Right now, across AI search, 85% of business categories don’t have a clear owner. No brand shows up consistently when people ask the obvious questions. That sounds like a wide-open field.
Here’s the part that changes the math: when a brand does take a clear lead in a category — and holds it by a real margin — it keeps that lead 90% of the time, month after month.
So the real picture isn’t “wide open.” It’s two very different games happening at once. In most categories, the race hasn’t been decided. In the rest, it’s already over.
The question that matters for your business: which game are you actually playing?
Hi, I’m Jeff Payne. You’re listening to The Jeff Payne Show, Episode #35: The Category Is Already Taken.
When we talk about “owning a category” in AI search, here’s what we mean, concretely: there’s a cluster of questions your buyer asks — what is it, who does it, who’s the best, what’s the alternative, how do I choose — and when they ask an AI system, one name keeps coming up as the answer. Not a source in a footnote. The name inside the sentence.
New data from SEMrush’s AI Visibility Toolkit — tracking over a thousand categories across six months — shows this ownership is remarkably sticky once it’s real. A narrow lead flips constantly. A wide lead, once established, is close to permanent.
Here’s what should unsettle you about this data. The metrics you’ve spent years optimizing — domain authority, organic traffic — barely predict who wins the category. They’re close to a coin flip.
The one signal that actually correlates is branded search demand — people already searching your name. Which means AI ownership isn’t rewarding your SEO history. It’s rewarding whether you were already known before the AI got involved.
And there’s a second twist. The brand that gets cited as a source and the brand that gets mentioned as the answer are usually not the same brand. Only one in five times do they match. In fact, the two numbers move slightly against each other. You can win the footnote and lose the sentence. Most companies are optimizing for the footnote.
Dr. Kamran Haghighat, a periodontist in Portland, is close to a real-world version of that 90% retention number. We’ve worked with him for about a decade. Over that time, we’ve built and published more than a hundred real patient stories — not testimonials, actual documented outcomes — and today, across the high-intent searches a prospective patient in Portland would run, his name is the one that keeps showing up as the answer.
That didn’t happen from a keyword campaign. It happened because ten years of consistent, verifiable proof gave AI systems — and Google before them — a name to attach to the category, and once that attachment formed, it’s held.
If your category is among the 85% still undecided, the opportunity isn’t about content volume. It’s building a margin wide enough that once you take the lead, it holds — because narrow leads don’t survive.
If your category already has an owner and it isn’t you, the retention number should tell you something uncomfortable: this isn’t a content problem you’re outspending. It’s a proof problem you have to out-build.
And if you are the owner — the 15% — the work isn’t finished. Defending the position means watching three fronts at once: whether you’re still the name in the answer, whether you’re still a trusted source behind it, and whether the outside world — the press, the reviews, the third parties — still backs up the story AI is telling about you.
Most categories are still up for grabs. But the ones that aren’t — those are already taken. And the data says ‘taken’ means ‘taken for a long time’.
The question isn’t whether your category has been decided yet. It’s whether you’re building toward a lead wide enough to survive the decision — or hoping nobody notices you haven’t.
Thanks for listening. See you next time.

WHAT “OWNING A CATEGORY” ACTUALLY MEANS
When we talk about owning a category in AI search, here’s what we mean, concretely: there’s a cluster of questions your buyer asks — what is it, who does it, who’s the best, what’s the alternative, how do I choose — and when they ask an AI system, one name keeps coming up as the answer. Not a source in a footnote. The name inside the sentence.
New data tracking over a thousand categories over 6 months shows this ownership is remarkably sticky once it’s real. A narrow lead flips constantly. A wide lead, once established, is close to permanent.
| Category Status | Next-Month Retention |
|---|---|
| Clear owner (5+ point lead) | 90.4% |
| Emerging leader | 63.4% |
| Unsettled category | 51.5% |
| All categories (average) | 61.5% |
In most categories, the race hasn’t been decided. In the rest, it’s already over.
Why YOUR SEO METRICS WON’T SAVE YOU
Here’s what should unsettle you about this data. The metrics you’ve spent years optimizing — domain authority, organic traffic — barely predict who wins the category. They’re close to a coin flip.
The one signal that actually correlates with category ownership is branded search demand — people already searching your name.
And there’s a second twist. The brand that gets cited as a source and the brand that gets mentioned as the answer are usually not the same brand. Only one in 5 times do they match, and the two metrics carry a slight negative correlation. You can win the footnote and lose the sentence. Most companies are optimizing for the footnote.
PROOF, OVER A DECADE
Dr. Kamran Haghighat, owner of Portland Perio Implant Center, who is a periodontist in Portland, Oregon, is close to a real-world version of that 90% retention rate. We’ve worked with him for about a decade. Over that time, we’ve built and published more than 100 real patient stories — not testimonials, actual documented outcomes — and today, across the high-intent searches a prospective patient in Portland would run, his name is the one that keeps showing up as the answer.
That didn’t happen from a keyword campaign. It happened because ten years of consistent, verifiable proof gave AI systems — and Google before them — a name to attach to the category, and once that attachment formed, it’s held.
AI ownership isn’t rewarding your SEO history.
It’s rewarding whether you were already known before the AI got involved.
THE MOVE
If your category is among the 85% still undecided, the opportunity isn’t about content volume. It’s building a margin wide enough that once you take the lead, it holds — because narrow leads don’t survive.
If your category already has an owner, and it isn’t you, the retention number should tell you something uncomfortable: this isn’t a content you outspend. It’s a proof problem you have to out-build.
If you are the owner, the work isn’t finished. Defending the position means watching three fronts at once: the answer, the sources behind it, and the outside world’s proof that backs up the story AI is telling about you.
Most categories are still up for grabs. But the ones that aren’t — those are already taken. And the data says taken means taken for a long time.
The question isn’t whether your category has been decided yet. It’s whether you’re building toward a lead wide enough to survive the decision — or hoping nobody notices you haven’t.
