ChatGPT SEO is the work of making your business easy for ChatGPT to find, trust and name when someone asks it for a recommendation. In practice that means three things: let OpenAI's search crawler into your site, put the facts a customer asks about in plain text on clear pages, and be described the same way in the other places ChatGPT reads. There is no setting or file that makes ChatGPT pick you, and anyone selling one is guessing.
That is the short answer. The rest of this guide separates what OpenAI documents from what everyone else is guessing, because most of what is written about ChatGPT SEO blurs the two. I make websites and sell SEO, so I have a stake in this. Where a fact comes from a source, I link it. Where it is my opinion, I say so.
What is ChatGPT SEO?
The phrase means two different things, and the search results mix them up.
- Getting your business into ChatGPT's answers. Someone asks "who fixes water heaters in Springfield?" or "what should I look for in a family dentist?", and ChatGPT answers with names and links. ChatGPT SEO, in this sense, is the work of being one of those names. This guide is about that.
- Using ChatGPT to do SEO work. Writing outlines, researching keywords, drafting page titles. That is a different job with its own risks, and I cover it in my guide to how to use AI for SEO.
You will also see the first meaning called GEO (generative engine optimization), AEO (answer engine optimization) or "LLM SEO". They are the same goal across every AI tool. My guide to answer engine optimization covers all of them; this one narrows it to ChatGPT, because that is the one people ask about by name.
How does ChatGPT decide which businesses to recommend?
OpenAI does not publish a ranking recipe. What it does publish is how its crawlers work, and that tells you more than most guides admit.
ChatGPT can answer in two ways. It can answer from what its model already learned in training, or it can search the web for that question and build the answer from the pages it finds. For a question about local businesses, prices or anything recent, the search is where your website comes in.
OpenAI runs separate bots for separate jobs, and it documents them on its crawler page (opens in a new tab):
- OAI-SearchBot is the one that matters for being recommended. OpenAI says it "is used to surface websites in search results in ChatGPT's search features," and that sites which block it "will not be shown in ChatGPT search answers, though can still appear as navigational links."
- GPTBot collects pages that "may be used in training" OpenAI's models. Blocking it does not block search: "Each setting is independent of the others," and OpenAI's own example is a site that allows OAI-SearchBot "to appear in search results while disallowing GPTBot."
- ChatGPT-User visits a page when a person asks ChatGPT to look at it. OpenAI says robots.txt rules "may not apply" to it because a user started the visit, and that it "is not used to determine whether content may appear in Search."
What happens after a page is fetched is not documented. Which of several plumbers gets named first, how much reviews weigh, whether a page's age matters: OpenAI has not said, and the lists of "ranking factors" you will find were mostly made by asking ChatGPT, which does not know how its own search ranks either.
One more thing guides state as fact. Most of them, including Semrush's guide (opens in a new tab), say ChatGPT's search draws on Bing's results. OpenAI's own wording is vaguer. Its help article on searching the web with ChatGPT (opens in a new tab) says ChatGPT search "sometimes partners with other search providers," sending them rewritten versions of your question, and for how those providers handle queries it links to Microsoft's and Shopify's privacy policies. Microsoft runs Bing, which is why most guides read it as Bing, but the page never uses the word or says how much of an answer comes from any provider.
I still tell clients to get into Bing. I do not search with Bing myself, and you may not either, but you never know what the people looking for your business use to search the web. It makes sense to be thorough and cover all the popular search engines, Bing included, even though it is not the most popular one. It costs nothing, and it helps whatever ChatGPT turns out to use.
Is ChatGPT SEO different from Google SEO?
Less than the marketing suggests. Both need a site that can be crawled, pages about the specific things people ask, and a reputation that holds up when checked. The differences are in what you win and how you can see it:
| Google search | ChatGPT answers | |
|---|---|---|
| What you win | A position in a list of links | Your name, and maybe a link, inside a written answer |
| The crawler to allow | Googlebot | OAI-SearchBot (GPTBot is separate and optional) |
| Is there a dashboard? | Yes, Search Console | No; you check the answers yourself |
| How repeatable is it? | Fairly stable from one search to the next | The same question can name different businesses each time |
| What you can control | Your pages, your Google Business Profile, links | Your pages, crawler access, how you are described elsewhere |
The row that changes how you work is the fourth. Google shows roughly the same results to the same search. ChatGPT writes a new answer every time, so one check proves little, and you judge it over many questions and several months. More on that in the testing section below.
How do you get ChatGPT to recommend your business?
These are the steps I work through, in the order they can block each other. The first one can zero out everything after it, so do not skip it because it sounds technical.
1. Let OAI-SearchBot in
Open yoursite.com/robots.txt in a browser. If you see a block for OAI-SearchBot with Disallow: /, ChatGPT search cannot show your pages. A file that allows it looks like this:
User-agent: OAI-SearchBot
Allow: /
User-agent: GPTBot
Disallow: /
The GPTBot lines are optional: they say "do not use my pages for training," which is a reasonable choice and does not affect search. OpenAI says a change to robots.txt can take "~24 hours" to reach its search systems.
Then check the service in front of your site, because robots.txt is not the only door. Firewalls and CDNs such as Cloudflare can challenge or block bots before robots.txt is ever read. OpenAI recommends "allowing requests from our published IP ranges" for OAI-SearchBot and publishes the list at openai.com/searchbot.json (opens in a new tab). Look for a bot or AI crawler setting in your firewall and make sure verified search crawlers get through. I tell the story of finding exactly this on my own site in Is your website agent-friendly?, and it is the most common silent failure I see.
2. Be in Bing and Google
Whatever ChatGPT searches, a page that no search engine has indexed is a page nobody's search will find. Both tools are free:
- Bing Webmaster Tools can import your site and its sitemaps straight from Google Search Console, and the imported sites are "automatically verified" (Bing Webmaster Blog (opens in a new tab)). Then look at which pages are not indexed.
- Google Search Console shows the same for Google. If key pages are "Discovered, currently not indexed," fix that first.
3. Put the facts customers ask about in plain text
When ChatGPT recommends a business, it is answering a question with constraints: a town, a price range, a service, a time frame. It can only match you to those constraints if your pages say them in words. That means a page for each main service, your service area written out by town, prices or price ranges where you can give them, your hours and how to reach you.
Facts that only appear inside an image, a PDF, a video or a widget that loads after the page are easy to miss. If your site was built with a page builder or an app-style framework, ask whoever built it whether the important text is in the page's HTML when it first loads. Mine is, on purpose.
4. Answer the question in the first sentence
An answer engine looks for the passage that settles the question. Give it one:
- Open each page and each section with the answer, then explain.
- Write headings the way customers ask ("How much does a water heater replacement cost?"), not as slogans.
- Be specific. "Most replacements cost between [your low price] and [your high price] installed, depending on tank size and venting" can be quoted. "Competitive pricing" cannot.
This is also just clearer writing for people, which is why I do not consider any of it wasted if the tools change.
5. Be described the same way everywhere
ChatGPT does not only read your site. When it recommends businesses, it is drawing on what the pages it finds say about them: directories, review sites, local news, trade associations, other businesses' pages and forums such as Reddit. That is also the most likely reason Reddit shows up in so many answers: it is where people describe businesses in their own words. I cannot show you OpenAI's weighting, so treat that as my reading, not a documented rule.
What you can control is consistency. Your business name, address, phone number, service list and service area should match on your site, your Google Business Profile, Bing Places and the directories your trade uses. A steady flow of genuine reviews helps everywhere. None of this is new; it is the same work that wins the map results, which is a good reason to do it first.
6. Earn mentions where ChatGPT already looks
Ask ChatGPT the questions your customers would ask and look at the sources it links under each answer. Those sites are your shortlist: the local paper, the directory, the association, the "best of" list. Getting listed, reviewed or quoted on them is slower than editing your own site, and it is often what separates the business that gets named from the one that does not. Semrush's guide recommends the same method, and it is the one tactic in this list that has no shortcut.
7. Skip the tricks
A few things are sold as ChatGPT SEO that I would not pay for:
- An llms.txt file as an "AI visibility" upgrade. It is a small text file that may help AI agents find your best pages, and it is worth half an hour once those pages are good. No AI company has said it uses the file to decide who to recommend. I cover it in What is llms.txt?
- Schema markup as a secret switch. Structured data removes doubt about who you are and is worth having. It is not a ChatGPT ranking lever that anyone has documented.
- Pages stuffed with "best plumber in Springfield." A page that only repeats a phrase gives an answer engine nothing to quote.
- Paying to appear. ChatGPT now shows ads: OpenAI runs a separate crawler, OAI-AdsBot, to check "web pages submitted as ads on ChatGPT." Ads may be worth testing, but they are advertising, not SEO, and they should be sold to you as that.
As of October 2026: OpenAI's crawler page (opens in a new tab) lists four agents: OAI-SearchBot (ChatGPT search; OpenAI recommends allowing it and its published IP ranges), GPTBot (training; independent of search), ChatGPT-User (visits a person asked for; robots.txt "may not apply") and OAI-AdsBot (checks ad landing pages; its data is "not used to train generative AI foundation models"). Robots.txt changes take "~24 hours" to reach search. OpenAI's help article on ChatGPT search (opens in a new tab) says it "sometimes partners with other search providers" without naming them in its text, and says placement in results "is not guaranteed."
What about local businesses?
Most of what is written about ChatGPT SEO is for software companies and online stores. A plumber, a dentist or a law office has a simpler job and a different one.
The question that matters to a local business is "who should I call for this, here?", and ChatGPT can only answer it with businesses it can tie to the place. So the local version of this list leans hardest on steps 3 and 5: your service area written out by town on your own pages, and the same name, address and phone number everywhere else, with reviews behind them. OpenAI says only that ChatGPT may share your location with "trusted third-party providers that help provide more local information, such as nearby business listings," without naming them, so I would not chase any single listing service. Keep them all accurate, starting with Google and Bing.
The other thing local businesses can do that national brands cannot is be the obvious answer to a narrow question. "Who repairs commercial walk-in coolers in Jackson?" has far fewer candidates than "best HVAC company," and a page that answers it plainly has a far better chance of being the one named.
What I see in my own tracking
I track my own business the way I would a client's, so here is real data rather than a theory. I use Ahrefs' Brand Radar to ask the same 20 questions a buyer might ask, such as who builds websites for veterinary clinics in Mississippi or who offers website care plans, across five AI engines: ChatGPT, Google's AI Overviews and AI Mode, Gemini and Perplexity. I read the results by hand on October 25, 2026, from the latest runs: the 24th for four engines and earlier in October for Perplexity.
Three things stood out:
- My site was cited in 16 of the 100 answers, and 12 of those were questions with my business name in them. On the other questions, where a stranger is asking for a recommendation, I was barely there. Being findable by name is the easy part. Being recommended is the work.
- The most-cited web designer in Mississippi does not rank in Google at all. One small studio was linked in 9 of the 100 answers while Ahrefs showed it ranking for zero Google keywords, with a Domain Rating of 11 (Ahrefs' 0-to-100 score for the strength of a site's links). Several others cited four to six times also ranked for almost nothing. Being recommended in AI answers and ranking in Google are related, but they are not the same contest, and a small business with clear pages can win the first without the second.
- My own firewall was in the way of unverified bots. On October 27, 2026, I requested my robots.txt and home page from a cloud server, once as a browser and once using OAI-SearchBot's name. Both got Cloudflare's challenge page instead. That is the right outcome for a fake bot using a real bot's name, and my security log shows OpenAI's verified crawler getting through, but it shows how easily the wrong setting could hide a site from the real one.
The numbers
| Kind of question | Answers that linked to my site | Share |
|---|---|---|
| Questions with my business name in them (3 questions, 15 answers) | 12 of 15 | 80% |
| Every other question (17 questions, 85 answers) | 4 of 85 | 4.7% |
These numbers are counts of links in answers, from one set of questions, on one date, pooled across all five engines rather than ChatGPT alone. They are not a study, and they will move. I will update this section as they do.
How do you check whether ChatGPT recommends you?
You can do this yourself once a month in about twenty minutes. The point is to ask the same questions the same way each time, so the results can be compared:
| Step | What to do | What to write down |
|---|---|---|
| 1. Pick the questions | Five questions a new customer would really ask, without your name in them ("who installs tankless water heaters in [your town]?") | The exact wording, so you can repeat it |
| 2. Ask in a clean chat | A new chat, with your saved memory and past chats kept out of it if your account allows, so your own history does not steer the answer | The date |
| 3. Ask each question twice | Answers vary between runs; two runs show you how stable a mention is | Who was named, in what order, and whether you were |
| 4. Open the sources | Click the links under each answer | Which sites ChatGPT cited; these are your step 6 shortlist |
| 5. Check your analytics | Look for visits from chatgpt.com in your referral traffic | The number, compared with last month |
On step 5, expect the analytics to undercount. Seer Interactive's tracking guide (updated June 2026) found that the links under ChatGPT's "sources" usually carry a utm_source=chatgpt.com tag while its search-result links do not, and that a visit arriving without its referrer is counted as Direct in Google Analytics (Seer Interactive (opens in a new tab)). Treat the chatgpt.com number as the floor, not the total. Paid tools such as Brand Radar and Semrush's AI Visibility Toolkit run the same check at scale; they measure, they do not fix, and a small business can start without one.
Who can skip this for now?
Not every business needs to spend time on ChatGPT yet. This part is my judgment:
- If nearly all your work comes from referrals and repeat customers who already know your name, the easy part is already done.
- If your site is missing the basics (a clear list of services, a service area, prices or price ranges, a way to get in touch), fix those first. They are most of what ChatGPT needs anyway.
- If someone is offering to "rank you in ChatGPT" for a monthly fee, ask them what they will change on your site and where they will get you mentioned. If the answer is a file, a plugin or a dashboard, keep your money.
If your customers find businesses like yours by asking a question, this is worth a few hours, and most of those hours also help you in Google.
The short version
- ChatGPT SEO means getting your business named in ChatGPT's answers. Using ChatGPT to do SEO is a different topic.
- Allow OAI-SearchBot in robots.txt and through your firewall. Blocking GPTBot is optional and does not affect search.
- Get indexed in Bing and Google; both tools are free.
- Put your services, service area, prices and contact details in plain text, and answer each question in its first sentence.
- Be described the same way on your site, your Google Business Profile, Bing Places, directories and review sites.
- Look at the sources ChatGPT cites for your customers' questions, and earn a place on them.
- Check monthly with the same questions, and judge the trend over months, not one answer.
