Even Brand Queries Are Not Owned by the Brand
When AI answers a question about your brand, it doesn't only read your website. In this AI brand visibility study — 15 brand and category queries run across ChatGPT and Perplexity — AI consistently pulled from third-party sources — review sites, retailer reviews, Reddit, YouTube — alongside, and sometimes above, the brand's own pages. Your owned content makes the claims; third-party sources make them believable, and AI seems to weigh the difference. That's the source gap most AI visibility and AEO audits miss.
A few weeks ago I went looking for a cat water fountain, mostly because I was tired of washing a water bowl every day. The problem: I found a dozen different recommendations and had no idea who to trust. Every site had a different "best" pick.
So I did what a lot of people do now. Instead of sorting through ten review tabs myself, I just asked ChatGPT and Perplexity.
The answers surprised me. When I asked about one specific brand, the AI didn't only repeat what the brand says about itself. It wove in Reddit threads, Best Buy reviews, a YouTube test, even a vet site — the same scattered sources I couldn't sort out on my own — into one confident answer.
That stuck with me. Even when I asked about one brand, AI did not let the brand speak alone. If I were that brand, I'd have assumed my own website controlled my story. It clearly didn't. So I ran a proper test.
This is an AI brand visibility study: I ran the same brand queries through ChatGPT and Perplexity and recorded every citation. The ChatGPT citations and Perplexity citations rarely came only from the brand. I publish the raw data as I go — the full 30-row dataset from this one is at the bottom of this post.

Key findings
- In this AI brand visibility study, the brand was named in 4 of 5 buying (solution-aware) queries and all 5 brand-aware queries, but in none of the 5 problem-aware queries — AI handed those to vets and health sites.
- The two engines split along familiar lines, repeating a pattern from my earlier ChatGPT vs Perplexity citation study: ChatGPT leaned more on owned and primary sources (petlibro.com, retailer pages), while Perplexity leaned more on review, media, and community sources (Forbes, cats.com, Reddit, YouTube).
- Even on brand-name queries, the answer was assembled from owned pages, review sites, retailer reviews, Reddit, and YouTube together — never the brand's site alone.
- The recurring source gap: third-party "witness" sources (independent reviews, Reddit threads, app-store ratings) shaped verdicts the brand's own pages couldn't.
What I tested
I picked one concrete consumer category — cat water fountains — and ran 15 real queries across three buyer stages (problem-aware, solution-aware, brand-aware). For the brand-aware ones I used PETLIBRO, a real pet-tech brand, as a public, outside-in example. Each query ran once on Perplexity and once on ChatGPT 5.5 (thinking mode + web search). I recorded every visible cited source.
Research note
Small, exploratory sample (15 queries, two engines, one run each), June 2026, visible citations only. This is an outside-in audit using public answers — not insider data, and not a benchmark. I name PETLIBRO but report only what the engines returned; I don't pass judgment on the brand. Treat it as an early signal worth retesting.
Who this matters for
Any brand, marketer, or founder who assumes that "ranking your own pages" is enough to control how AI describes you. This test suggests it isn't.
What I expected vs. what happened
I expected the brand's own site to dominate its own branded queries. It did show up — heavily so, especially in ChatGPT, which cited petlibro.com again and again. But the brand page did not control the answer. It was one source among many.
On brand-aware queries (PETLIBRO review, PETLIBRO vs PetSafe, is PETLIBRO good for cats, best alternatives to PETLIBRO), AI also pulled from:
- Review sites: cats.com, WIRED, Forbes, The Spruce Pets
- Retailer reviews: Best Buy, Chewy
- Community: Reddit (including r/Petlibro), YouTube
- Other: Similarweb, vetstreet
The brand page supplied specs and product framing. The verdicts, the comparisons, and the caveats came mostly from outside it.
The 3 source layers AEO has to account for
| Layer | Examples |
|---|---|
| Owned | Your website, product pages, docs, comparison pages |
| Earned | Review media, expert roundups, YouTube tests |
| Community / retail | Reddit, Amazon / Best Buy / Chewy reviews, app stores |
Most AEO audits stop at the owned layer. In this test, the earned and community layers did at least as much work in shaping the answer.
What I found, by query layer
| Query layer | Brand visibility | Sources AI used |
|---|---|---|
| Problem-aware | 0/5 (both engines) | Cornell, VCA, PetMD, iCatCare, Reddit, pet blogs |
| Solution-aware | 4/5 (both engines) | Forbes, WIRED, cats.com, ecommerce, brand pages |
| Brand-aware | 5/5 (both engines) | petlibro.com, cats.com, Best Buy, Reddit, YouTube |
The table is the whole story in miniature: visibility climbed from zero on problem-aware questions to total on brand questions. But at no stage did the brand's own pages stand alone.
What AI brand visibility looked like in the data
To be clear about method: I'm reporting what the engines surfaced, not my own judgment of the brand.
On buying queries (best cat water fountain, quietest, best smart fountain with app), AI consistently named PETLIBRO as a top or "best overall" pick. That's a strong owned-and-earned presence.
On brand questions, the engines also surfaced third-party material the brand doesn't control: Reddit threads, retailer reviews, and points such as filter cost and a mix of positive and negative reliability mentions. ChatGPT, for example, cited the brand's own page next to a dedicated third-party review and an app-store rating in the same answer.
The pattern wasn't "the brand is good" or "the brand is bad." It was that the answer was assembled from owned and third-party sources together, and a reader saw both at once.
This is not a one-brand problem
This isn't specific to PETLIBRO. It's how AI search works for every brand. Even a brand that wins visibility across most of its category does not own its own answer. The model reads the brand and the market in the same breath.
What I'd do to close these gaps
If I were improving this brand's AI visibility, I wouldn't start by rewriting product pages. I'd work the gaps in order.
1. Close the content gap: be useful before the purchase. The brand was invisible on problem-aware questions: why won't my cat drink, are fountains safe, how do I encourage my cat to drink more water? AI cited vets and health sites there, not brands. So I'd build genuinely useful, expert-reviewed content on cat hydration, water safety, cleaning routines, and when to call a vet — the questions buyers ask before they shop. The goal isn't to sell in that content. It's to earn a place in the answer where vets currently own it.
2. Close the source gap: earn what you can't publish. On brand queries, AI leaned on review sites, retailer reviews, and Reddit as much as the brand's own pages. You can't fake those, but you can earn them: get into the roundups AI already cites, make it easy for happy customers to leave real retailer reviews, and show up in the communities where buyers compare products. The aim is for the outside picture to match the story the brand tells about itself.
3. Decide which positioning gaps to fight. AI consistently handed certain attributes to competitors, like "easiest to clean" or "all-stainless." For each one, there is a choice: create evidence that changes the perception, or accept that the attribute belongs to someone else and double down on the positions the brand genuinely owns, such as quiet, smart, and app-tracked. Trying to win every attribute usually wins none.
4. Treat surfaced caveats as a to-do list. AI repeated specific third-party points, like app-store ratings, filter cost, and reliability mentions. The fastest way to change what AI says is to change what the market says. Some AEO fixes are content fixes. Some are review, support, product, or positioning fixes.
Then re-run the same 15-query test a month later and see what moved. AEO isn't a one-time audit. It's a measure, fix, re-measure loop.
Takeaway
If AI is answering questions about your brand, it isn't only reading you. It's reading what the market says about you.
So AEO can't stop at your owned pages. If the earned and community layers are thin, or say something different from your site, AI will surface that gap. The fix isn't only writing better product pages. It's earning third-party coverage, reviews, and community presence that match the story you want told.
In AI search, your brand page is your testimony. Third-party sources are your witnesses.
Your website can make claims. Third-party sources make those claims believable. AI seems to know the difference.
The full dataset (all 30 results)
Every query, both engines, recorded by hand on 2026-06-26. "Gap" is my categorization of where the brand was missing or losing the answer: Content (brand absent, authority/vet sources own it), Positioning (brand present but an attribute went to a competitor), Source (brand present, but third-party reviews/community shaped the verdict), or None.

FAQ
How do I improve brand visibility in AI answers?
Start by auditing which sources AI actually cites for your brand queries — owned pages, review media, retailer reviews, Reddit, YouTube, and app stores — then close the gaps in order: publish genuinely useful pre-purchase content, earn coverage in the review sites and roundups AI already cites, and fix the real-world signals (reviews, ratings, support) that third-party sources repeat back. Then re-run the same queries a month later to see what moved.
Does my own website still matter for AI search?
Yes. In this test the brand's pages were cited heavily, especially in ChatGPT. They just weren't the whole answer — AI assembled owned pages and third-party sources together.
Which third-party sources show up most?
In this sample: review sites like cats.com, WIRED, and Forbes; retailer/review surfaces like Best Buy and Chewy; and community/video sources like Reddit and YouTube.
How do I improve my "earned" and "community" layers?
Earn coverage in the roundups and review sites AI already cites, get your product into real retailer and Reddit discussions, and make sure independent tests (including on YouTube) exist. The point isn't to manufacture reviews; it's to make sure the honest third-party picture matches the story your own pages tell.
Is one run per query enough to trust this?
No. It's an early signal. The value is the repeated pattern across 15 queries and two engines, not any single answer.
