How to Rank in ChatGPT: A Plain Guide for Service Businesses

You can't rank in ChatGPT the way you rank on Google. ChatGPT writes an answer, the answer changes with each question, and nobody can promise you a spot in it. What you can do is make your business easy to find and easy to quote: let OpenAI's search crawler read your site, put clear answers on your pages, and be named the same way on trusted sites. Then check who ChatGPT names, every month.

This guide is for owners of service businesses, not marketing agencies. It separates the one thing OpenAI actually documents from the guesswork in most guides, gives you an afternoon checklist, and shows a free way to check whether ChatGPT names you.

Can you rank in ChatGPT?

Not in the old sense. Google shows a list of ten links, and you can be number three on it. ChatGPT gives one written answer. Sometimes it names businesses, sometimes it links to its sources, sometimes it does neither.

Two people asking almost the same question can get different answers. The same person asking again next week can get a different answer too. So "ranking" in ChatGPT really means two things:

• Being named: your business appears in the answer, for example as one of three plumbers it suggests.
• Being cited: your page is one of the sources the answer links to.

Both are worth having. Neither is a fixed position you can hold. Anyone who sells you "position one in ChatGPT" is selling something that does not exist.

We measure this for our own business. In October 2026 we asked 40 questions our customers might ask, in ChatGPT, Perplexity and Google's AI Mode, and got 117 answers back. Profit AI LAB was named in none of them and our site was cited in 2. In our second check two weeks later it was cited in none. When a question named us directly, all three engines knew who we were. That gap, known by name but not suggested, is where most small businesses sit, and it is why we wrote this guide.

What OpenAI says about appearing in ChatGPT search

Most advice about ChatGPT is educated guessing. One part is not: OpenAI publishes how its crawlers work (OpenAI, Overview of OpenAI Crawlers). A crawler is a program that visits web pages and reads them.

What OpenAI says, in plain words:

• OAI-SearchBot is the crawler for search. OpenAI uses it to show websites in ChatGPT's search features.
• Sites that block OAI-SearchBot will not be shown in ChatGPT search answers, although they can still appear as plain navigation links.
• To help your site appear, OpenAI recommends allowing OAI-SearchBot in your robots.txt file. Robots.txt is a small text file on your website that tells crawlers what they may read.
• GPTBot is a different crawler, used to collect content for training OpenAI's models. You can block GPTBot and still allow OAI-SearchBot. The two settings are independent.
• After you change robots.txt, OpenAI says it can take about 24 hours for search to adjust.

That is the full list of what is documented. Everything else in this guide is common practice, and we say so where it applies.

How to check your robots.txt in two minutes:

1. Type your web address followed by /robots.txt into a browser, for example yourbusiness.com.au/robots.txt.
2. Look for a line that says "User-agent: OAI-SearchBot" or "User-agent: *" followed by "Disallow: /". That combination blocks the crawler from your whole site.
3. If you see it, or the page is empty and you are not sure, ask whoever built your website to allow OAI-SearchBot.
4. Also ask them whether a security tool or firewall blocks unknown bots. Some do this by default, and that can block OpenAI even when robots.txt allows it.

An afternoon checklist for a service business

Here is what we would do first, in order. Step 1 is documented by OpenAI. Steps 2 to 8 are common practice across the guides we read, and step 6 follows Google's own advice for local businesses. None of them comes with a guarantee.

1. Check robots.txt and your security settings (above). Documented by OpenAI.
2. Put a clear answer under each service heading. If the heading is "How much does a blocked drain cost?", the first sentence should give a price range and what changes it, not a story about your history.
3. Give every service its own page, with the suburbs or city you cover and prices where you can show them. A page that says "plumbing services" is harder to quote than one that says "hot water system replacement in Geelong" and gives a price range.
4. Add an FAQ section written in your customers' words. Use the questions people actually ask you on the phone.
5. Make your business name, address and phone number the same everywhere: your site, Google, Facebook, directories. Small differences make it harder for any machine to be sure they are all you.
6. Complete your Google Business Profile and ask happy customers for reviews. Google says local results are based mainly on relevance, distance and prominence, and that more reviews and positive ratings can help your local ranking (Google Business Profile Help). Google also says there is no way to pay for a better local ranking.
7. Get listed in the directories your trade or profession uses, and in your industry association's member list. These are the trusted sites that answers often draw on.
8. Keep pages up to date and show a "last updated" date on guides and price pages.

If you would rather someone ran this check for you, we do it as part of a free audit call: we look at what AI engines say about your trade in your area and where your enquiries leak.

Do schema markup and llms.txt matter?

Schema markup is code on your page that labels things for machines: this is the business name, this is the phone number, these are the opening hours, this is an FAQ. It helps search engines read a page without guessing. Many website builders add the basic version for you. It is worth having, but it is not a switch that gets you named.

llms.txt is a proposed file that sits on a website and summarises it for AI tools (llmstxt.org). It is a proposal, not a standard that OpenAI has adopted. Several guides recommend it. We found nothing from OpenAI saying ChatGPT uses it, so treat it as low cost and low priority: fine to add, not worth paying for.

Our generative search readiness checklist goes through the technical side in more detail.

How to check who ChatGPT names for your service

You don't need a paid tool to see where you stand. You need a spreadsheet and about an hour a month.

1. Write down 10 questions your customers actually ask. Mix three kinds: "best [service] in [suburb]", "how much does [job] cost in [city]", and "what should I do if [problem]".
2. Ask each question in ChatGPT, Gemini and Perplexity. Use a private or logged-out window where you can, so past chats don't shape the answer.
3. For each answer, write down every business it names and every website it links to.
4. Count how often you are named, how often your site is linked, and which competitors keep coming up.
5. Repeat on the same day each month with the same questions. The trend matters more than any single answer.

Here is an illustration with made-up numbers, not a client result. Say an electrician in Ballarat runs the check: 10 questions in 3 engines gives 30 answers. A competitor is named in 9, a directory site is linked in 12, and our electrician is named in 1. That tells them two things. First, the directory matters, so their listing there should be complete. Second, the competitor is doing something worth studying: look at their service pages, reviews and listings.

Keep the questions the same, or you can't compare one month with the next.

Does ChatGPT use Google rankings?

Not directly, as far as OpenAI documents. ChatGPT search uses OpenAI's own crawler, OAI-SearchBot, to find and show websites (OpenAI). OpenAI does not publish a rule that says it copies Google's order.

In practice, businesses that do well in Google often show up in AI answers too. That is probably because the same things help both: clear pages, a complete business profile, reviews and mentions on trusted sites. You will see guides quote studies on how much Google and AI answers overlap. We did not include those numbers because we could not open the original studies to check them.

The practical view: don't run two separate strategies. Good basics for Google are most of what you need for ChatGPT. For more on how the two fit, read AI discoverability for service websites.

What to skip

Some things are a waste of money, or worse:

• "Guaranteed ChatGPT ranking" offers. There is no position to guarantee, and no paid way to buy a mention in the answers themselves.
• Fake or bought reviews. They break the platforms' rules and can get your profile suspended.
• Keyword stuffing: repeating "best plumber Melbourne" twenty times on a page. It makes the page worse for people and gives AI nothing useful to quote.
• Rewriting your whole site for AI. Fix the pages that matter (your main services) first.

One last point, because it is where most of the money is. Being found only pays if you answer quickly. A Harvard Business Review study of 2,241 US companies found only 37% replied to a web enquiry within an hour, and firms that replied within an hour were nearly seven times as likely to qualify the lead as firms that waited an hour longer (SmartCompany's summary of the study). These were US web enquiries, so treat the numbers as a direction, not a forecast. If ChatGPT sends you a customer and you call back tomorrow, someone else gets the job. Read speed to lead and the 5-minute lead response rule, or put your own numbers into the Lead Response Calculator to see what slow replies cost you.
