How to Get Your Website Recommended by ChatGPT

To get your website recommended by ChatGPT, allow its search crawler in robots.txt, publish pages that answer specific questions in their first paragraph with sources, be present on the lists and review sites it reads when someone asks what to use, and then ask it yourself and look at the sources it shows. There is no form to fill in and nothing to pay.

Most advice on this topic skips the first step and guesses at the rest. This post is built on OpenAI's own crawler documentation and on the research into what generative engines cite, with the guesswork marked as guesswork.

How does ChatGPT find websites to recommend?

ChatGPT search finds websites through OpenAI's search crawler, OAI-SearchBot, and shows only sites that crawler is allowed to read. OpenAI's documentation states that sites opted out of OAI-SearchBot will not be shown in ChatGPT search answers, and recommends allowing it in robots.txt.

The same page separates three OpenAI user agents, and the distinction matters:

  • OAI-SearchBot is for search. It decides whether your site can appear in ChatGPT search answers.
  • GPTBot collects content for training generative models. OpenAI says disallowing it "indicates a site's content should not be used in training," and that each setting is independent of the others.
  • ChatGPT-User fetches a page when a user asks ChatGPT to, so robots.txt rules may not apply, and it "is not used to determine whether content may appear in Search."

So a site can block training and still be recommended, and a site that blocked "all OpenAI bots" in 2023 may have shut itself out of ChatGPT search without noticing. OpenAI adds that a robots.txt change takes about 24 hours to be reflected.

Which robots.txt lines decide whether you can appear?

The group for OAI-SearchBot decides. Open yoursite.com/robots.txt and look for it. If you find User-agent: OAI-SearchBot followed by Disallow: /, you are out of ChatGPT search. If there is a User-agent: * group with Disallow: /, everyone is out. If neither appears, or the file does not exist, you are in.

To allow search and decline training, the two groups look like this:

User-agent: OAI-SearchBot
Allow: /

User-agent: GPTBot
Disallow: /

Our post on checking whether robots.txt blocks AI crawlers covers the other companies' crawlers and the accidental blocks we see most.

What kind of page does ChatGPT quote?

ChatGPT quotes pages it can lift a complete answer from: a first paragraph that answers the question in plain words, sections that each stand on their own, facts with linked sources, and a named author. It is the same shape that earns Google's snippets.

The best evidence for the shape is the 2023 research that defined generative engine optimization. Aggarwal and colleagues at Princeton and Georgia Tech found that adding citations, quotations and statistics to a page raised its visibility in generative engine answers by 30 to 40 percent, while keyword stuffing made pages perform about 10 percent worse. For a business page, that means a sentence like "we have installed 400 of these since 2021" with a photo beats a paragraph that repeats the product name.

Google's advice points the same way, and ChatGPT draws on the open web like every other engine. In a 2025 post on succeeding in AI search, John Mueller of Google wrote "Focus on your visitors and provide them with unique, satisfying content," says John Mueller, Search Advocate at Google, adding that meeting the normal technical requirements "covers you for search generally, including AI formats." Our guide to writing a blog post that gets quoted by AI goes through the shape section by section.

Why do other sites' lists and reviews matter?

ChatGPT recommendations come from pages that already made a judgement: a recommendation is a judgement, and the assistant borrows it from comparison pages, lists, reviews and threads. Ask it "what is the best time tracking app for freelancers" and read the sources it shows: they are usually comparison articles, "best of" lists, review sites and community threads, not the vendors' own pages. A business that appears on none of them has given the assistant nothing to recommend.

That is an observation you can repeat in a minute, not a published statistic, and it leads to three practical moves:

  1. Get listed where your customers compare. Directories for your industry, review sites your customers use, and the comparison articles in your niche that take submissions or quotes.
  2. Answer real questions in the communities the assistant reads. Forum and Q&A threads show up as sources often; a helpful, signed answer there is a mention in the place it counts.
  3. Describe the business the same way everywhere. Name, what you do, where you work. Assistants connect mentions across sites by those details.

PARCHMNT is a writing tool that researches what ranks for a search, writes the page, checks every claim and tracks where it lands in Google and AI answers. Its Get mentioned plan exists for this step: a researched list of the directories, communities, review sites and publications where a particular business should be present, with one specific action per assistant. In our experience building that plan, the places that matter are the same across assistants: the directories, review sites, threads and comparison pages a customer would read before buying.

How do you check whether ChatGPT recommends you?

Ask it the questions your customers ask, in two or three wordings, with search turned on, and read the ChatGPT sources panel under the answer. Getting found by ChatGPT is something you can measure in ten minutes a month. Note three things separately: whether your site is cited as a source, whether your business is named in the answer, and whether it is recommended (suggested, listed or put in bold) rather than mentioned in passing.

Do it monthly, because the answers change as the web changes. Keep the wordings the same each month so you can see movement. If you are not there, the sources that are there tell you exactly what to study: which pages they are, what they contain that yours does not, and where they are mentioned.

Being cited means your page is one of the sources the answer was built from; being recommended means the answer tells the person to use you. Citation comes from the page: it answered the question well enough to be lifted. Recommendation comes from the web around the page: lists, reviews, comparisons and threads that already recommend you, which the assistant repeats.

Most businesses need both and work on only the first. A page can be cited for "how to track billable hours" without the business ever being named; a business can be recommended for "best time tracking app for freelancers" because a comparison article said so, with no page of its own involved. Write the pages that earn citations, and get mentioned on the pages that earn recommendations.

Key takeaways

  • OAI-SearchBot decides whether your site can appear in ChatGPT search; GPTBot only controls training, and the two are independent.
  • A page gets quoted when it answers in its first paragraph, cites sources and stands on its own; citations, quotations and statistics raised visibility 30 to 40 percent in the research that defined the field.
  • Recommendations come from comparison pages, lists, reviews and threads on other sites; be present on them.
  • Ask ChatGPT your customers' questions monthly and read the sources it shows.

Frequently asked questions

No. OpenAI says GPTBot controls training and OAI-SearchBot controls search, and that the settings are independent. Block GPTBot if you prefer not to contribute to training; keep OAI-SearchBot allowed if you want to be found.

Does ChatGPT read structured data?

OpenAI does not document any use of schema markup in its crawler pages, so there is no evidence it is required. Keep structured data for Google, where it supports rich results and makes the author and date explicit, and do not expect it to move ChatGPT on its own.

Not through OpenAI's documented crawlers or search. The route is the same as for Google: pages that answer, and mentions on sites the assistant already trusts. Anyone selling guaranteed placement in ChatGPT answers is selling something they do not control.

How long does it take to appear in ChatGPT answers?

OpenAI gives no figure for appearing, only that a robots.txt change takes about 24 hours to be reflected. In practice the page has to be indexed and ranking before it is cited, so expect weeks, and expect recommendations to follow mentions on other sites rather than your own page alone.

Check the robots.txt line, write the page that answers, get mentioned where the assistant looks, then ask it. If you would rather have the research, the writing, the checks and the monthly asking done for you, try one article free.
