On 22 August 2026 we put seven buying questions to seven answer engines and read the sources off all 49 answers. The headline is that nobody owns these answers. The engines cited 139 distinct domains between them, no domain was cited by more than five of the seven, and two thirds of everything cited was cited by exactly one engine.
That matters more than which brand came top, and it is the opposite of what the organic search results for the same questions look like.
What we asked, and what it cost
Seven questions, chosen because they are what somebody types right before they spend money in this category:
- What is the best Semrush alternative for a solo founder?
- What is the best AI visibility tool?
- What is the best AI Overview tracker?
- Which tool tracks whether ChatGPT mentions my brand?
- What is the cheapest SEO tool that also tracks AI visibility?
- What is the best generative engine optimization tool?
- What are the best Peec AI alternatives?
Each went to Google AI Overviews, ChatGPT, Perplexity, Gemini, Google AI Mode, Microsoft Copilot and Claude. All 49 answers came back. The provider cost was about fourteen cents in total, which is the sort of number worth stating because it tells you how repeatable the work is.
Two things this sample is not. It is not longitudinal, so it says nothing about whether these answers are stable week to week. And seven questions is a small set, deliberately, because they are the seven that carry buying intent rather than seventy that mostly do not.
No incumbent, and that is the finding
Here is how the citation attention was distributed across the 139 domains:
| Cited by | Domains | Who is up there |
|---|---|---|
| 5 of 7 engines | 3 | seranking.com, llmpulse.ai, useomnia.com |
| 4 of 7 engines | 6 | dageno.ai, kime.ai, workduo.ai, tryprofound.com, semrush.com, ahrefs.com |
| 3 of 7 engines | 11 | zapier.com, position.digital, frase.io, g2.com, reddit.com and others |
| 2 of 7 engines | 27 | |
| 1 engine only | 92 |
Read the top two rows again. llmpulse.ai and useomnia.com were cited by more engines than semrush.com and ahrefs.com were. Neither is a household name. Neither has a fraction of the backlink profile of the two companies below them in that table.
Compare that with the ordinary search results for the same terms. Page one for "ai visibility tool" is Zapier, Frase, Profound, Semrush, Backlinko and Ahrefs. That is a fight measured in years. The AI answer for the same question is spread across 139 domains with no leader, and the sites currently winning it are small tools with one good page.
The engines do not agree with each other
The variance between engines was larger than the variance between questions.
| Engine | Distinct domains cited | What stood out |
|---|---|---|
| Perplexity | 51 | The widest net by a distance, leaning on vendor documentation and comparison hubs |
| Google AI Overviews | 40 | Pulled from YouTube and Reddit ahead of any vendor's own pages |
| Claude | 31 | Independent review sites over vendors |
| Microsoft Copilot | 28 | Aggregator sites that barely rank in Google at all |
| ChatGPT | 27 | The only engine where a vendor's own domain out-cited every independent source |
| Gemini | 21 | Preferred how-to roundups to vendor pages |
| Google AI Mode | 20 | The narrowest, and the heaviest on Reddit |
The ChatGPT row is the one to sit with. It named Ahrefs in six of the seven answers and ahrefs.com was its single most repeated citation. On the same questions, Google AI Mode barely touched vendor domains at all. If you had measured one engine and reported it as "AI visibility", you would have been confidently wrong about the other six.
The brands that got named
Six brands were named by all seven engines: Profound, Peec AI, Otterly, Semrush, SE Ranking and Scrunch. But the per-question concentration is where the useful signal is.
On "the cheapest SEO tool that also tracks AI visibility", Otterly was named by all seven engines. Not most of them. All of them. That question is close to how we describe ourselves, and somebody else currently owns the answer to it outright.
On "the best Semrush alternative for a solo founder", SE Ranking was named by all seven, with Mangools and Ubersuggest close behind. Notably, Semrush itself was named by six of the seven engines in answer to a question about replacing Semrush.
We were named zero times
Across 49 answers, no engine named SEOBuilder. seobuilder.tech was not cited as a source by any of them either.
We are publishing that because the alternative is publishing a chart with our own logo on it, and because a measurement you only run when you expect to like the result is not a measurement. It is also the honest starting point: this is what a new site looks like in AI answers, and it is the number every future run gets compared against.
What to take from this
If you sell anything that a person might ask an assistant to recommend, three things follow.
One engine is not a sample. The spread above is the argument. A tool that watches only ChatGPT would have told us vendor domains dominate. A tool that watches only Google AI Mode would have told us Reddit does. Both would have been reporting an artefact of one retrieval system.
The citation game is open in a way the ranking game is not. A domain nobody has heard of can be cited by five of seven engines today. That will not stay true, and the reason to measure now is to know where you stand before it closes.
Check yours before you believe anybody's roundup, including this one. You can run the same question set by hand against each engine for nothing but your time. If you want it done for you, our free check asks Google AI Overviews and ChatGPT with no account, and the full method is written out here including how to reproduce it without paying us. SEOBuilder is our own product, so treat the recommendation accordingly.
The per-engine numbers above are also published on each engine's own page, so you can see what ChatGPT, Perplexity, Gemini, Google AI Mode, Microsoft Copilot, Claude and Google AI Overviews each cited on their own.
We will run this again. The interesting number is not where anybody sits today, it is which way the spread moves.
