Which factors actually influence brand mentions in ChatGPT, AI Mode, and AI Overviews?
I analyzed 75,000 brands to find what correlates with AI visibility:
- YouTube mentions: 0.737 correlation – Strongest signal across all platforms (beats everything else)
- Branded web mentions: 0.66-0.71 – Still crucial for AI visibility
- Branded anchors: 0.511-0.628 – Matters more in AI Mode (0.628) than others
- Link volume: ~0.194 correlation – Almost no relationship with AI visibility
- Content volume: ~0.194 correlation – Publishing more pages won’t help
Platform differences:
- AI Mode rewards established brands most (highest correlations with brand authority signals)
- ChatGPT shows weakest authority correlations – best entry point for emerging brands
- AI Overviews values domain rating more than others (but still less than brand signals)
Bottom line: YouTube presence and brand mentions matter most. Traditional SEO metrics like backlinks and content volume barely move the needle.
I ran this test because everyone keeps asking: “How do I get my brand mentioned in AI search?”
The answer isn’t what most SEOs expect.
I analyzed 75,000 brands using Ahrefs Brand Radar data from September 2025. Here’s what actually correlates with AI visibility across ChatGPT, AI Mode, and AI Overviews.
YouTube Mentions Beat Everything
Two factors showed the strongest correlation with AI visibility: “YouTube mentions” (0.737) and “YouTube mention impressions” (0.717).
They beat every other factor we tested – including branded web mentions, which topped the list in earlier research.
YouTube mentions = any time your brand name appears in a video title, transcript, or description. YouTube mention impressions = those mentions weighted by video views.
When brands get mentioned more on YouTube, they show up more across all three AI platforms.
This makes sense for AI Mode and AI Overviews – they’re owned by Google, YouTube’s parent company. Both cite YouTube more than any other domain.
But ChatGPT showed almost identical correlations, and YouTube is its sixth most-cited domain.
This isn’t just a “Google thing.” The YouTube-AI visibility relationship holds up regardless of platform.
Here’s why: YouTube isn’t just part of AI output – it’s part of the training data.
Both Google and OpenAI trained their models on YouTube transcripts. The New York Times reported that OpenAI’s GPT-4 was trained on over a million hours of YouTube transcriptions.
When YouTube data is baked into both training and output, these correlations make sense.
Interesting finding: volume of mentions matters slightly more than reach. Brands mentioned in low-view videos aren’t at a huge disadvantage, as long as they’re mentioned widely.

Brand Mentions Still Matter
Branded web mentions correlated strongly with AI visibility (0.66-0.71) across all platforms.
More web mentions = more visibility in ChatGPT, AI Mode, and AI Overviews. Not just one platform.
Brands mentioned across different contexts (blog posts, anchors, video transcripts, descriptions, titles) show up more in AI responses.
Branded anchors and branded search volume also correlated with AI visibility, but to a lesser extent.
These brand reputation signals matter more than domain rating and classic SEO authority metrics.
Link Building and Content Volume Don’t Help
Very weak correlations between link metrics (number of backlinks, URL rating) and brand mentions across all AI systems.
Almost no relationship between content volume (number of site pages) and AI visibility. Correlation: ~0.194.
Some SEO experts recommend programmatic content to boost AI visibility. The correlation data doesn’t support this.
It’s not a content creation arms race.
Same goes for link building – building tons of links for volume’s sake won’t help. What matters is getting mentioned across a broad range of sites.
AI Mode Favors Established Brands
AI Mode showed consistently stronger correlations with traditional brand signals than ChatGPT or AI Overviews:
- Branded web mentions: 0.709 (vs 0.664 ChatGPT and 0.656 AI Overviews)
- Branded anchors: 0.628 (vs 0.511 and 0.527)
- Branded search volume: 0.466 (vs 0.352 and 0.392)
- Branded traffic: 0.357 (vs 0.235 and 0.274)
AI Mode acts like a consensus engine, recommending brands most people already know and search for.
It’s the only platform where branded anchors crossed into “strong” correlation territory (0.6+). Other platforms showed moderate correlations around 0.5.
Branded anchors aren’t just mentions – they’re deliberate endorsements where someone linked to your brand by name. They sit at the intersection of brand popularity and authority.
AI Mode weighs these intentional brand references more heavily than other platforms.
For emerging brands without household name status, AI Mode looks like the hardest platform to break into.
ChatGPT Cares Less About Authority
ChatGPT showed the weakest correlations for almost every traditional brand authority signal – branded anchors, branded search volume, branded traffic, domain rating, backlinks.
It’s less influenced by established brand dominance than AI Mode or AI Overviews.
This means it’s more likely to mention brands with varied digital profiles, not just the big players.
Google’s AI products tap into decades of search quality algorithms. ChatGPT has its own prioritization methods, but 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. It’s less gated by traditional SEO authority metrics.
AI Overviews Values Domain Rating More
Besides YouTube mentions, domain rating is one of the only factors where AI Overviews showed stronger correlations.
The difference is modest though. DR is a mid-tier correlating factor – much weaker than branded signals like web mentions and branded anchors.
AI Overviews deliver factual, one-shot answers to informational queries. Unlike AI Mode and ChatGPT, which handle conversational back-and-forth.
Having one chance to answer correctly with limited context may explain why they favor high-DR sources slightly more.
All Three Mention the Same Big Brands
Despite different selection philosophies, the same brands generally appear across all AI assistants.
Correlation between brand mentions in AI responses:
- AI Overviews & AI Mode: 0.821
- AI Overviews & ChatGPT: 0.749
- AI Mode & ChatGPT: 0.769
AI Mode might weigh branded anchors heavily. AI Overviews might care more about DR. But at the end of the day, they’re mostly mentioning Nike, Apple, and Amazon.
Same big players dominate, just through different paths.
What This Means for Smaller Brands
Clear hierarchy: YouTube presence and brand mentions matter most, followed by branded anchors and search volume. Traditional SEO metrics like backlinks and domain authority matter less.
If you can’t compete on brand recognition yet:
Build YouTube presence – Strongest signal across all platforms. Get mentioned in video titles, transcripts, descriptions.
Earn genuine mentions – Get discussed in articles, guides, forums. Focus on breadth across different sites, not volume from same sites.
Target ChatGPT first – Shows weakest correlation with established brand authority. Most accessible entry point for emerging brands.
Different platforms have different thresholds. ChatGPT is easiest to crack. AI Mode is hardest without established brand recognition.
Don’t chase low-quality links or churn out content for content’s sake. The data shows these categorically won’t help.
Brands with strong YouTube presence, widespread mentions, and branded anchors are the ones appearing in AI responses. Whether these factors directly influence AI systems or they’re just markers of existing brand strength, they give us something concrete to work toward.
