AI search is rewriting the rules of brand discovery.
Marketers have been asking one question for the past two years. When you ask ChatGPT, Claude or Perplexity for a recommendation, which brands actually get mentioned? The answer may surprise you.
Here’s the thing:
SEO optimization 101 doesn’t work here. AI engines don’t crawl and rank pages like Google… They digest sources. And what we know about how they choose those sources is bizarre.
Some quick numbers to set the stage:
- Most brand websites are basically invisible to AI
- Earned media beats owned media by a mile
- A tiny group of brands are pulling in nearly all the citations
Let’s dig in…
The AI citation landscape (In numbers)
The AI citation gap is huge… And most brands don’t even know they’re losing.
New research from Muck Rack just revealed that 85.5% of AI citations came from earned media, not brand websites. This is huge because of what it means for the traditional content marketing approach.
Think about it:
Brands have been investing into blog posts, landing pages and product pages for years… But AI engines scrape minimal amounts of those pages. Specialist agencies such as Gilroy assist brands to discover where they rank within the AI citation gap. They show clients how to close it using generative AI sources that power engines like ChatGPT, Claude and Perplexity.
Pretty eye-opening, right?
That stat, however, is only scratching the surface. Dig deeper into the decision making of AI engines when deciding who to name, and you’ll find it becomes disproportionately skewed.
The 3% problem
Not every brand gets treated the same by AI engines. Not even close.
A report by Hexagon revealed that 3% of brands capture 71% of all generative search prompts. Essentially the largest players are taking virtually all of the share… Leaving the rest to struggle in what academics are referring to as the “citation desert.”
If you’re not in the highest tier, AI engines pretend your brand doesn’t exist. You can have excellent products. Delighted customers. Robust SEO. None of that matters if the AI doesn’t say your name.
AI search is growing fast
The scary part? This is only going to matter more.
AI generated traffic for US retailers was up 4700% year-over-year in June 2025. Nearly 35% of consumers now use AI tools during the product discovery process. Translation: playing the citation game isn’t some small part of marketing. It’s how most people are finding brands today.
Why brand websites keep getting ignored
Okay, so the data is clear… Brand-owned pages are losing.
But why?
AI engines are programmed to seek consensus authority. They reference sources they can link to, that other sources link to and that don’t sound like an ad. Brand blogs fail those tests almost all the time.
Here’s what AI engines actually seem to reward:
- Third-party editorial coverage
- Community discussions and reviews
- Encyclopedic reference content
- Independent expert commentary
- Structured news reporting
Notice what’s missing. Product pages. Homepages. Salesy blog posts. The type of content most brands have been optimizing for the last 10 years.
Paid content barely registers. Studies indicate that paid content and advertorials represent approximately 0.3% of links cited by AI engines. That’s next to nothing. So forget all of that sponsored placement and promoted articles you’ve been relying on. They’re not working like you think they are.
Which sources AI engines actually trust
If brand websites are out… What’s in?
Analysis of over 680 million citations to Artificial Intelligence revealed a surprisingly narrow set of source types that are repeatedly used by AI engines. It’s not chaotic. There is method to the madness.
The most-cited categories include:
- Community platforms – Reddit, Quora, forums
- Reference sites – Wikipedia and specialist encyclopedias
- Editorial publishers – Forbes, business press, trade titles
- Video and audio – YouTube, podcasts with transcripts
- Professional networks – LinkedIn and industry sites
What’s fascinating is just how volatile these percentages can be. ChatGPT’s share of Reddit citations fell from approximately 60% to 10% within six weeks in late 2025 due to updating one search partner. That’s a wild swing.
And it tells you something important:
Citation dominance is never guaranteed to last forever. Engines evolve. Weightings get tweaked. Those who publish earned media across a diversity of source types are the ones who remain visible when the winds of change blow.
Why distribution matters more than ever
There are mountains of research that prove this theory. Brands present on four or more third-party sites were shown to be 2.8x more likely to be mentioned in ChatGPT conversations than brands on only one external site. Publishing on more outlets has been shown to increase AI mentions by as much as 325%.
The bottom line? Posting on one channel is no longer sufficient. AI wants to see multiple people posting about you across multiple channels.
Closing the AI citation gap
So how does a brand actually get into the cited tier?
The truth is it requires a slightly different playbook than traditional SEO. Backlinks still count for something but branded web mentions now have 3 times more correlation with AI ranking than backlinks. Huge change.
What actually seems to work:
- Earning coverage in high-authority editorial publications
- Getting quoted by journalists as an expert source
- Building presence on Reddit, YouTube, and LinkedIn
- Creating content that others link to and reference naturally
- Making sure the same brand story shows up across multiple platforms
The brands succeeding today aren’t the ones blasting out the most blog posts. They’re the ones showing up in the broadest range of sources. And they’re measuring it – not just assuming.
That’s where most marketing teams still aren’t at. Roughly 47% of brands worldwide have yet to implement any generative engine optimization strategy whatsoever. That leaves massive opportunity for those who take the initiative first.
Bringing it all together
It’s really not rocket science when you look at the AI citations data. Brand websites are becoming marginalized. Earned media is carrying the load. And a handful of brands are silently stealing the spotlight while others go unseen.
To recap the key numbers:
- 85.5% of AI citations come from earned media
- 3% of brands capture 71% of all citations
- Multi-platform brands are 2.8x more likely to be cited
- 47% of brands still have no AI citation strategy
SEO will always be important. But it needs to extend beyond your website now. If brands want to be visible when consumers ask AI like ChatGPT, Claude, or Perplexity for recommendations, content needs to be marketed outside of the brands’ website.
The citation gap exists. The opportunity to close it is right now. And the brands that leap first are the ones who will remain visible when AI-powered discovery takes hold.
