Quick answer
No AI platform publishes a formula for which brands it names. In practice five things shape it: what the model learned in training, what retrieval finds, how clearly your pages state facts, how consistent those facts are across sources, and how the question is worded.
Key takeaways
- Answers combine what a model learned with, when search is on, what it retrieves.
- Clarity and consistency of facts are within your control and affect both.
- Wording, language and location of the question change the outcome.
1. What the model learned
Without search, an assistant answers from training knowledge, a snapshot in time. Brands with a large, consistent public footprint are more likely to be known. Newer or smaller brands may not appear at all.
2. What retrieval finds
When web search is used, the system retrieves pages and writes from them. Being retrievable, and having a page that directly answers the question, decides whether you are drawn in.
3. How clearly a page states facts
Plain, specific sentences are easier to quote than vague marketing language. A page that says what you do, who it is for and what makes it different in a few clear lines gives systems something to use.
4. How consistent facts are across sources
Conflicting names, plans or prices reduce confidence and can cause outdated details to be repeated. Consistency across your site, profiles and third party pages matters.
5. How the question is asked
Wording, language, location and any personal context change which brands appear. That is why a fixed set of prompts, run repeatedly, is more reliable than a single check.
What this is not
What the platforms document, and what they do not
Platforms publish how their crawlers behave, and very little about how an answer is composed. That difference is important. Crawler documentation tells you what you can control at the door: who is allowed to read your pages and for what purpose. It does not tell you why one brand was named over another in a particular answer, and anyone who claims to know the formula is guessing.
| Platform | Documented crawler behaviour | What it does not tell you |
|---|---|---|
| OpenAI | OAI-SearchBot surfaces sites in ChatGPT's search features; GPTBot collects content that may be used in training; ChatGPT-User acts for certain user actions | How a particular answer chooses brands |
| Perplexity | PerplexityBot surfaces and links sites in Perplexity results and is not used to crawl content for foundation models | How sources are ranked within an answer |
| Pages must be indexed and eligible to show with a snippet to be a supporting link in AI features | How supporting links are selected | |
| Anthropic | ClaudeBot collects content that may contribute to training; Claude-User and Claude-SearchBot serve user requests and search quality | How Claude composes a brand recommendation |
The control you do have: separate settings for separate purposes
OpenAI's documentation states that each setting is independent of the others, and gives the example that a webmaster can allow OAI-SearchBot in order to appear in search results while disallowing GPTBot. That matters because a common instinct is to block all AI crawlers at once. Doing so can remove a site from search-connected answers while doing nothing to shape how brands are named from a model's existing knowledge.
It also shows a boundary. A crawler setting decides whether a page can be read. It does not decide whether the page is chosen. Being readable is necessary, and it is the part you fully control.
What separates a brand that is named from one that is not
Across platforms, brands that are named consistently tend to share a few properties that you can inspect. Their facts are stated plainly and match across their own pages and independent sources. They are described on pages that answer the specific question being asked, not only on a homepage. They have a footprint beyond their own site, in reviews, documentation and comparisons. And their names are unambiguous, so a system can tell them apart from a similarly named company.
- Readable: the relevant crawlers are allowed and the important facts are in text.
- Clear: one plain sentence says what the brand is, who it serves and what it does.
- Consistent: the same facts appear on the site, in profiles and in third-party coverage.
- Corroborated: independent sources describe the brand in their own words.
- Specific: there is a page for each question a buyer actually asks.
Treat these as observed factors, not a formula
How to test which factor is holding you back
- 1Run a fixed prompt set on each platform and record whether you are named and how you are described.
- 2For prompts where you are absent, read the sources that were cited and check whether they mention you.
- 3For prompts where you are named poorly, compare the description with your own plain statement of what you do.
- 4Fix the most common cause first, then repeat the same run and compare.
Can I pay to be named in AI answers?
There is no public way to buy a recommendation in an ordinary answer. Some platforms show ads separately, which is a different matter.
Why do two people get different brands?
Location, language, connected accounts and prompt wording can all change the answer.
If I block GPTBot, will I disappear from ChatGPT answers?
According to OpenAI's documentation, GPTBot relates to content that may be used in training, and OAI-SearchBot is separate and relates to search features. Blocking one does not automatically block the other, but you should confirm the current behaviour in OpenAI's documentation before changing your robots.txt.
Does allowing a crawler guarantee a mention?
No. Allowing a crawler makes a page readable. Whether it is chosen depends on relevance, clarity, corroboration and the question asked.
