AI recommends whoever the rest of the web is already writing about.

Whoever the AI names, wins

Search is splitting in two. Alongside Google's blue links, ChatGPT, Perplexity, Gemini, Copilot and Google's own AI answers now hand people a short list of brands and a few cited sources. Whoever the AI names makes the buying shortlist — and almost everything the marketing world "knows" about how that list gets made is folklore.

So we measured it. We took ~1,000 real commercial buyer questions across 15 industries and ran each through six engines, capturing which brands got recommended, which sources got cited, and the full page behind every citation. Then we did the one thing no visibility tool does: we joined it to what's actually inside the AI's training data — so we could tell whether a brand is recommended because the model learned it long ago, or because it's being read about right now.

11,573 answers · 15 industries · 6 engines · 8,784 brands · 18,422 domains cited · 36,413 pages read. Every query was run twice on each engine; the collection was stress-tested by five independent reviews before we spent a dollar; every headline number survived a check that it wasn't a quirk of measurement.

The sites AI trusts — and they're not who you'd guess

Two sources sit at the top of nearly every industry: Reddit and YouTube. Then each industry has its own short list of authority sites.

A brand's own website rarely wins a citation. You get cited by being written about elsewhere — on user forums, video reviews, and the specific outlets AI leans on for your sector.

The engines even prefer different kinds of sites. ChatGPT and Perplexity lean on independent reviews and comparison sites; Google's AI Overviews and AI Mode lean far more on brand- and vendor-owned pages. Reddit/YouTube-style content is a quarter of Google AI Overviews' citations but almost none of Copilot's.

AI cites who wrote about you, not you.

Which sites are you missing from?

Because we captured the full text of every cited page, we can do the thing that actually matters: for any brand, show the cited sites its competitors appear on and it does not — a ranked "get featured here" list. Here's a real one for ClickUp in software:

That output is the earned-media plan: the exact authority sites to get ClickUp featured on so AI starts recommending it — ranked, and tagged by whether the placement is durable (deep in the training data, lasting) or retrieval-dependent.

Winning search rankings isn't enough

Nearly three-quarters of what AI cites doesn't rank on Google's first page.

We captured the ordinary Google results for every query alongside the AI answer. Only 26% of AI citations come from a domain on Google's first page; 73% come from outside the top ten entirely — Reddit threads, YouTube videos, niche sites that don't rank but do get cited.

You can't just win search rankings and expect AI to cite you.

There's a flip side worth naming honestly: domains that do rank #1 on Google also get cited by AI 93% of the time. That's a strong overlap — though it's mostly because authoritative sites tend to both rank and get cited, not proof that ranking causes the citation. Either way, chasing rankings alone leaves most of the AI-citation pool untouched.

There's no "optimizing for AI." There are six different jobs.

The engines agree only a third of the time — and each gives a different answer every time you ask.

Two things jump out. First, there's no single number to plan around: the source count runs from 5 (Copilot) to 25 (Google AI Mode) — it's an engine-by-engine question. Second, and bigger: ask the chat engines the identical question twice and roughly half the recommended brands change. AI recommendation isn't a fixed ranking; it's more like a lottery you can improve your odds in. For anyone tracking their "AI visibility," a single check is meaningless.

One check is noise. Measure across engines, multiple times.

Baked-in vs. borrowed brands

By joining recommendations to the AI's training data, we can split every brand in two: recommended and deeply present in the training data — an incumbent the model knows cold — or recommended despite being nearly absent from it, winning purely on what the engine is reading right now.

A brand-new company can win AI recommendations today — on visibility, not fame.

These "borrowed" brands are recommended heavily while almost absent from the training data — a sign that current visibility, not incumbency, is driving the wins. It's the same story the industry-level finding tells, where 85% of recommendations already go to brands outside the top five.

To test that head-on, we did something only an open model allows. We took OLMo 2 — the one capable AI whose exact training data is public — and asked it the same buyer questions with its web access switched off, so it could answer only from memory. It recommended the corpus-heavy incumbents 4.6× more often than the borrowed brands, and it named none of the five borrowed brands above — not SE Ranking, TP-Link Tapo, Omnisend, Petlibro or Orthofeet — a single time from memory. They win inside the live engines while a model trained on the open web doesn't know them from memory at all. That's the cleanest evidence we have that the borrowed wins come from what the engines are reading right now, not from fame.

Reword the question, change half the answer

Phrasing isn't a rounding error. It's a lever you control.

We ran a controlled test: take the same buyer intent, ask it several ways (a question vs. a keyword, formal vs. casual, synonyms), hold the meaning constant, and watch what changes. Rewording the same question changed roughly half the recommended brands. So the content and coverage you earn should target the specific ways your buyers actually ask — not one tidy keyword.

Being useful beats being famous

85% of AI recommendations go to brands outside their industry's top five.

A common fear is that AI just names the same two or three giants. It mostly doesn't — even the category leader captures only 2–8% of recommendations, and it takes 17 to 76 brands to make up half. The same holds for the sites AI cites: a sharp specialist like RTINGS gets cited far more than its fame would predict. The door is open for challengers — brands and publishers — in a way the "AI favors incumbents" narrative misses.

The playbook

The one sentence: AI recommends the brands written about on the sites it cites — so getting featured on those sites (earned media, digital PR) is the highest-leverage AI marketing move there is. How to execute:

1. Pull your category's citation short list. Every industry has ~4–6 sites AI leans on. That's your target media list.
2. Get into the roundups and reviews on those sites. AI reads "best X" listicles and comparison pages. Being in the roundup on NerdWallet or TechRadar beats a page on your own site.
3. Build a real Reddit and YouTube presence — through genuine participation and creator relationships, not spam.
4. Chase specialist coverage, and weigh durability. Placements on big platforms (Reddit, YouTube, Forbes) are the most durable; niche-specialist placements win now but are more retrieval-dependent — a portfolio, not a single bet.
5. Measure across engines, repeatedly. Any single reading is noise.
6. If you're a challenger, move now. 85% of recommendations already go outside the top five.

Earned media just became AI distribution

For a decade, "get covered on the sites your customers trust" was a brand and traffic play. Now it's how you get recommended by the AI that's making the buying shortlist. The brands moving first are getting baked into AI answers while their competitors are still optimizing for page one.

Two things we can do with this instrument:

• Map your category. The exact sites AI cites for your industry, the competitors beating you into the answers, and where you're missing — your earned-media target list, built from data.
• Get you onto them. Earning that coverage is Fractl's core work. The AI shift just made it the highest-leverage channel there is.

First step, today: ask ChatGPT, Perplexity and Google AI Mode the top buyer question in your category. Note who they recommend and which sites they cite. If you're not on those sites, that's your roadmap.
