Traditional keywords and backlinks are no longer the sole factors determining the Future of SEO destiny in today’s rapidly evolving digital ecosystem. Search engine optimization is entering a new era, one that is fueled by complex algorithms, natural language understanding, and user-centric content strategies, thanks to the emergence of cutting-edge AI technologies like Google AIO and ChatGPT.
To handle the complexity of AI-powered search and conversational interfaces, this change necessitates a new strategy based on thorough study and data-driven insights.
BrightEdge Study Reveals Major Brand Differences Between Google AIO and ChatGPT
Table of Contents
BrightEdge’s new research has found that Google’s AI Overviews (AIO), AI Mode, and ChatGPT often suggest different brands when answering user questions. In fact, the platforms recommend different brands nearly 62% of the time.
This indicates that each AI tool interprets online information in its own unique way. According to BrightEdge, businesses should think about each AI search platform separately and adjust their strategies to boost visibility across all of them.
How the Study Was Done — And What It Found
BrightEdge used its AI Catalyst tool to study how different AI platforms respond to the same search queries. They ran tens of thousands of identical queries through Google AI Overviews, Google AI Mode, and ChatGPT to compare results.
The findings showed that the platforms disagreed on which brands to mention nearly 62% of the time. Only about 33.5% of the queries returned the same brand mentions across all three AI tools.
In terms of volume, Google AI Overviews mentioned an average of 6.02 brands per query, while ChatGPT mentioned just 2.37.
When users searched with high-intent phrases—like “buy,” “where,” or “deals”—brand mentions appeared 65% of the time across all platforms. This suggests that commercial keywords still play a strong role in AI-generated results, just as they have in traditional search engines.
Certain industries stood out, too. The e-commerce and finance sectors saw brand mentions in 40% or more of the queries across all three AI tools, showing these verticals have stronger visibility in AI search results.
How Each AI Platform Handles Brand Mentions Differently
The study found clear differences in how each AI platform recommends brands—even when asked the same questions.
According to BrightEdge:
- ChatGPT often mentions well-known, trusted brands, even when it’s not pulling data directly from search results. This suggests it relies heavily on its pre-trained language model.
- Google AI Overviews includes far more brand mentions than ChatGPT—about 2.5 times more on average.
- Google AI Mode, on the other hand, mentions brands less often than both ChatGPT and AI Overviews.
Overall, the data shows each platform has its own style:
- ChatGPT leans on brand trust.
- Google AI Overviews focuses on broad coverage, listing more brands per query.
- Google AI Mode is more selective, highlighting fewer brands.
These differences suggest businesses need platform-specific strategies to maximize visibility in AI-driven search.
Why These Differences Matter
BrightEdge believes the variation in brand mentions across ChatGPT, Google AI Overviews, and Google AI Mode is not random. While they argue that “authority” plays a major role, others may see things differently. Still, the insights from their research offer useful takeaways:
ChatGPT – The Brand Authority Advantage
Since ChatGPT relies on its training data rather than real-time search results, it tends to highlight well-established brands that already have a strong online history. This gives certain companies an “authority boost”—even if they’re not actively earning new citations. Brands that have built a reputation over time may already be getting visibility without realizing it.
Google AI Overviews – A Volume-Based Opportunity
Google’s AI Overviews seem to favor more brand mentions, with an average of over six per query. This creates more chances for visibility. BrightEdge notes that there are clear patterns in how Google cites sources, giving smart brands the chance to reverse-engineer these paths and increase their presence—especially while others are still focusing only on traditional SEO.
Google AI Mode – A Focus on Quality
Google AI Mode is more selective, mentioning fewer brands overall. But when it does highlight a brand, it tends to back it up with strong and reliable sources. Brands that make it into these results likely have well-established authority across the web. Getting cited here may be harder, but the reward is stronger brand trust and visibility.
It’s Not Really About Authority — It’s About Training Data
BrightEdge suggests that ChatGPT’s language model relies on “authority signals” when mentioning brands. However, I see it differently—especially when we’re talking about responses generated purely by the language model (not those enhanced by real-time search or live citations).
In my view, there aren’t “ranking signals” like those used in traditional SEO. Instead, the model is simply choosing brand names that are closely linked to a given topic in its training data.
What might look like “authority” to an SEO expert is probably just a result of how often and how strongly a brand shows up in the model’s learning patterns. Here’s a breakdown of what I believe influences this:
Frequency
How often a brand appears in the model’s training data. The more it shows up, the more likely it is to be mentioned.
Prominence
How important the brand is in the context, like whether it appears in a headline versus being buried in a footnote.
Contextual Embedding Strength
How closely the brand is tied to certain topics, based on how it was presented during training.
So, when ChatGPT mentions a brand, it’s probably because the brand is strongly represented in relevant contexts within its training data—not because the model is measuring “authority” in the SEO sense.
That said, I do agree with BrightEdge on one important point: building true authority and producing quality content still matters. Strong branding and credibility will always play a key role—especially when AI tools evolve to include more real-time data and retrieval-based answers.
Recognizing the Patterns in AI Brand Mentions
The research shows that each AI platform—ChatGPT, Google AI Overviews, and Google AI Mode—follows its own patterns when it comes to mentioning brands. However, there are some shared triggers across all three.
One clear pattern is that high commercial intent keywords—like those including terms such as “buy,” “deals,” or “where to find”—lead to brand mentions in nearly two-thirds of cases. This suggests that all three platforms are good at recognizing when a user is ready to make a purchase.
Not surprisingly, industries like e-commerce and finance see more brand visibility. That’s likely because the AI systems understand the strong commercial signals behind search terms in those sectors.
There’s also a positive sign for publishers: queries that ask for “best” products—like “best laptops” or “best credit cards”—lead to brand mentions 43% of the time across all platforms. This shows that AI models are getting better at interpreting comparison-style queries and matching them with relevant brand suggestions.
The Citation Network Effect: How One Win Can Lead to More
BrightEdge introduces an insightful idea they call the “citation network effect.” The basic concept is that getting your brand mentioned on one AI platform can boost your chances of being cited on others as well.
Here’s how it works:
- A well-written, high-quality piece of content could earn brand mentions on ChatGPT, thanks to strong brand recognition.
- That same content might be picked up by Google AI Overviews, appearing in multiple citations due to its thorough coverage of a topic.
- Then, Google AI Mode—which is more selective—might choose to cite it because it sees third-party validation already happening elsewhere.
In other words, citations create a ripple effect. Being featured on one platform builds the kind of trust and credibility that can increase your visibility across other AI tools, too.
So, rather than treating each platform separately, BrightEdge suggests thinking about how your content presence connects across the AI ecosystem.
Traditional SEO Still Matters — And May Be the Foundation
While AI search is growing fast, the future of seo is going to be more complex and challenging. Traditional SEO remains essential—and I fully agree with BrightEdge on that point. In fact, I’d go a step further and say that optimizing for traditional search is the foundation for any effective AI visibility strategy.
BrightEdge’s research shows that strong SEO still plays a major role, especially when it comes to Google AI Overviews (AIO), where optimization directly influences brand citations. While the impact on Google AI Mode and ChatGPT may be less direct, it’s still important.
For example:
- ChatGPT can pull brand names from both its training data and live online content.
- It also sometimes generates brand mentions straight from the language model itself, based on how often and how strongly that brand is associated with a product or service.
This means that if your brand is consistently visible in SEO-friendly content, it’s more likely to be picked up not only by search engines but also by AI platforms trained on web data. Over time, that visibility becomes part of the AI’s understanding of your brand.
Strong SEO helps you win today and trains the AI to recognize your brand tomorrow.
AI is Changing the Future of SEO to get Discovered
BrightEdge wraps up its research with a strong message: AI is opening up new ways for brands to get discovered—but only for those that adapt to the shift.
They explain that we’re now entering an era of “AI-native brand discovery.” In this new environment, visibility isn’t just about ranking high on a search results page. Instead, it’s about being recommended by AI systems, each with its own behavior, logic, and preferences.
Interestingly, the brands that are succeeding here aren’t always the ones with the biggest SEO teams or the most content. Instead, they’re the ones who understand that the differences between AI platforms—the 62% disagreement rate—actually create more opportunities for exposure, not fewer.
As AI continues to shape how users find products, services, and information, it’s no longer optional for brands to learn how these platforms work. It’s becoming a critical part of staying competitive.
BrightEdge puts it well: the disagreement between AI systems isn’t a problem—it’s the new system. And forward-thinking brands are already taking advantage of it.
