Spend a fortnight running AI visibility audits across one category — supplements, in this case, a category we know well — and you expect to find patterns. What you don’t expect is for the pattern to be this consistent.
Here’s the headline. The brands that show up in ChatGPT and Perplexity aren’t always the biggest. They’re not the ones with the best SEO scores, the most backlinks, or the highest organic traffic. They’re the ones whose product information is consistent across surfaces. The blog says the same thing as the product page. The reviews use the same vocabulary as the schema markup. The comparison content matches the language a real buyer uses when they ask an AI for a recommendation.
That’s it. That’s the whole pattern.
The shape of the gap
The brands that don’t show up — including genuinely well-known names with real customers and real revenue — have rich, beautifully designed sites where every page tells a slightly different story. Different ingredient claims here, different mechanism language there, different dosage framing in the FAQ. The homepage positions the brand one way; the product page another. The blog post written by the in-house nutritionist uses one set of words; the comparison page written by the SEO team uses another.
A human reader doesn’t notice. A human reader probably appreciates the variety.
An AI assistant trying to summarise the brand in roughly two hundred tokens notices. What it sees is contradiction. So it hedges, or it omits — and recommends someone simpler.
The most striking part isn’t that this happens. It’s the size of the gap. Some of these brands have spent years and serious budget on SEO and content — paid teams, agencies, tooling. On every measure that mattered five years ago, they are the content brand in their category. But search rewards depth and breadth; AI search rewards coherence. Those are different optimisation targets, and a site built for the first is not automatically good at the second. Repeatedly, the brand with the deepest content library was being beaten by a smaller competitor whose entire site was a handful of crisp, repeating, machine-readable claims.
Why the judge changed
Classic SEO had a forgiving judge. Google could tolerate internal inconsistency on a domain because its ranking system was built on signals between pages — links, anchor text, query-to-page matches. A clever brand could win those signals without ever resolving its internal contradictions.
An AI assistant is a far less forgiving judge. It has to say something coherent about your brand in two sentences, often with no prior context, under a token budget. If the source material disagrees with itself, the assistant doesn’t pick one version and commit. It hedges, omits, or picks the brand next door whose material doesn’t disagree with itself.
The brands performing well in AI answers aren’t winning on volume. They’re winning on agreement with themselves.
There’s a kicker in the audit data, too: the brands that did the least SEO theatre — where one person wrote the words and made sure they matched — are often doing best in AI answers. The brands that did the most are often doing worst. Not always. But often enough to be a pattern. Some of those winners almost certainly didn’t optimise their way there; they just had a clear voice that propagated.
The two-minute test
Open ChatGPT. Type “best [your category]”. Then “best [your category] for [your most distinctive use case]”. Then ask it to compare two named SKUs — yours against a direct rival.
If your brand isn’t in the first three results across those depths, the question isn’t whether you have enough content. You almost certainly do. The question is whether your content agrees with itself. Run the same test for your closest competitor while you’re there — it tells you who the AI has decided is the canonical voice in your space, and whether you’re in the running for the slot.
The implication for anyone building now is stark. Treat AI visibility as another optimisation layer on top of existing SEO and you’ll spend money without moving much. Treat it as a coherence problem — does my site agree with itself about what I am? — and you can get traction with surprisingly little volume. That’s the bet Geoffy is built on, and every audit strengthens it.
