AI Recommends Your Brand, Then Cites Someone Else — Only 2.8% of Citations Are Brand-Owned

A study of purchase-decision queries analysed 1,851 sources cited across Google AI Mode, ChatGPT and Perplexity and found only 2.8% were brand-owned pages, with 59% coming from third-party review sites. Here is the difference between being recommended and being cited, and what it means for how you set GEO goals.

AI Recommends Your Brand, Then Cites Someone Else — Only 2.8% of Citations Are Brand-Owned

You are paying for GEO. The goal on the contract reads "get our site cited by AI."

Three months in, you ask ChatGPT to recommend a few brands in your category — and it names you. Then you open the sources: Good Housekeeping, a reviewer's blog. Not one link to your site.

That is not a failure. You merged two different things into one goal.

Key takeaway: A study of purchase-decision queries (Shero Commerce) analysed 1,851 sources cited across Google AI Mode, ChatGPT and Perplexity. Only 2.8% were brand-owned pages; the largest category — 59% — was third-party review and content sites such as Good Housekeeping, Verywell Fit and Reviewed.com. Being recommended and being cited are different goals requiring different work.

What the Study Found

The data, with its scope stated up front.

Item Detail
Conducted by Shero Commerce
Platforms Google AI Mode, ChatGPT, Perplexity
Sample 1,851 sources cited across the three platforms
Coverage 60 product categories, 8,573 product descriptions from 883 stores, raw HTML from 173 stores
Query type Purchase-decision questions

Two headline findings:

  • Of 1,851 cited sources, only 2.8% were brand-owned pages
  • The largest source category accounted for 59% — third-party review and content sites

⚠️ Scope first: this study covers purchase-decision questions in a commerce context. Asking "recommend a dehumidifier" and asking "how should we plan a B2B SaaS rollout" do not produce the same citation behaviour. Do not apply 2.8% to every query type.

Why AI Mentions You Without Citing You

Understanding this requires accepting something slightly uncomfortable: when answering "what should I buy," the model needs what third parties say about you, not what you say about yourself.

Think about how a friend answers "which dehumidifier brand should I get." They cite reviews they read, a colleague's experience, forum comments. They do not recite a brand's product page copy.

Models behave similarly here. On recommendation-type questions, brand-owned pages are inherently lower-trust sources — because every brand says it is good.

That explains both numbers: why 2.8% is so low, and why third-party sites reach 59%.

The two goals look similar written down. The work behind them is not.

Recommended (brand mention) Cited (citation)
Meaning Your brand name appears in the answer Your URL appears in the source list
Determined by The model's existing knowledge plus retrieved third-party content Whether your page was retrieved and judged a suitable source
Main lever Third-party mentions, reviews, discussion, press Your own site's content depth and crawlability
Drives traffic? Usually not directly Possibly — source links are clickable
Best-fit query type Recommendation, comparison, "what are my options" How-to, definition, specification, "how do I"

Both are worth pursuing — but set and measure them separately.

The common failure is a contract that says "improve AI citation rate" when what the executive actually wants is "AI recommends us." Three months later both sides argue against different expectations.

How to Adjust the Goal

The levers sit outside your control, which is the bad news, but the method is clear:

  • Earn inclusion on third-party review sites: first find which sites AI actually cites in your category (method below), then pursue inclusion or submit for review
  • Cultivate genuine user discussion: forums, communities and review platforms are a major route by which models come to know you
  • Keep the basic facts consistent: brand name, product lines and official descriptions should match everywhere — contradictory information confuses models

If you want to be cited

The levers sit on your own site, which you do control:

  • Shift toward how-to and definitional content — brand-owned pages are far likelier to be cited on these than on recommendation questions
  • Make sure AI crawlers can reach you: this is the precondition; nothing follows without it
  • Put the answer near the top: retrieval favours passages that answer the question directly, not ones that build up to it slowly

How to Test Your Own Situation

Do not infer this. Measure it. You can run this yourself; the only cost is time.

Step 1: write 10-15 real questions

Use the words your customers actually use, not keywords. Split them into two groups:

  • Recommendation: "recommend a few X," "what are my options for X," "which X is better"
  • Informational: "how do I X," "what is X," "what should I watch out for with X"

Step 2: ask on fixed engines and record two things

For each question, record:

  1. Was your brand mentioned? (recommended)
  2. Is your URL in the source list? (cited)

Step 3: also record which third parties were cited

This column is the most valuable — it tells you who AI actually trusts in your category. That list is exactly who you should be working with on the "recommended" track.

Step 4: repeat on a fixed cadence

Monthly, same questions, same engines. The point is not any single absolute number; it is watching change through the same ruler.

This follows the same logic as the measurement approach in How to Measure GEO Performance: rather than buying a score whose computation you cannot inspect, record it yourself under fixed conditions.

FAQ

Does 2.8% apply to my industry?

Not necessarily. That study focused on purchase-decision questions in a commerce context. B2B, professional services and technical queries may behave very differently. Run the test above against your own category.

Should I still invest in my own site content?

Yes. The finding concerns brand-owned pages on recommendation questions. Informational, how-to and specification queries behave differently — those are exactly where your content gets cited. Your site is also one of the sources by which models learn who you are.

Can I pay a third-party review site to write about me?

Be very careful. Paid-but-undisclosed review content carries legal risk and breaches most platforms' policies. Legitimate routes are submitting products for review, supplying information, and earning normal editorial coverage — but you cannot buy the conclusion.

AI mentions us but does not cite us. Does that count as results?

Yes, but be clear about its nature. Being mentioned affects awareness and final choice; it does not directly drive traffic. If your KPI is tied to traffic, set a separate citation goal.

Why does AI trust third-party review sites more?

Because every brand says it is good. On "which is better" questions, third-party content is inherently treated as the more neutral source — the same instinct a person applies when recommending to a friend.

Conclusion: Decide Which One You Want First

"Get our site cited by AI" and "get AI to recommend our brand" differ by a few words on a proposal and by a great deal in practice.

Before you commit the next budget, run the fifteen-question test. You will quickly learn who AI actually trusts in your category — and that list usually carries more information than any GEO proposal.
