**ChatGPT search pulls live web results into answers with citations, so brands get found by being crawlable by OAI-SearchBot, by having pages that clearly answer buyer questions, and by being described consistently across trusted sites.** OpenAI doesn't publish how it ranks or chooses citations, so focus on what you control and measure the results.

> **Key takeaways**
>
> - Allow OAI-SearchBot in robots.txt and its IP ranges at your firewall. GPTBot (training) is separate.
> - ChatGPT-User fetches pages when a user asks and may not follow robots.txt rules.
> - Search may rewrite queries, send them to search partners and use approximate location, so results vary.
> - Retailers can share product feeds through OpenAI's merchants programme.
> - There's no guaranteed placement; test buyer questions and track change over time.

## How does ChatGPT search work?

From OpenAI's search help article: search is available on all plans and to logged-out users. ChatGPT decides when to search or you can ask it to. Answers include inline citations and a Sources button. ChatGPT may rewrite your query into one or more searches and send them to search partners, may use memory to shape the rewrite and uses approximate location from your IP address.

That's why two marketers asking the same question can see different brands. See [why ChatGPT search results differ](https://mentionx.ai/learn/engines/chatgpt/search-results-differ).

## Which crawlers matter?

| Crawler | Purpose | Your control |
|---|---|---|
| OAI-SearchBot | Inclusion in ChatGPT search | robots.txt and allowing its IP ranges |
| GPTBot | Training of models | robots.txt, separate from search |
| ChatGPT-User | Fetches a page when a user asks | May not follow robots.txt |
| OAI-AdsBot | Checks ad landing pages | Relevant only if you run ChatGPT Ads |

```
CRAWLER CHECK
Here's our robots.txt [paste] and our CDN's bot rules [paste].
For OAI-SearchBot, GPTBot and ChatGPT-User, say what is
allowed, what is blocked and whether that matches this
policy: [our intent].
```

## What can you influence?

- **Answer-ready pages:** pages that state what you do, for whom, pricing model and how you compare, in plain text near the top.
- **Consistency:** the same facts on your site, review sites, directories and partner pages.
- **Third-party coverage:** reviews, comparisons and articles on sites that ChatGPT search cites in your category.
- **Product data:** retailers can apply to share product feeds through OpenAI's merchants page; OpenAI says shoppers buy on the merchant's site by default.
- **Corrections:** when ChatGPT gets a fact wrong, fix the sources it cites. See [fixing wrong facts about your brand](https://mentionx.ai/learn/engines/chatgpt/fix-wrong-facts-about-brand).

```
CITATION AUDIT
Search: "[buyer question]". List every brand mentioned and
every source cited, with URLs. Which sources mention us, and
what do they say? Which cited sources don't mention us?
```

Run the audit on 10-20 buyer questions. The cited sources that don't mention you are your outreach and content list. For a starting set, use the [buyer prompt library](https://mentionx.ai/learn/engines/chatgpt/buyer-prompt-library-50-prompts-test), and for diagnosis see [why AI engines ignore a brand](https://mentionx.ai/learn/engines/chatgpt/ai-engines-ignore-brand-7-diagnoses). Shopping brands should also read [ChatGPT shopping and product recommendations](https://mentionx.ai/learn/engines/chatgpt/shopping-and-product-recommendations).

*Our view:* treat ChatGPT visibility like PR plus technical SEO. The technical part (crawlers, clear pages) is quick to fix; the reputation part (being cited by sources ChatGPT trusts) takes months.

> **Pro move:** run the citation audit logged out and in a temporary chat as well as in your normal account. Memory and location shape the query rewrite, so your own account isn't a neutral view.

## Worked example: Ledgerline's citation audit

*Ledgerline is a fictional accounts-payable tool. Details are illustrative.*

Ledgerline's robots.txt allowed GPTBot but its CDN blocked unknown bots, including OAI-SearchBot. Fixing the CDN rule was step one. The citation audit across 15 buyer questions found Competitors A and B cited from two comparison sites where Ledgerline had no listing, and Ledgerline's own pricing page cited with an old tier name. The team updated the page, applied for listings and planned to rerun the audit monthly.

## What should you check before the next lesson?

- Run the crawler check on your robots.txt and CDN rules.
- Audit 10 buyer questions and list cited sources that don't mention you.
- Fix one wrong fact at its source.
- Compare with [how Claude chooses sources](https://mentionx.ai/learn/claude/how-claude-chooses-sources-get-cited).

## Common questions

**How do I get my site into ChatGPT search?** Allow OAI-SearchBot in robots.txt and its published IP ranges in your firewall. OpenAI says sites that opt out of OAI-SearchBot will not be shown in search answers, though they may still appear as navigational links.

**Does blocking GPTBot remove me from ChatGPT search?** No. GPTBot relates to training. OAI-SearchBot controls inclusion in ChatGPT search, and the two are set separately.

**Can I pay to be recommended in ChatGPT answers?** No. OpenAI says ads do not influence answers. Ads appear separately and are labelled.
