTBot remove my site from ChatGPT search?
No. GPTBot controls whether content may be used for model training; OAI-SearchBot controls search inclusion. They are set independently.
Can I pay to appear in ChatGPT answers?
There is no documented way to pay for inclusion in organic ChatGPT answers. OpenAI says product results are not ads and are not influenced by partnerships.
How can I see traffic from ChatGPT?
ChatGPT adds utm_source=chatgpt.com to referral links, so you can see these sessions in GA4 and other analytics tools.
Is ChatGPT optimisation different from SEO?
It builds on SEO. Being crawlable, indexed and authoritative still matters, but third-party mentions and clearly extractable answers carry extra weight.
Conclusion
Getting mentioned in ChatGPT search starts with simple technical access, then depends on the same things that build trust anywhere: specific, original answers, consistent facts and a strong reputation on other sites. Allow OAI-SearchBot, answer the questions your buyers ask, earn credible mentions and track the results.
