73% vs 11%: Why Big Brands Win AI Search, and How Smaller Ones Catch Up
Across 102 brands, AI visibility fell in clean tiers: global brands appeared in 73% of unbranded answers, mid-market in 44%, niche in just 11%. It looks like the giants own AI search. But the ladder isn't fixed, and it isn't about your website. Here's why brand stature decides AI visibility, and the four levers challengers use to climb.
Across our study of 102 brands, AI visibility fell into clean tiers by brand stature. Global brands appeared in 73% of unbranded AI answers; mid-market brands in 44%; niche brands in just 11% — roughly 30 points per step down. It looks like the giants own AI search. They have a real head start, but the ladder is not fixed, and the climb is not about your website. Here is why stature decides AI visibility and the four levers challengers actually use to move up.
73 / 44 / 11%
Unbranded AI visibility by brand tier — global, mid-market, niche. About 30 points per rung.
The data is from our study of 102 brands across ChatGPT, Gemini, Perplexity, Claude, and Grok, published openly on arXiv. The pillar covers all six findings; this post is the deep dive on the first one — the ladder.
AI visibility is a stature ladder
Sort the brands by how established they are — global household names, mid-market challengers, genuinely niche players — and visibility falls in clean steps.
The brand-stature visibility ladder
Share of unbranded AI answers a brand appears in, by stature tier (102 brands, 5 engines)
Each rung costs roughly 30 points of unbranded visibility, and the tiers are real, not sampling noise: the paper reports the split with bootstrap confidence intervals, a Kruskal–Wallis test, and effect sizes up to Cohen's d 2.34. One honest note on method: two of the five engines were measured on a smaller, higher-stature slice of brands, so we pool all five for these tier numbers rather than over-reading any single engine.
The challenger gap is real, and it is not your homepage
The gap a challenger is staring at
Global brands appear in unbranded AI answers ~6.4x as often as niche brands
A global brand shows up in unbranded answers about 6.4x as often as a niche one. The instinct is to blame your own site — better copy, more pages, more schema. But that is not what separates the tiers. Big brands win because the rest of the web already says a lot about them: roundups, comparisons, press, forums, reviews. The models read that web, not your homepage. In the same study, only 2.9% of citations pointed to a brand's own domain. Stature is really a proxy for how much third-party coverage a brand has accumulated — which is exactly the thing a challenger can go build.
You do not climb the ladder by rewriting your homepage. You climb it by getting the rest of the web to talk about you.
How challengers climb the ladder
The study points to four levers, in rough priority order. None of them is "optimize your own pages harder."
| Lever | Why it moves you up | Go deeper |
|---|---|---|
| Earn third-party coverage | Your own site is ~3% of citations; the climb lives on other people's pages | Where citations come from |
| Get onto ranked lists | The listicle is the single highest-leverage page in AI search | Why listicles win |
| Build visible authority (E-E-A-T) | Models cite brands the web already treats as credible | The E-E-A-T playbook |
| Measure on a cadence | Visibility is mostly deterministic, but you cannot read it from one run | Why you measure repeatedly |
The climb is slow, but it is a climb, not a wall. Prior GEO research found targeted work on the right pages can lift visibility by up to 40%. The trick is to benchmark against your own tier — track share of voice versus comparable brands, not the category giant — and treat moving up a tier as a multi-quarter campaign of earned coverage, not a homepage rewrite.
The short version
1. Stature sets your starting line, not your ceiling
73 / 44 / 11 is where the tiers begin, because of accumulated third-party coverage. That coverage is earnable, so the starting line moves.
2. Benchmark against your tier
Comparing a niche brand to a global one is demoralizing and useless. Track share of voice against your real competitive set and aim for the next rung.
3. Spend on earned coverage, not your homepage
Roundups, ranked lists, credible authority signals, measured on a cadence. That is the ladder, and it is the same playbook whether you are Tier 3 or Tier 1.
The giants are not unbeatable in AI search. They are just further along a climb that is open to anyone willing to earn the coverage.

Across 102 brands and 102,025 AI answers, only 2.9% of citations pointed to a brand's own domain. Yet most published 'AI visibility' studies still tell teams to optimize their own pages first. The real structure is a 73 / 44 / 11 stature ladder where third-party pages do the work. Here's everything our arXiv study found, and what to do about it.
Your Website Is Only 2.9% of AI Citations. Here's Where the Other 97% Comes From.
Only 2.9% of the 149,912 AI citations we measured pointed to a brand's own website. Yet most AI-visibility advice still starts with 'optimize your pages.' In AI search your own domain is the floor, not the lever; the other 97% is earned on third-party pages. Here's the full source breakdown, and how to earn your way in.
The Listicle Is the Highest-Leverage Page in AI Search
One content format gets cited more than any other in AI search: the ranked listicle, at 35.7% of content citations across our 102-brand study. Most teams pour budget into their own blog. The leverage is on the 'best X tools' lists other people publish. Here's why listicles win, and how to earn a spot on the ones that matter.
