You search Google for one of the services you most want to be found for, and there you are. Your business has held a strong position for months. You know the page is being found, people are visiting it, and whatever else is going on with your marketing, Google visibility isn’t the obvious problem.
Then you ask ChatGPT to recommend businesses that do much the same work. Several names come back, but yours isn’t one of them.
That feels particularly baffling because you already have evidence that the business is visible online. You’re not starting with, “Can anyone find me?” Google apparently can, and rather well.
So what is ChatGPT seeing differently?
The different result isn’t a diagnosis. A strong Google ranking tells you something real about how that page is performing in Google. It doesn’t mean ChatGPT has to produce the same set of businesses when somebody asks it for a recommendation.
Research comparing Google results with AI visibility points in the same direction. There is overlap between the 2, but nowhere near enough to assume that a strong Google position will carry across neatly into ChatGPT.
A note about these guides
AI visibility is a complicated and fast-moving area, and many of the confident answers you’ll find online become considerably less certain once you look at the evidence behind them. These guides are deliberately detailed because I want to explain what we know, what we’re still working out, and what that means for an individual business. If you want the shorter version first, start with What you need to know below.
If an important service page ranks strongly in Google, I wouldn’t brush that aside simply because ChatGPT gave you a different answer.
Google says its search systems use many factors and signals to work out which results are relevant and helpful for a particular query. Ranking generally works at page level, although site-wide signals also contribute.[1]
So if your succession-planning page regularly appears near the top when someone searches for a consultant who helps family businesses with succession planning, that is meaningful evidence.
Google can find the page and considers it relevant enough to rank highly for that search. And if the ranking has held over time, this isn’t one lucky appearance in AI search.
But that ranking has limits. It doesn’t mean every service your business offers is equally easy to find, every related search will produce the same result, or another search or AI system will present the business in the same way.
Take a management consultant who ranks well for a page specifically about succession planning in family-owned businesses.
Now imagine someone asks ChatGPT:
Who can help the owners of a family business plan a gradual handover to the next generation?
The need is very close to the one behind the Google search. But we’re no longer looking at a ranked Google results page. We’re looking at a ChatGPT answer that gives the person a much smaller selection of businesses.
The Google result still tells us that the page is performing well in Google. We’re simply asking it to prove something it can’t.
It’s tempting to explain the mismatch by saying the person is asking Google and ChatGPT different questions. Sometimes they are. But someone can be looking for much the same thing in both places and still get a different set of businesses.
One 2025 study tried to test exactly that. Researchers took 1,000 Google searches across 5 commercial categories and turned them into conversational ChatGPT prompts designed to ask for much the same thing. They then compared the brands in Google’s first-page results with those in ChatGPT’s answers.[2]
The overlap averaged around 61–62%. In other words, there was plenty of common ground and a substantial amount that didn’t match. The exact position of a brand in Google was an even poorer guide to where it appeared in the ChatGPT answer. The correlations were close to zero.
This study doesn’t give us a universal rule for small service businesses. It looked at 15 large brands across insurance, credit cards, hotel booking, web hosting and online courses. The ChatGPT tests also used a controlled API setup with standardised prompts and answer formatting, which is not the same as reproducing everything somebody sees in the consumer ChatGPT product.
Even with those limits, it supports the point we need here:
Businesses appearing prominently in Google and businesses appearing in ChatGPT won’t necessarily form the same list, even when both searches are asking for much the same thing.
That helps us rule out some of the tidy explanations that sound convincing until you look at them closely.
“Google ranks pages while ChatGPT ranks businesses”, for example, has a satisfying neatness to it. Unfortunately, neatness isn’t evidence. What we can say is that Google and ChatGPT can draw on some of the same web information and still give you different results.
Which raises the next question: if the results can differ, does conventional SEO still count for anything?
A newer study from August 2026 adds another piece to the picture.
For more than 9 in 10 brands in its dataset, stronger conventional search authority broadly tracked with stronger AI visibility. Brands with a stronger search presence generally appeared more often in AI answers.[3]
The outliers are where the picture gets less tidy. Some brands with very strong traditional-search metrics appeared surprisingly little in AI answers, while others appeared far more often than their Google and SEO presence suggested.
So SEO hasn’t been shown the door and told to collect its things. The study gives us no reason to throw out everything that already helps a business perform well in Google. It does show that Google performance won’t tell you exactly what will happen in ChatGPT.
The August study measured something broader. It compared brand-level search metrics with visibility across GPT-4o, Gemini 2.5 Flash and Claude Sonnet 4.6 rather than pairing one exact Google ranking with one matching search in the consumer version of ChatGPT.
So we can’t use it to claim that a particular Google position should produce a particular ChatGPT result.
Even with that limit, the outliers show that a brand can have very strong conventional search signals and appear much less often in AI answers than those signals led the researchers to expect.
And once you keep seeing that kind of mismatch in your own searches, it’s time to investigate it.
This is where it’s very easy to get ahead of the evidence.
You rank well in Google, ChatGPT leaves you out, and you start comparing the businesses it does mention. One has more reviews. Another appears in 4 industry directories you don’t. A third has more articles, different service wording and more third-party mentions.
Give it half an hour and you can have a very impressive collection of differences while still having no idea which of them, if any, explains the result.
The mismatch between Google and ChatGPT gives you a better starting point for deciding what to check.
One missing ChatGPT answer doesn’t give us much to explain yet.
If the business appears for one closely related discovery question, disappears for another and comes back for the third, that is very different from being consistently absent across a small group of searches that all describe much the same service or need.
You don’t need hundreds of prompts and a dashboard large enough to scatter your brain. You need enough checking to establish whether you’re seeing a repeated pattern rather than one result.
Suppose our management consultant’s succession-planning page performs extremely well in Google.
What happens when you look elsewhere?
Does the homepage make that part of the business equally easy to see?
Do major public profiles connect the consultant with family-business succession?
Do interviews, directories or other websites describe the same work, or do they present the business much more broadly?
OpenAI hasn’t published a rule requiring all of these places to say the same thing.
But if Google is ranking one highly relevant page while the rest of the information online barely connects the business with that service, we have found a real difference to examine.
We still haven’t proved that it caused the ChatGPT result. At least we’re now looking at something connected with the result we’re trying to explain instead of collecting another list of generic AI-search tactics.
The August 2026 study found another interesting pattern.
Some brands had strong conventional visibility and the models clearly recognised them, yet they hardly appeared when the researchers searched within particular categories. The researchers described these as apparent categorisation gaps.[3]
Think back to our management consultant. ChatGPT can know exactly who the consultant is when asked by name and still leave the business out of searches for specialists in family-business succession. The study can’t tell us that this is what happened to your business. It gives us a more specific question to check:
Across the website and the other places the business appears online, is it consistently described as providing that service?
The same August study found an association between stronger AI visibility and greater third-party category coverage among some of the brands that appeared more often than their conventional search metrics suggested.[3]
An association isn’t proof that those third-party mentions caused the businesses to appear more often.
For your own business, though, it gives you another direct comparison to make.
If the same 3 businesses repeatedly appear for the searches you care about, and other websites consistently describe them as providing that particular service while your business barely appears outside its own website, I’d look at that difference more closely.
If the information elsewhere is very similar, that explanation becomes weaker.
Each comparison should narrow the possibilities. Spotting a difference doesn’t mean you’ve found the cause.
| What you’re seeing | What it gives you reason to check |
|---|---|
| Strong Google visibility, repeated ChatGPT absence | Whether the gap holds across a small group of closely related discovery searches |
| A high Google ranking concentrated on one service page | Whether the rest of the information online makes the same service connection easy to see |
| ChatGPT recognises the business by name but often leaves it out for the category | Whether the business is consistently described as providing that service |
| The same competitors repeatedly appear | Whether there are consistent differences in how those businesses are described elsewhere online |
None of those observations arrives with “and therefore this is the cause” attached.
If only AI-search advice were generally that considerate.
You already have something to protect. A service page that ranks well for an important Google search and brings the right people to your business is already doing exactly what you need it to do.
I wouldn’t start rewriting that page because ChatGPT left the company out of a few recommendations. If the evidence later points back to the page, you have a reason to change it. “ChatGPT didn’t mention me” isn’t enough on its own.
The same applies to all the fixes that start appearing as soon as you search for advice about AI visibility.
You don’t yet know that you need:
more articles;
more third-party mentions;
different service terminology;
more directory listings;
schema changes;
a collection of FAQs;
or whichever AI-search tactic has acquired a confident explanation this month.
The visible difference isn’t automatically the cause.
Suppose the consultant’s succession page ranks strongly, attracts the right enquiries and explains the work in specific terms. Then, after noticing that ChatGPT doesn’t include the business, the owner broadens all the wording because a recommended competitor uses a broader category description.
The page is now less specific for the people who were already finding it through Google, and we still haven’t established that the wording had anything to do with the ChatGPT result.
A known asset has been changed to solve a problem we haven’t pinned down.
The job now is to work out what, if anything, needs changing without rebuilding everything that was already doing its job before you asked ChatGPT the question.
At some point, of course, the investigation has to lead somewhere.
The answer can’t always be, “Interesting. Let’s gather another 400 data points.”
I’d be much happier changing something when several pieces of evidence begin pointing in the same direction.
You keep seeing the same gap across searches that real potential clients would use, and when you follow that pattern, the same specific problem keeps turning up in more than one place.
Whatever you change should connect directly with that problem rather than with a theory about what AI supposedly likes.
There’s another test I use:
Would the change still help customers if ChatGPT disappeared tomorrow?
If a service page is vague and customers would also benefit from a more specific explanation, improve it.
If an old public profile is giving the wrong service information, correct it whether or not an AI system ever sees it.
Of the website and other public sources describe the business in conflicting ways, clean that up for the people trying to work out what you actually do.
And sometimes the Google performance is strong, ChatGPT results are inconsistent, competitors rotate from one test to another and nothing keeps pointing to the same problem.
Doing nothing for now is a completely legitimate outcome.
There is a peculiar pressure around AI search to assume that every unexpected result requires action. A better look is sometimes all the result has earned.
If you want to investigate this yourself, start with a small set of realistic discovery searches and compare the pattern with what is already working in Google. Follow the differences only where the evidence gives you a reason to.
And if you’d rather have the searches, website, public sources, competing businesses and inconsistencies investigated together, that’s what my AI Visibility & Accuracy Audit is designed to do.
The goal is to explain why the Google and ChatGPT results don’t line up, decide whether the difference is consistent enough to act on, and change only what the evidence supports.
Ranking well in Google and appearing in AI search are related, but they are not the same thing.
Strong SEO gives AI systems useful signals and makes your business easier to find, but it does not guarantee that ChatGPT will include you when someone asks for a recommendation.
The customer’s wording, how your business is categorised, the public information available about you and the particular AI platform can all affect what appears.
If the mismatch keeps happening across relevant searches, investigate the pattern before assuming your SEO needs fixing.

[2] Chatoptic: SEO ≠ GEO: Only 62% overlap between Google ranking and ChatGPT visibility. The 2025 study compared 1,000 Google searches with conversational ChatGPT prompts across 15 brands in 5 commercial categories and found roughly 61–62% brand-presence overlap. Exact Google position showed very little relationship with position in ChatGPT responses. The study used a controlled API-based setup with standardised outputs, so it should not be treated as a replica of consumer ChatGPT or as a universal measurement of Google and ChatGPT overlap.
[3] Search Engine Land: The AI visibility index: Which brands are vanishing from AI search?. Fractl’s August 2026 analysis compared conventional search strength with AI visibility across brands using GPT-4o, Gemini 2.5 Flash and Claude Sonnet 4.6. More than 9 in 10 brands broadly followed the expected relationship, while a minority substantially underperformed or overperformed in AI. The study also reported apparent categorisation gaps and an association between third-party category coverage and stronger AI visibility. Those findings are observational and do not prove that category wording or third-party mentions caused the results.
