How ChatGPT, Gemini and Google's AI answers choose which builder to name
What each company publishes about the way its assistant reads a builder's website, what remains unpublished, and the seven things a builder controls.
See if customers can find youNo company publishes the full rules by which ChatGPT, Gemini, Perplexity or Google's AI answers choose a builder. Each one does publish how its programs read websites. Google says its AI features carry no additional requirements beyond ordinary search practice, and OpenAI says a site that blocks its search program will not be shown in ChatGPT search answers. A builder therefore controls two things: access for those programs, and pages that state plainly who builds what, and where.
What are these AI tools, and where does a builder meet them?
An AI assistant is a program that answers a question in written sentences. ChatGPT is made by OpenAI, Claude by Anthropic, Gemini by Google, and Perplexity by the company of the same name. A person can ask one of them "who builds casitas in Phoenix" and receive a written answer, where a search engine returns a list of links.
Google has placed answers of the same kind inside its search results. It describes two features: AI Overviews, which help people understand the main point of a complicated question quickly and give links to learn more, and AI Mode, for questions that need further exploration, reasoning or comparison, which returns an AI-written response with links to supporting websites. Google adds that an AI Overview is shown only when its systems judge that it adds to the classic results.
A builder therefore meets these tools in two places: as a link in an answer on Google, and as a name inside an assistant's reply. In both, the builder's own website is the part the builder controls.
What does Google say about appearing in its AI answers?
Google's page on AI features says that the best practices for search engine optimization (the work of helping a website appear in search results, shortened to SEO) remain relevant for AI features, and that there are no additional requirements to appear in AI Overviews or AI Mode. To be eligible as a supporting link, a page must be stored in Google's records of the web (Google calls this being indexed) and be eligible to appear in Google Search with a snippet, the few lines of text under a result.
The page then lists the work that continues to be worthwhile: allowing Google's reading program to reach the site, making content easy to find through links between your own pages, keeping important content in text, making sure the business details written for programs match the visible text, and checking that the Business Profile (the listing that shows a business on Google Search and Google Maps) is up to date. Google states that an owner needs no new machine-readable files, no AI text files and no special labels in the page code to appear in these features.
Which programs read a builder's website for each AI company?
Each of these companies sends programs across the web to read pages. The trade calls them crawlers or bots, and every company publishes their names. The table gives each name and what the company says the program does.
OpenAI and Anthropic each separate the program that reads for search answers from the one that collects training material, so an owner can allow the first and decide separately about the second. Google does the same with a setting name: Google-Extended covers the training of Gemini models and the content supplied to Gemini, has no effect on a site's inclusion in Google Search, and plays no part in how Google Search orders its results. For the AI answers inside Google Search, the program that matters is Googlebot.
| Company | Program name | What the company says it does |
|---|---|---|
| OpenAI | OAI-SearchBot | Shows websites in ChatGPT's search features. A site that opts out will not be shown in ChatGPT search answers |
| OpenAI | GPTBot | Reads content that may be used to train OpenAI's AI models |
| OpenAI | ChatGPT-User | Visits a page when a person's question to ChatGPT calls for it |
| Anthropic | ClaudeBot | Collects web content that could contribute to training Anthropic's AI models |
| Anthropic | Claude-SearchBot | Reads the web to improve the quality of search results for Claude users |
| Anthropic | Claude-User | Visits a page when a person asks Claude a question |
| Perplexity | PerplexityBot | Shows and links websites in Perplexity's search results. Perplexity says it collects no content for training AI models |
| Perplexity | Perplexity-User | Visits a page when a person asks Perplexity a question |
| Googlebot | Reads pages for Google Search, including all Google Search features | |
| Google-Extended | A setting name with no program of its own. It controls whether pages Google has read are used to train Gemini models and to supply Gemini with content |
How does a website let these programs in, or keep them out?
A website can carry a small text file named robots.txt, which, as Google describes it, tells the reading programs of search engines which addresses they can access on the site. Each entry names a program and says what it is allowed to open. Anthropic says its programs honor these instructions, and Google says its common reading programs always obey them when they read automatically. A visit requested by a person is treated differently: OpenAI says the rules may not apply to ChatGPT-User, and Perplexity says Perplexity-User "generally ignores robots.txt rules".
What should a builder do with this? A builder who wants to be named should let the search programs in. OpenAI recommends allowing OAI-SearchBot so that a site can appear in ChatGPT's search results. Perplexity makes the same recommendation for PerplexityBot and says a change can take up to 24 hours to be reflected. Anthropic says that disabling Claude-SearchBot may reduce a site's visibility in user search results. Ask whoever maintains your website to show you the file, which is found at your domain followed by /robots.txt.
What are the seven things the Get Found Check looks at for AI readiness?
The Get Found Check gives a separate grade for readiness for AI assistants, and that part looks at exactly seven things. The list is Licheo's own: seven things an owner controls. Here is each one with a builder's example.
- Business details a program can read. These are labels in the page code, written in a shared vocabulary called Schema.org structured data, that state the business name, address and phone number. In our sample of 80 builder websites, one builder's labels gave a hosting server address as the website and email address.
- Question-and-answer content. A casita page that asks "Can I rent out a casita in Arizona?" and answers in the next sentence states the question and the answer together, in the words a buyer uses.
- Who the business is and what it does. The homepage says in its first lines that the company builds custom homes in a named city. On at least 12 of the 80 builder websites we read, the homepage title or main heading named no service or no city.
- Cited sources and figures. A page on Arizona's middle-housing rule that names the statute, section 9-462.13 of the Arizona Revised Statutes, and its deadline of January 1, 2026 can be checked by any reader.
- Direct answers to specific questions. The answer comes in the first sentence under the heading, and the explanation follows it.
- Depth. Several pages cover related topics and link to each other: the casita page links to the article on permits, to the finished projects and to the city page.
- Access for the reading programs. The Check looks at whether the site lets in GPTBot, ClaudeBot, PerplexityBot and Google-Extended, four of the names in the table above.
What should a builder put on the site for each of the seven?
The table turns the seven into work. Google's own documentation supports several rows: it says structured data helps Google understand the content of a page and gather information about the companies described in it, and it asks that the labels match the visible text. Its guidance on helpful content asks for clear sourcing and for background about the site that publishes a page. It must be said that Google also states that no special structured data is needed for its AI features: the labels help a program understand a page.
| Signal | What it means for a builder | What to put on the site |
|---|---|---|
| Business details a program can read | A program reads your name, address and phone number from labeled fields | Schema.org labels for the business that match the visible text on the page |
| Questions and answers | A buyer's question appears on your page in the buyer's own words | The questions clients ask on the phone, each followed by its answer in full sentences |
| Clear identity | A reader knows from the first lines who builds what, and where | A homepage title and main heading with the service, the city and the business name |
| Cited sources and figures | Your statements about laws and sizes can be checked | The statute or ordinance number, and its date, beside each rule you quote |
| Direct answers | The answer comes before the explanation | A first sentence under each heading that answers the heading |
| Depth | One subject is covered by several linked pages | Service pages, city pages, project pages and articles that link to each other |
| Access for reading programs | The AI companies' programs are allowed to read the site | A robots.txt file that allows the search programs named in the first table |
What does it look like when a builder's site is cited?
VanPlex is a Vancouver multiplex builder and developer site, and one of the properties where Licheo's team tests its methods first. It is cited in Google's AI Overview for "multiplex co-development". It holds the featured snippet (the boxed result in which Google shows the descriptive text first) and the top organic result, meaning the top unpaid one, on Google for "multiplex developer vancouver", and it ranks first for "Multiplex vancouver map". Bing Webmaster Tools, the Bing search engine's service for site owners, showed 311 AI citations and 13 average cited pages in one seven-day period.
The screenshots are on our case studies page, and we have written a case study post about the site. We offer this as one record from one site: it demonstrates that a builder and developer site can be cited in Google's AI Overview.
What stays unknown about how an assistant picks a builder?
The selection rules themselves stay unknown. The four company pages we opened for this guide describe which programs read a website and how an owner allows or blocks them. None of the four lists the rules by which an assistant chooses one business over another.
Google is explicit about the limits. Its page on AI features says that a page meeting all requirements and best practices can still go unread or unshown, because showing a page is never guaranteed, and that AI Mode and AI Overviews can use different models and techniques, so the responses and links they show will vary. Its Starter Guide says there are no secrets that will automatically rank a site first.
What follows for a builder? None of the sources above supports a promise of a fixed place in an AI answer, so put the effort into what the sources do describe: a site the programs can read, pages that say plainly who builds what and where, and statements a reader can check.
Where should a builder start with AI assistants?
Start by measuring the present site. The free Get Found Check reads your homepage, your domain settings and your security certificate, and in under 60 seconds returns a letter grade from A to F, together with a separate grade for readiness for AI assistants. It reads one page, so the grade is a place to start.
Then put to an assistant the question your buyer asks, with your service and your city, and write down which businesses it names. Repeat the question each month and keep the answers. If you prefer that the work is done for you, our service has one flat monthly fee, month to month, with no contract.

Questions people ask
- Can a small home builder appear in Google's AI Overview?
- A small home builder can appear in Google's AI Overview when its page is stored in Google's records and eligible to be shown with a text preview; Google says there are no additional requirements. One record: VanPlex, a Vancouver multiplex builder and developer site where Licheo's team tests its methods first, is cited in Google's AI Overview for "multiplex co-development". Google adds that showing any page is never guaranteed.
- Does a builder need a special file for ChatGPT or Gemini to read the website?
- A builder needs no special file for Google's AI features: Google states that owners need no new machine-readable files, AI text files or special labels in the page code to appear in AI Overviews and AI Mode. The one file that matters for access is robots.txt, which tells reading programs which addresses they can open. OpenAI recommends allowing its search program, OAI-SearchBot, in that file so that a site can appear in ChatGPT's search results.
- What is GPTBot, and should a builder's website allow it?
- GPTBot is the program OpenAI uses to read content that may be used to train its AI models, according to OpenAI's own page. The program that shows websites in ChatGPT's search features has a different name, OAI-SearchBot, and OpenAI says a site that opts out of it will not be shown in ChatGPT search answers. A builder who wants to be named should allow OAI-SearchBot. Allowing GPTBot is a separate choice.
- What does Google-Extended control on a builder's website?
- Google-Extended controls whether pages Google has read from a builder's website are used to train Gemini models and to supply Gemini with content at the moment of a question. Google states that Google-Extended has no effect on a site's inclusion in Google Search and plays no part in how Google Search orders its results. For AI Overviews and AI Mode inside Google Search, Google says the control is the ordinary setting for Googlebot.
- How does ChatGPT decide which home builder to recommend?
- How ChatGPT decides which home builder to recommend is unpublished: OpenAI's page on its reading programs explains access and gives no selection rules. It does state that a site opted out of OAI-SearchBot will not be shown in ChatGPT search answers. A builder therefore controls two things with certainty: access for that program, and pages that say plainly what the business builds and where.
- Do questions and answers on a builder's page help with AI assistants?
- Questions and answers on a builder's page help the reader first, and none of the AI company pages we read publishes a rule about them. They are one of the seven things the AI-readiness part of Licheo's Get Found Check looks at, because a page that states a buyer's question in the buyer's words and answers it in the next sentence leaves nothing to infer. Google says its AI features require no special labels in the page code.
- How can a builder find out whether AI companies' programs can read the website?
- A builder can find out whether AI companies' programs can read the website by opening the robots.txt file, found at the domain followed by /robots.txt, and looking for entries that name the programs. The AI-readiness part of the free Get Found Check looks at the same thing for GPTBot, ClaudeBot, PerplexityBot and Google-Extended. Perplexity says a change to the file can take up to 24 hours to be reflected in its systems.
- Does Perplexity use a builder's website to train AI models?
- Perplexity says that PerplexityBot, the program that shows and links websites in its search results, collects no content for training AI models. Its second program, Perplexity-User, visits a page when a person asks a question, and Perplexity says it collects no training content either. To appear in Perplexity's search results, the company recommends allowing PerplexityBot in the site's robots.txt file, the text file that tells reading programs what they can open.
- What is the difference between ClaudeBot and Claude-SearchBot for a builder's website?
- ClaudeBot and Claude-SearchBot are two programs from Anthropic with separate jobs. Anthropic says ClaudeBot collects web content that could contribute to training its AI models, while Claude-SearchBot reads the web to improve search results for Claude users. Anthropic adds that disabling Claude-SearchBot may reduce a site's visibility in user search results, and that its programs honor the instructions in a site's robots.txt file.
- Can anyone guarantee that an AI assistant will name a builder?
- Nobody can guarantee that an AI assistant will name a builder, because no company publishes complete selection rules. Google's page on AI features says that showing a page is never guaranteed, even for a page that meets all requirements, and its Starter Guide to search engine optimization says there are no secrets that automatically rank a site first. What a builder controls is access for the reading programs and clear pages that a reader can check.
