Why Brand Mentions & Citations Are the Key to AI Search Visibility

The rules of search have fundamentally changed. Let’s be honest, when was the last time you scrolled past an AI-generated answer to click on traditional search results? If you are like most users, you are probably relying more on ChatGPT, Google’s AI Mode or Perplexity to get instant, comprehensive answers.

But is your brand showing up in these AI responses?

A recent SEMrush study analyzing over 150,000 citations across AI platforms has revealed a shocking truth—traditional SEO rankings no longer guarantee visibility in the AI era.

The study found that AI Mode responses show only 51% overlap with Google’s top 10 organic results at the domain level and just 32% at the URL level. This means more than half of what AI engines are citing does not even appear in traditional search results.

So what does this mean for your business? Simple. If your brand is not being mentioned and cited across the right platforms, then you are invisible to the millions of users who now prefer AI-powered search over traditional Google results.

The SEMrush Study: How AI Mode Works vs. Traditional Search

The SEMrush team analyzed 5,000 randomly selected keywords across Google Search, Google AI Mode, ChatGPT and Perplexity, uncovering patterns that should make every marketer rethink their SEO strategy.

Here is something that might surprise you: 92% of AI Mode responses feature a sidebar showing approximately 7 unique domains.

Think about that for a moment, nearly every AI search is displaying multiple sources, not just one “winner” like traditional search.

These sidebar citations show only 51% domain overlap and 32% URL overlap with Google’s traditional top 10 results. What does this tell us? AI engines are making independent decisions about what sources to trust and cite.

In just 7% of AI Mode queries, additional links appeared below the response. But here is the kicker that these links showed an 89% domain overlap and 80% URL overlap with Google’s top 10 results.

It is almost like AI Mode runs on two systems: one for broad exploration (the sidebar, which experiments with diverse sources) and another for precision (the below-response links, which closely mirror traditional rankings).

Another fascinating finding is the role of user-generated content platforms. Reddit, YouTube, and even open-source sites like OpenStreetMap consistently appeared among the top citation sources across AI platforms.

In fact, Reddit showed up in more than 68 percent of AI Mode results. This is not a coincidence. Google recently struck a licensing deal with Reddit and it is clear that AI engines now consider UGC as a major trust signal. Finally, query intent made a huge difference. For commercial searches “best CRM for startups” or “top IT support services”, AI responses were almost twice as long as informational ones.

This indicates that AI sees commercial queries as high-stakes moments where users want more context, comparisons and details before making decisions.

The study revealed distinct “citation personalities” among AI platforms:

• Perplexity showed the highest overlap with Google’s top 10 (91% domain overlap)
• AI Overviews maintained significant overlap (86% domain, 67% URL)
• AI Mode demonstrated more independence (54% domain, 35% URL overlap)
• ChatGPT showed the least overlap, often citing different pages from the same trusted domains

Now, what does this tell us? Simple: AI search engines are citation-driven ecosystems. If your brand is not mentioned, you are invisible.

Why This Matters for Brands

If your SEO strategy is still focused solely on climbing Google’s rankings, then you are fighting yesterday’s war. The battlefield has shifted and the new rules are clear:

Traditional Rankings Don’t Equal AI Visibility
Ranking #1 on Google does not guarantee a spot in AI answers. LLMs often cite pages buried beyond position 21+, showing AI plays by different rules.

Citations Beat Rankings
AI engines value credible mentions over rankings. If your brand is not in roundups, industry content or community discussions, you are invisible in AI search.

UGC Shapes Authority
Platforms like Reddit now influence brand trust. Authentic mentions and discussions there directly boost your AI credibility.

Commercial Queries Raise the Stakes
AI-generated commercial answers are twice as long—leaving more room for competitors. If you are not cited, rivals win the mindshare before customers find you.

The New Rules of SEO in the AI Era 

So, what should you do differently? Let’s break down the new strategy:

Keep Traditional SEO Strong

Don’t abandon traditional SEO, instead amplify it. The study showed that domains with strong Google rankings are more likely to be cited by AI engines.

However, this correlation exists at the domain level, not necessarily at the URL level. Focus on building domain authority across a wide range of relevant topics.

Track AI Citations Like Your Business Depends on It

Because it does. You need to monitor where, how and on which platforms your brand is being referenced.

Are you being mentioned in expert listicles? Industry roundups? Community discussions? This is not just about vanity metrics but mentions directly influence your AI search visibility.

Build Mentions Strategically

It is time to think beyond backlinks and start thinking about mentions. This means:

• Securing placements in expert listicles and industry roundups
• Building relationships with journalists and industry publications
• Encouraging authentic community mentions and discussions
• Creating reference-worthy, authoritative content that others want to cite

Align Content Depth with Query Intent

The study revealed clear patterns: informational queries get concise responses, while commercial and transactional queries get detailed, comprehensive answers. Match your content strategy accordingly. For commercial topics, go deep.

Provide comparisons, explanations and comprehensive coverage that AI engines can reference when users are making purchasing decisions.

Invest in Generative Engine Optimization (GEO)

Traditional SEO focused on keywords and rankings. GEO focuses on entity signals, mentions, and AI-ready formats.

This means structuring your content in ways that AI engines can easily understand and reference, building topic clusters that establish your expertise and ensuring your brand is consistently mentioned in authoritative contexts.

How Brand Mentions Drive AI Visibility

The SEMrush study makes it clear: mentions are the fuel for AI citations. Even without hyperlinks, AI recognizes mentions as valid signals. Mentions in trusted sources, say Forbes or TechCrunch which carry more weight than a small blog.

Mentions across multiple platforms also create “cross-engine authority,” making it more likely that your brand will be cited not just in Google AI Mode but also in ChatGPT and Perplexity.

Take the case of Mapbox. Despite having relatively limited visibility in Google’s traditional search results, it became a frequently cited source in AI responses.

Why? Because its documentation is clean, structured and widely used by developers. That made it easy for AI to pull in references.

Similarly, OpenStreetMap—powered by continuous community contributions earned citations across platforms despite minimal Google presence.

The lesson here is that being reference-worthy matters more than being ranked.
