Each brand was cited in AI searches over 70% of the time. Its closest competitor managed just 28%. The difference wasn’t authority. It was a video.
That’s the hook, and it’s not a hypothetical. Here’s what I uncovered this week.
The audit that stopped me in my tracks
I was running an SEO and Answer Engine Optimisation (AEO) audit for an air conditioning manufacturer. The goal was simple: figure out which brand dominates when buyers ask Google and AI assistants for recommendations and why.
I lined up the major players in Australia and tracked how often each appeared across AI Overviews, AI Mode, ChatGPT, and Perplexity.
On paper, this should have been a close race. Every brand I analysed ticked the classic boxes.
Good content. Strong links. Solid domain authority. It’s the kind of SEO foundation consultants have been preaching for two decades.
But one brand was being cited over 70% of the time. The nearest competitor? 38%.
When I dug into what separated them, the answer was almost embarrassingly clear: the dominant brand had just launched 55 videos on YouTube in the last 30 days.
That was the variable. Same authority signals across the board, but one company treats YouTube as a serious channel, and the rest treat it as an afterthought.
The data backs this up, emphatically.
I’m not building a strategy off one audit. But what I found in the field maps almost perfectly onto the largest study I’ve seen on this topic.
Ahrefs analysed 75,000 brands to identify which search factors most influence brand mentions in AI. The headline finding is striking: YouTube mentions show the strongest correlation with AI visibility (~0.737), outperforming every other factor across ChatGPT, AI Mode, and AI Overviews.
That’s stronger than branded web mentions. Stronger than domain rating. Stronger than backlinks. And critically, this isn’t just a Google-owns-YouTube story: though ChatGPT has its own methods of prioritization, it doesn’t have the same advanced ranking systems baked in. For brands with modest search volume, backlinks, and web mentions, ChatGPT may be the best entry point into AI visibility, since it appears to be less heavily gated by traditional SEO authority metrics.
In other words, ChatGPT, which isn’t owned by Google, still loves YouTube. So this is a structural truth about how these models work, not a quirk of one ecosystem.
Why YouTube punches so far above its weight
The mechanism is what makes this so durable. YouTube isn’t just a source AI assistants cite at runtime; it’s baked into the training data itself. Both Google and OpenAI have trained models on YouTube transcripts, treating them as enormous natural-language datasets. So video content shapes both the input and the output of these systems.
And the supporting research keeps stacking up. BrightEdge data analysed by Search Engine Land found that BrightEdge analyzed YouTube citation patterns across Google AI Overviews, Google AI Mode, ChatGPT, and Perplexity from May 2024 to September 2025, documenting a 200x citation advantage. A separate Adweek study showed the shift is recent and dramatic: YouTube has overtaken Reddit as the most-cited source in AI-generated responses, capturing 39.2% of all citations compared to Reddit’s 20.3%. This is not a marginal change. YouTube’s citation share more than doubled from 18.9%, while Reddit dropped from its dominant 44.2% position.
The trajectory is steep, too. BrightEdge data from late 2025 showed YouTube citations rose in Google AI Overviews by more than 300% since the beginning of August.
The most important nuance: it’s not about views
Here’s the part most brands get wrong. They assume you need viral, high-production videos to win citations. You don’t.
The Ahrefs study found that the volume of YouTube mentions matters slightly more than the reach, and brands aren’t heavily disadvantaged by being mentioned in low-viewed videos, as long as they’re mentioned widely.
It’s the great equalizer. You don’t need to beat MrBeast. You need to have the best-structured answer to the question your customer is asking.
What wins citations
So what should you optimise? The structural signals matter enormously. Video structure affects how frequently a YouTube video appears in AI-generated answers. Videos that include timestamps or chapter markers allow AI systems to reference specific segments rather than the entire video. And there’s a compounding benefit: this structure effectively turns a single video into multiple citation points, expanding the number of opportunities for AI systems to reference it across different queries.
This is why I keep telling brands: AEO isn’t the new dark art. As one framework puts it well, AEO is not new; it’s good content strategy with more challenging attribution.
SEO isn’t dead, it’s the prerequisite
I want to be clear, because the “SEO is dead” crowd loves studies like this. They’re misreading it.
Traditional SEO is the foundation that makes everything else possible. Strong SEO performance is the foundation that makes AEO citations possible. Think of SEO as the prerequisite and AEO as the advanced course. Or, my favourite framing: SEO gets you into the building. AEO gets you invited to the table where the decisions are being made.
What the Ahrefs data does kill is the idea that you can brute-force your way to AI visibility. There’s almost no relationship between content volume, the sheer number of site pages and AI visibility. The same goes for chasing low-quality links. As Ahrefs’ Director of Content Ryan Law put it, “It’s not just a content creation arms race.” Churning out programmatic pages for the sake of it won’t move the needle.
Different platforms, different doors
One more thing the audit reinforced: these platforms aren’t interchangeable. Brand mentions, not just backlinks, are the connective tissue. Brand mentions correlate three times more strongly with AI visibility than backlinks. AI systems train on raw text rather than hyperlink graphs, so unlinked mentions in reviews, industry coverage, and community discussions influence AI recommendations more than traditional link building.
But the path in differs by platform. Ahrefs found AI Mode acts almost like a consensus engine that rewards established household names, making it the hardest surface for emerging brands to crack. ChatGPT, by contrast, is the most accessible entry point because it leans less on traditional authority. So if you’re a challenger brand, ChatGPT is where you plant your flag first.
My three questions for every brand
If you take one thing away from my audit and this research, it’s this: stop treating YouTube as a “nice to have.”
The three questions I now ask every client:
1. What is your YouTube video strategy? Not “do you have a channel” – do you have a deliberate, structured, question-led video plan?
2. Have you aligned it with your business objectives? Volume of mentions matters, but only if those videos map to the questions your customers ask and the products you sell.
3. Are you genuinely being helpful? AI cites the clearest, best-structured answer. Helpfulness isn’t a virtue here, it’s a ranking factor.
The air conditioning brand winning 70% of citations didn’t out-spend its rivals on links or content. It out-published them on the one channel that AI models trust most. The Ahrefs study just confirmed what the audit showed me in real time.
Your competitors are still arguing about whether AI search matters. That’s your window.
